The 5 Worst Pool Advice We Have Ever Heard

Worst pool advice ever

Let’s face it, with access to the internet, a lot of jobs and skills that were once sought out and paid for have become jobs you can do yourself. With a little advice and a Youtube video, you can almost build anything on your own. Still, not all advice given is created equal nor should be treated equally. Unfortunately, in the pool industry, bad advice can sometimes mean hundreds of dollars out of your pocket and a lot of missed time out of your pool. Throughout the years we have encountered a lot of customers who have taken their share of bad advice. We wanted to share the top 5 with you in hopes you won’t make those same mistakes. Caveat Emptor!

“I was told I could just put the chlorine tablets in the skimmer or pump basket.”

I’m saddened to say that we encounter this issue at least five times every season and our response is always the same, “Please do NOT put your chlorine tablets into your skimmer or pump.” Your pump and filter are the two driving forces that keep your pool clean and healthy. Let’s say you decide to put your chlorine tablets, or “hockey pucks” as a lot of people like to call them, into your skimmer. Once your pump and filter turns off, the tablets keep dissolving in your skimmer, forming highly acidic water. Once the pump is turned back on, this same acidic water goes straight into the filter. This can compromise the internal parts of your filter – cartridges, o-rings, and gaskets – forcing you to replace them earlier than normally necessary.

Instead of putting chlorine tablets in your skimmer or pump, we recommend using a chlorinator. A chlorinator will automatically disperse chlorine into your pool according to an adjustable setting on the unit. Chlorinators work with your existing pump and filter and are usually very easy to install. Another option is a floating chlorinator which is just a plastic vessel that holds tablets and floats in the pool. Floating chlorinators are super cheap and can usually be found in local stores like Walmart. Whatever you do, though,  please do not put chlorine tablets into your skimmer or pump!

“My pool guy told me I could run my pump a few hours a day…. but now my pool is green.”

Pool pumps should run on average between 8-10 hours a day. As a basic rule of thumb, you should be able to filter your entire pool within an 8-hour time frame. In other words, your entire pool (in gallons) should pass through the filter in this 8 hour period. If you are not giving your pump and filter enough time to properly clean the pool and keep the chemicals in flow, your pool will turn green. Not to mention, it might be unsafe for even recreational purposes.

As a pool owner, you need to become comfortable with certain pool calculations. If not for yourself, definitely as a means of double checking pool “professionals” who may steer you in the wrong direction. Here’s how you can calculate the minimum time you need to operate your pump

  1. Determine how many gallons of water is in your pool.  (Pool’s length x Pool’s width x Pool’s average depth x 7.5)
  2. Figure out the pump’s gallon per minute (GPM) This information is typically listed on the pump label. Once you find this number, multiply that by 60 to get the gallons per hour.
  3. Divide the gallons per hour into the total gallons in your pool.
  4. This answer gives you the minimum hours needed to run your pump so that your entire pool is filtered properly.

So the next time someone recommends that you run your pump for “insert # of hours”, always refer back to the GPM of your pump. No one likes to swim in a dirty pool and no pool owner likes to spend additional money to fix something that was preventable from the start.

“My pool guy sold me a bigger pump than I had on before because he said the bigger the pump, the less I’ll have to run it.”

When it comes to pumps, bigger is not always better. A pump is limited by the plumbing size set up at your home and the maximum capacity your pool filter can handle. A higher horsepower (HP) means more power and energy is being used to pump the same amount of water, thus causing your energy bill to skyrocket. A higher horsepower draws more amps but does not move the water faster through your circulation system. Instead of reaping the benefits you thought you were getting by increasing your HP, you end up with a higher energy bill, a burnt-out motor, and an oversized pump you spent more money on than you wish you had.

If you need help trying to properly size your pool pump or want to verify if your current HP is accurate, then please check out our how to guide labeled How To Size A Pool Pump.

If you’re looking to save money, our advice is to switch to a dual speed or variable speed pump. By switching to one of these, you are able to operate your pump using less energy. You can operate your pump at the lower speeds during normal circulation and on high speed whenever you clean your pool. And who doesn’t like saving money, right? In short, bigger is not better when determining the horsepower for your pool pump. Over sizing is very common, but very easy to fix. We are always available to verify if your pump is oversized and if you are overspending.

