3 Things I Learned From Owning a Swimming Pool

After working in the pool business for years, my family and I finally decided to take the plunge and build our own pool. This was our first venture as pool owners. Now that I have had a pool for three years and after getting help from eXp Realty, I have learned several lessons that I did not know prior to owning a pool. You could say I went from book smarts to street smarts as a pool owner. The three biggest things I have learned from pool ownership are:

  1. A lot of Evaporation occurs
  2. You add a lot of Salt
  3. You add a lot of Acid

A lot of EvaporationSwimming Pool Evaporation

I was blown away by how much water is lost due to evaporation. Normally pools see ¼ – ½ inch loss of water per day due to evaporation. This is roughly 2 – 4 inches per week. For a normal sized pool you will loose 25,000 to 50,000 gallons of water per year due to evaporation. This means I was putting a hose in the pool every 7-10 days to fill the pool. On several occasions I went out to the pool and I was sure I had a leak. I ended up doing the bucket test. This is a test where you place a bucket on your deck and fill it with water. You then mark the water level in your skimmer. After a few days you check to see if the level drop in the bucket is the same for the pool. If it is the same then it is due to evaporation and not a leak. The bucket test confirmed my water loss was due to evaporation.

After a few times of forgetting to turn off the hose and flooding the pool deck, running the skimmers dry and just the hassle of pulling out the hose I decided to invest in an Automatic Pool Leveler. This is my favorite equipment that I have purchased for the pool. Common factors which cause increased evaporation are hot temperatures, pool heating and strong winds. One last item which can cause water loss is excessive filter backwashing.

I have been really happy with my Pool Salt System, in fact, it is one of the favorite pieces of equipment I have on my pool. A Pool Salt System Works by Adding Salt to Your Pool and then the saltwater passes through an electrode where chlorine is produced and it is sent back to your pool. Since salt does not dissolve out of water you only need to add salt when you experience heavy rain, water is splashed out of the pool or you have water loss due to evaporation. My estimate was that I would add a “few bags” of salt at the beginning of the year and then add a few bags throughout the year.

Since evaporation in Florida occurs often because of our excessive heat this means I have added quite a bit more salt than I originally assumed. I have a pretty large pool (coming in at just under 40,000 gallons) and I would estimate I have added 30 bags of salt in the span of a year. This is quite a bit more than my original estimate of “a few bags”. Even with this larger amount of salt needed to maintain a pool I would still highly recommend a salt system. Just know that the cost savings over traditional chlorine may be a little less since you have the cost of adding salt to the pool throughout the year.

You add a lot of AcidPool Acid

When you have a salt system, your pool water’s pH levels will tend to increase. High pH levels lead to scaling on the pool tiles, pool equipment and pool walls. To combat this increase of pH you add muriatic acid to the pool to decrease your pH levels. To maintain the proper pH levels in my pool I need to add roughly one gallon of acid per week which is much higher than I anticipated. Normally I will test my pool water every Sunday and without fail my pH level is high. I then add acid to bring the pH level down to the ideal range of 7.2.

I did add an automatic acid dispenser to the pool to automate the process of adding acid to the pool, but it has not been without problems. The idea is good, but there are a few kinks that need to be worked out. The main issue I had is that the probe which measures the acid did not read accurately so the dispenser would not switch on to dispense acid. After many failed attempts to fix the acid dispenser, I have gone back to adding acid the old-fashioned way – by hand.

I truly believe the best way to learn the ins and outs of a product is by owning it and a pool has been no exception. I hope the lessons I have learned from owning a pool can help you in some way. If you have any lessons that you have learned from owning your pool we would love to hear from you, so feel free to post them to the comments section below.

    Hi. Thanks for all the good advice here. We are having the same problem with our pool – losing 1/4″ a day, having to fill it back up every week or two, and having to put in lots of salt. I also did the “bucket test” and it showed that the water level in my pool was dropping at a faster rate than in the bucket. I had a question about that though – the water in the bucket is not moving; we have a waterfall which keeps the water in the pool constantly agitated for at least 8 hours a day. Wouldn’t that lead to faster evaporation? Thanks.

      Another accurate test (some might say, more accurate) is the one our friend Jason at Aaron’s leak detection describes in this Poolside Chat: Does my pool have a leak, or is it just evaporation?. Give this method a try and tell us how it goes.

    Hello!
    We had a bad leak in our old pool liner, and just got the new one in mere days ago. But I am still seeing the water go down in the pool. Yesterday it was about an inch loss, I refilled it, and this morning it was down about a 1/2 inch already. I am wondering if evaporation could account for this. I will do the bucket test tonight but it seems so odd that with a brand new liner we would still be seeing an inch a day loss.

    1. Matthew Simmons Avatar

      Evaporation could account for a quarter of an inch, but not 1-inch.

    So how much does it cost to keep adding water to the pool? Or better, how much does a pool cost per year for al the water, maintenance, electricity, etc? I’d like to know the annual cost before I decide to have a pool installed in my back yard.

    Thanks.

