Hi All,
I have a pool issue that is stumping me... it was pretty green and nasty when I first started working on it back in May. I bought the enhanced Taylor testing kit, and now have the following test results (at least the ones I remember right now):
FC 18
CC between .75 and 1.0
CYA 40
PH 7.2
The pool is a kidney shape, 18,000 gunite pool from the late 60's. FC levels were brought into the mid 20's (CYA was over 65 at that time) to ward off an algae bloom, but have been holding fairly steady now instead least the upper teens while I continue to battle this cloudy water.
Visibility is such that I can see the top step int the shallow end and clearly read the plaque of the company that originally built the pool. Unfortunately, that is all the better it has become. I am petty sure that the water is sanitary, but I am quite far from a sparkling pool, despite weeks of 24/7 filtering and constant chemical maintenance.
Last year I switched from the original sand filter to a cartridge -- a Hayward C1750. I bought a new filter cartridge a month ago, and while it helped, the water remains cloudy and I am still stumped...
Is this filter simply too small? The pool is approximately 18,000 gallons. Also, it is unlikely that the plaster was ever re-done.
I had decent results with the sand filter (especially once I put in Zeolite), but the original plumbing sent the waste into the gutter, which is now more than frowned upon. I also don't have the funds to hire a plumber to tap into our sewer main, which is my only acceptable way of disposing of waste water, hence the switch to a cartridge filter.
Any help will be appreciated. We are using the pool, but I would really like for it to look a lot better.
Thanks,
David