“You can determine if your pool is clean by the smell of chemicals.”

If someone ever tells you this, take a step back, and go in the opposite direction. The smell of chemicals is not an indication of a clean pool, but just the opposite. A properly disinfected pool has no strong chemical smell. The strong smell common to many pools, especially public, is due to something called chloramines. Chloramines are the byproducts of chlorine’s reaction to contaminants brought into the pool by swimmers. These contaminants include perspiration, urine, body oils, and cosmetics.

Therefore, a strong chemical odor is actually an indication that the chlorine in the pool is working overtime due to the excess amount of contaminants and not an indication of it being clean.

“My pool guy told me I could use Vaseline (petroleum jelly) to lubricate my o-rings.”

You should never, ever use Vaseline or any petroleum-based lubricants for any of your o-rings. Most manufacturers recommend a silicone or a Teflon-based lubricant for all o-rings and gaskets. The oil composites of the petroleum jelly will cause the rubber to break down and will completely eat away your o-ring. Although o-rings range in size from really small to very large, never underestimate their power or the importance of their job. Using the wrong type of lubricant can cause leaks and ruin your system.

    I have an above ground fountain 20ft in diameter with about 18in of water, roughly 3500 gal. There are no inlet/outlet connections for hoses. Can I just run the hoses over the top? Please help I’m out of ideas to keep this thing clean and the Algae is beginning to build

    Pool has chlorinator but I was told it would not make chlorine when water drops to certain temp. Running pump during winter so what do I do.

    1. Matthew Simmons Avatar

      What type of chlorinator do you have? Is it salt chlorine, tablet or other?

      If you have a salt chlorine generator, try to find a model number or name on the box.

  3. Ryan Avatar

    So as long as the pump stays on you can put tablets in skimmer correct?

    1. Matthew Simmons Avatar

      The undiluted chlorine can still make skimmer baskets and internal pump parts brittle. This means you will have to replace these parts more often and negating any money you may think you saved by not installing a chlorinator.

      In my opinion, I wouldn’t try to make a bad situation bearable and just plunk down the $10 for a chlorine float. Also, running your pump is going to cost you a bunch in energy costs.

      1. Jimmycrackkorn Avatar

        Skimmer is the only place you should put your tablet it puts the chlorine in the pool quicker skimmer baskets are not that expensive also why would you turn your pump off run it 24/7 keep that water moving

          Thank you for the bad advice.

    Thanks Matthew, yes, I’ll go for Plan A and if that does not work, then I’ll go, as suggested, with Plan B!!

    Hi there Matthew,

    I have a 10′ x 7′ x 4′ small pool made of solid ( 2 inches thick) fiberglass-covered ply. It was originally a large live seafood-holding tank that I have converted into a semi-inground pool. I have sunk it into the ground leaving 1 foot above ground and surrounded it with decking. It has NO holes cut through for draining or return ports; it is just a solid shell.

    My question is, “Do I have to cut drain/return holes in it for filtration/cleaning purposes?”. I would rather just use one of those floating filters that you can attach a pool-vacuum to; and just simply run the out and return hoses that go to the filter over the edge of the pool when I need to run the filter. The filter I have could easily filter the entire pool volume in a couple of hours. Is this possible/viable?

    Thanks for your assistance!!

    Mike

    1. Matthew Simmons Avatar

      Mike that is a good question, but a question I don’t have a solid answer on. My first instincts are to tell you to bite the bullet and install the proper filtration inlets and outlets needed (skimmer, main drain, and returns.) Because I know, this will work and would be a permanent fix.

      I do not have any experience with floating filters so that they may be the cat’s pajamas but I couldn’t tell you one way or the other. If it will do the trick. If worst came to worse, you could try the least expensive method and then if it fails to go with the tried and true method.

    I saw the pool guy trowing powder chlorine in to the pool.
    Question?
    Can this damage my diamond brite, equipment or filters?
    Thank you in advance.

    1. Matthew Simmons Avatar

      The granules could harm the pool surface if the granules do dissolve quick enough. Most pool owners I know, add chlorine to a half filled 5-gallon bucket, mix, then walk around the pool evenly pouring out the mix.

