I have a 28000 gallon fiberglass inground. Since using the BBB method everything is so easy, balanced, and cheap with pool maintenance, but I feel like I have to add bleach too frequently. Because of the size of my pool, losing half to 2/3 of my FC per day due to sunlight really takes its toll. I have to add sometimes up to 4-5 gallons a week depending on rain/sun/etc. I have been keeping my CYA at around 45. Will bumping the CYA and taking my FC levels up higher help out with how often I am having to test and add chlorine in the pool? I never have CC.
Also, what is the best method to get rid of the fine siltlike material that gets stirred up after large swim sessions? It's stuff that is so fine, my filter isn't catching it and it just clouds the water after we have alot of swimmers stirring it up. I run the filter and it eventually settles back down. I have a good hunch the previous owners did not add pool sand in the filter and used regular old playground or quickset sand, so that will get swapped this fall.
I added 2 cups of DE to aid and that works awesome, but the filter pressure goes up to 25 (from 20, its 18 before DE) within 2 days so I end up having to backwash after about a week. I think some of the DE might be causing some of the cloudiness, but I really don't know. I have a silt bag on my cleaner running about 4-6 hours a day (same as pump unless it gets cloudy).
