First, let me say THANKS for the wealth of knowledge that is available here! You guys seem to be the true professionals!
We have a 14 year old pool with newly replaced vinyl liner, filled with municipal water about 3 weeks ago. Started putting chemicals in based upon pool store recommendations, then stumbled upon your site. What a blessing!!! We spent the past 2 summers fighting algae, and no one at the pool store could explain it. Just kept telling us to add more "shock" and algaecide. I have old print-outs of pool store testing and the CYA level was up as high as 170! Funny that nobody ever mentioned that this was a problem! Anyway, with the new liner and fill, I'm so glad that we found TFP!!!
Using Aqua-Chem strips and bleach and using the pool calculator, we've been trying to get the FC level up until we ordered a testing kit.
Got the TF-100 in today. Here are the numbers:
FC = 4.5
TC = 5 (best guess at reading the yellow color)
CC = <.5 (maybe turned slightly pink after adding R-0003, but 1 drop R-0871 cleared it)
pH = 7.8 (best guess trying to color match, somewhere between 7.5 - 7.8)
CH = 225
CYA = 30 (isn't this low?)
So..... what do we do next? The water is actually clear, and I'm sure that you guys can help us keep it that way. It has rained quite a bit today and more is expected tomorrow. Not sure how that affects things... Thanks in advance for your help!!