    Hi,

    Firstly, a big thanks for compiling great information which is very helpful for pool owners. We have a big in-ground pool (around 20k gallon). The filter is DE Hayward. This is our first experience with the pool. Novice to begin with, the pool water turned green in a month since we moved into the house. We added Algae corrector and shock but that didn’t help. Later, we realized,our biggest mistake was we mistook DE powder as chlorine and were feeding that in the chlorinator(this was done around 4 times). When we realized what we were doing wrong, we back-washed the DE filter(thanks to your video) and added chlorine tablets to the chlorinator. But the tables arnt dissolving and the pressure gauge on the DE filter shows around 25 psi. what is the best solution to this problem as winter is approaching and we need to close the pool but want to make sure that the pool is in a good condition before we do that.

    1. Matthew Simmons Avatar

      First off, thank you for watching our vids!

      Secondly, what is the model of your Hayward Filter and chlorinator? What is the normal PSI for your filter? Also, do you see DE powder lingering in your pool?

      1. Tony Avatar

        Hey there,
        Although the algae is all clear now but i do see some powdery stuff lingering along the edges of the liner. That might be the DE powder. Is there a way I can upload an image? and if this is DE powder, how can I get rid of it?

        Thanks,
        Tony

        1. Matthew Simmons Avatar

          Uploading images is a little difficult on our blog, you may want to try posting this to the forum for pictures. We have a couple of moderators and regular pool owners that can find you the answer.

          A white powdery substance may be remnants of dead algae or scale. When you post in the forum, make sure you post results of your latest water test.

    Hello,
    We have a saltwater inground fiberglass pool. Our pool guy has replaced everything except the salt cell and motherboard. The motherboard does not work as of yesterday. They are very expensive to replace. Since we have sunk so much money into new pump, tank, pool light etc, can we do something that will chlorinate the pool for the next couple of months until we can replace the salt cell?
    Thanks much!

    1. Matthew Simmons Avatar

      It is pretty simple, get a floating chlorinator, drop in some tablets and you should be set. The chlorine float isn’t the fanciest of equipment but it gets the job done

      1. Lew Avatar

        Just a quick note about using floaters in a vinyl liner pool. We installed a new liner a few years ago and the customer had a floater and it got stuck on the corner of his walk in steps and the bottom of the floater was close to the top step ( this was a pool with the liner over the steps) the highly acidic water distroyed the liner were it was stuck at. FYI

        No change the cell ask him to put a new cell on and turn it on than take a salt reading on a strip. If it dosent add up than change your cell. If you can’t afford it than you should not have gotten a pool. If it is the motherboard which it probably is. But it is a good possibility it is both. Don’t just add chlorine that’s just stupid and your pool will go green if you don’t have your cell regulating the salt and chlorine properly. Or disconnect everything and add a clorinator if you can’t afford your system

    We are first time pool owners we go 17x 58 6.280 gal pop up do we need a sand filter

      Jason,
      You may use any type of filter on the pool; sand is usually the least amount of maintenance making it the most popular among pool users

    My salt chlorinator is leaking profusely around the salt cell and is corroding the unit. I also have struggled all season with maintaining the correct chlorine level. We have super chlorinated and shocked several times this year. I have also developed yellow algae that I am battling. We live in Toronto, Ontario – very hot this summer ( 95+ degrees ). Any suggestions for combating the algae as well as maintaining chlorine levels ? We have had our water tested religiously many times this season….

    1. Matthew Simmons Avatar

      We have a guide on battling algae here, How to Treat Moderate Swimming Pool Algae. But if the chlorinator had been working correctly the algae would not have had a chance to grab hold.

      What are the current chemistry levels of your pool: Chlorine, pH, Alkalinity, and Hardness?

      The steps I would take to try to fix your issue:

      1) Replace the o-ring, union or cell housing (if applicable) to stop the leak. The constant loss of freshly chlorinated water may be contributing to the chlorine loss leading to algae.
      2) Test and/or clean the cell to get it firing correctly. If the cell is still not putting out enough chlorine then you may need a new cell. How big is your pool, and what is the model number of your generator?
      3) Kill the algae. With the cell up and running, plus the right addition of shock and algaecide the algae should go the way of the Dodo.
