pH - 7.2
CH - 170
I am a new user, found this site yesterday. Spent the day educating myself from it. Thank you for all the information. I am officially DONE with the local pool shop! I ordered my 2006 taylor kit, but had to start SLAMing the pool immediately. This is why the FC # is 10+. I can't accurately say what it is, but the test water is amber, not even a strong yellow.
My problem began when we opened the pool this spring. (we have had an IG pool for 7 years) We noticed the black slimy fluffly goop around the pool light. We took it out, scrubbed and cleaned it. it has been a cool summer, hence not much swimming, and obviously not enough testing of water. Noticed some patches of dark 'scum' forming in corners of deep end and on floor of deep end. I should have SLAMed then, but I didn't. No problems throughout the summer. Just went away for a week, had neighbor put 1 bottle of liq chlorine in every second day. They noticed it getting 'murky" but didn't tell me. Got home to a greenish pool. UGH. That was Friday 16th. put 4 gl. liq chlorine. 4 again sun and on Mon am the pool was way worse. CYA was 0. upped that and have been fighting it all week.
My ongoing problem IS: the ladder stairs have thick green algae under them caked all over. I'm taking them apart and will soak in liq chlorine. I've been keeping the FC high (10+)and maintaining it constantly. The pool is beginning to turn ever so slightly grey green.
What do I do about the light?. I know there is nasty slimy black fluffy stuff.
When can I expect it to really start looking better? I am beginning to wander if my sand in the sand filter is not working properly. The backwash is not as green as I would expect it to be.
Any advice on the light and time to clear would be appreciated. Many thanks,
