So I've been consistently using about 4ppm of chlorine per day in my pool and I was wondering if that's normal?
The pool calculator says I need to maintain a 4-8 with my current cya so I target 6 - each morning adding a full gallon of chlorine (pool calc says 112oz but I just add the full 128). By the next morning its down to between 1.5 - 2ppm, and I add another gallon to boost it back up to 6. We have two kids and two adults so were not having huge pool parties.
I did the OCLT and lossed less than .5 and the pool looks great, no cloudiness and no algae.
So yesterday morning I covered it with a huge tarp (not a solar cover) to see how much the sun is eating and added my usual gallon. When I checked this morning I had a 5ppm! So the sun must be eating about 4ppm per day.
My pool is in full sun most all the day, and my chlorine cost is $11.33 per 4 gallon case of 12.5% bleach. So I'm spending about $3 per day on chlorine. Seems like a pain to have a case only last four days though. That's a lot of hauling of chlorine from the pool store. Playing devils advocate, it almost seems easier to just use pucks and get rid of half my water each year (I'm on well water so there is no bill for water other than the electricity my pump uses). Cause right now I'm maintaining daily with chlroine / testing, -vs- weekly with the floater.
Also, should I consider covering it daily when the pool isn't in use? Seems that would cut my daily chlorine down to 25oz so I'd get 5 full days out of a gallon.
Thanks in advance for the advice.
