    chlorine dropping rapidly

    Hey there,

    We get the chlorine to the right balance, then within 3 days the level is back to near zero. We got a floating tablet in there now. run the pimp at 2k from 10-5 then 3400 with the vacuum from 7-9pm. stumped on whats going on. It doesnt seem normal to have to add this much chlorine. PH is usually good, and doesnt fluctuate quickly. Any help would be great, thank you.

    You need to add chlorine daily.

    None of our neighbors add daily. I just read up a bit. we are not adding any CYA. I think that might be the problem.

    You are adding CYA with the floating tablet. You really should be adding chlorine everyday.

    Re: chlorine dropping rapidly

    So how do pool services have good water only visiting every week? Some thing seems off. So I have to add chlorine daily, then when can I swim in the pool if Im always adding chems.

    You can swim daily - even when adding chemicals. Pool services don't have pristine water. If you follow the TFP way you don't need/want pool service.

    As others have mentioned - more reading in pool school is required to wrap your head around the process.

    To answer your Pool Service question more specifically :

    Pool services tend to elevate the chlorine level to "shock" the pool each week and then leave a Tabs in a floater or chlorinator to maintain the rest of the week. In order to compensate for not properly chlorinating the pool they also tend to add phosphate removers and algecide to help keep algae from growing.

    Overtime levels of CYA, Copper and/or calcium build up to the point where the pool has constant "issues" - so you drain the pool and start over.


    The things you'll learn here are a more science based approach to pool care management.

    Regardless - "Chlorine" (Hypochlorous Acid) is used up everyday and must be replenished from some source.

    how did you get those numbers? We strongly advocate for pool care which starts from reliable and accurate testing. It's impossible to make recommendations if you don't know exact levels of the chemicals in the water.
