I've been reading here and learning a lot the last couple of weeks, but I've reached a place where I think I need some help.
We just bought this home in late January, and the water was fine. Now it's green, and I'm trying to clean it up using BBB. I adjusted the pH from 6.8 to 7.2, increased the TA from 50 to 80, then started adding bleach. Trouble is, I'm operating with just a 6-way hth test kit. I ordered my TF-100 test kit a couple of nights ago, but I don't have it yet. I'm not sure how to continue to shock with just one chlorine reading that goes only to 5 ppm. I know I need to add more bleach, but how much?
Last night, I added 12 jugs (121 oz @8.25%), brushed the pool, and waited. This morning, we bakcwashed the filter, so the pressure is back where it needs to be. The green is less dark than it was, and I can see the bottom in the shallow end, but it's cloudy. What next?
OTO-dark orange (Cl is over 20ppm?)
pH was 7.2 when I started to shock
CYA>100 (but last summer's readings on the pump show this same high reading all summer)
CH 200--but that's irrelevant with a vinyl liner, right?
Also, I might have blockage in one of two skimmer lines, but pressure is good in the other skimmer and in the two water jets.
This is my first post after MUCH reading. I really love this site! Thanks for all the help I've already received!
