Poolside Chat Episode #33: Why Is The pH Always High In My Pool?

• Why Is The pH Always High In My Pool?

Now here’s your hosts – Matt and Rob.

I’m constantly wrestling with high PH and find myself having to add acid every day or every other day. I am not sure what is causing the PH to rise. Is there a way to add acid or raise alkalinity that’ll keep me from having to do this every day?

-Raymond

Well first, you don’t want to add more alkalinity to the pool because the PH is already high. Some of the causes of PH being high would be if you have a saltwater pool, it’s constantly making sodium hypochlorite which is already high in PH. Another reason might be a new pool surface. Those pool services can leach alkaline materials for up to two years, so you might find yourself adding muriatic acid all the time. A third reason might be if you have to add a lot of tap water. In some areas the tap water is very high in PH so that might be why you’re having to add muriatic acid.

But those are pretty much the causes, but what about a solution?

Well, if you want to avoid going out there every day to add acid, you can always get an automatic acid feeder kind of like the Pentair IntelliPh or the Hayward Sense & Dispense. Now they’ll constantly read your water chemistry and dispense it as necessary, it really cuts out all the legwork for you.
