Just want to start by saying WHAT A GREAT WEBSITE!!!!! The information from the postings is phenomenal and I'm sure I will eventually get the hang of it, but for now I need HELP! We opened our new to us, first time ever owning a pool approx. 1 week ago, water was perfectly clear so we took water sample to one pool store who tested and got the following:
We were using Trichlor tabs at the time. We were not really impressed with this pool store so hedged our bets and took it to a second who gave us the following:
so 5 days ago we added ( not knowing any better!) 25 lbs of sodium bicarbonate and 50 lbs of calcium increaser as we were told to do and were told to continue using the Trichlor tabs in our skimmers. We also purched as Taylor K2005 kit. We asked for one of their pool techs to come to the house and make sure we were operating the pump system properly and while he was there he used our kit and tested and found that our CYA level was sitting at 150. He took another sample back to the store to test and 2 days ago ( Friday) we got a phonecall saying that we needed to drain the pool completely to get rid of the CYA. At this point I got really cranky and found this website so yesterday we drained abot 25% of the pool, added fresh water and at 1:30 pm we added 11.37 gallons of liquid clorox and kept the pump running all night ( it also has rained profusely here over the last 12 hours and is about to rain again). Here are my test results as of 2:00 pm:
PH 7 ( this is is TOTALLY not accurate as the test started yellow and then went to a light green after about 1 minute)
CH ?? the test just stayed a dark purple color?
I see the FC/CYA chart says I need to shock to 39 so should I just keep adding the bleach or keep draining and filling the pool until the CYA level drops?? ( is it true that CYA floats at the top of the water level?)
Any advice at this point would be greatly appreciated!!