    We have an inground saltwater pool. The first year we moved in, there were three leaks detected- 1. One liner tear 2. Pipe disconnection near pump and 3. We have an in ground pool cleaning system and there was a leak detected in one of the sections (we bypass that cleaning section to avoid the leak). My concern is, we do have to add salt multiple times a year and add water daily. We don’t usually lose more then 1/4-1/2 inch a day. Should I be overly cautious and worry about a missed leak?? We live in Knoxville TN and do have pretty humid summers.

    1. Matthew Simmons Avatar

      You can lose a quarter of an inch of water to evaporation every day in the summer months. That is normal. Not sure what the temperatures are like for you right now, but you should not lose that much water; especially if it humid. All the leaks need to be found and fixed, that is the main thing.

      Why would you be worried about being overly cautious?

        So is it a problem that we’ve just by passed one of the leaks and didn’t fix it?

        We just opened the pool today, so far looks like the water has remained level. I just worry that we don’t lose over the “ok’d” about but still have to add salt 3 times ish a year.

        1. Matthew Simmons Avatar

          If the bypass is permanent and no other leaks spring up then it should be fine. Salt doesn’t leave your pool unless the water drains or it is taken out little by little from swimmers splashing and getting out of the pool.

    Need for adding salt: I agree that salt does not evaporate. But, if your chloranator is not properly grounded or possibly faulty it will not produce the correct electrolysis. This could cause the need for adding salt.

  6. […] Did you know that a pool loses anywhere from ¼” to ½” every day due to evaporation? […]

    Hi, we added a water softener to our house, which is connected with the water we used to fill our pool. We live in northeast florida. The pool is a 24 round doughboy, with an expandable liner and deep end in the middle, half in the ground. We noticed our water levels starting to drop around October of last year. We are losing approximately 1 inch per day. We have checked all of the areas everyone says are prone to leaks. I have not been able to locate any and everything seems to be fine. I did however recently locate a slight drip around the filter around the neck, and not sure if that cause so much water loss. I have since tightened the screws. My question is could the water softener cause a greater amount of evaporation? The pool has only been since Oct 2016. The water loss began about six weeks after we had last been in the pool. I am open for any suggestions!!

    1. Matthew Simmons Avatar

      The water softener would not affect the evaporation rate. Losing an inch a day is a leak, and not something seen naturally even in the hottest months. Out uber-experienced pool tech Dan Dougher, wrote an article on finding leaks in above ground pools, take a look, Finding a Leak in an Above Ground Pool.

    we have a heat pump- does that cause more evaporation? I am usually still running but because of other commitments we knew we wouldn’t be using the past two weeks and shut the heater and I noticed the water level hasn’t dropped as much- we don’t lose much over winter maybe add water 2x over winter- but in summer we need to add water every day we did bucket test dye etc and can’t seem to find leak

    1. Matthew Simmons Avatar

      Heat pumps can uptick the evaporation rate of the pool. For a visual example, if you run a hot tub on a chilly night the amount of steamy mist coming off the water is going to be thicker than it would be on a summer night. Also, lack of humidity can be a factor of water evaporation.

      I don’t know where you are in the country, but an Arizona summer is going to be a lot different (and longer) than a summer in Minnesota. it all depends on where you are.

    What are your thoughts on adding stabilizers? I have a 30K saltwater pool which I had put in five years ago. I have seen the same high ph readings in the past but this year I added ph minus and my pool is currently reading on the lower end of normal ph. I have resisted putting in stabilizers as I have heard that once they are added they accumulate and can only be removed by draining the water. I am definitely at the low end of the stabilizer, but have resisted it so far, thoughts??

    1. Gayle Avatar

      I’m in Southwest Florida. If we didn’t have stabilizer in the pool we would stand with a jug of chlorine and poor it in all day long. (ok, just kidding) But the importance of stabilizer is HUGE. The stabilizer reduces UV evaporation of chlorine. If you are careful and only add like a pound or two a week until the desired level of CYN has been met, then you are technically done and shouldn’t have to worry about the chlorine levels as often ( the stabilizer keeps the chlorine in the pool). So just be careful and add only what is needed. Stabilizers are like salt. They both do not leave the pool unless you drain the water or it gets diluted by rain.

        Very good answer Gayle.

    I have a new 20,000 gallon pool. A leak was confirmed in the skimmer and fixed. I am now filling my pool twice a month in the winter time (60-70 degree weather) in Texas. It drops about 3-4 inches over 10 days. I had the company come back who tested and said we don’t have a leak. We do have a lot of wind where we live. Does it seem accurate that we are losing roughly 1.5 inches weekly? It isn’t even summertime yet. Concerned I still have a leak. I plan on doing the bucket test after it stops raining. Thanks.

    1. Matthew Simmons Avatar

      Water should not be evaporating that fast in Winter. We are in Florida, but we do not need to fill it up that much. But, we get more rain than you.

      Have you tried using drops of dye in the pool to find leak in the pool basin? With the pump turned off a few drops of food coloring dye to your pool at a few location in your pool. If there is a leak in the basin, the dye will be drawn to it.
