advice on my numbers..............

FC:1
PH:7.8
CA:0
TH:220
TA:160


My plan of attack is to get the FC and the CA Up as soon as possible.

We need some more info to offer an opinion. What type and size of pool is this? What type of test kit did you use to test with? What is your CYA (stabilizer) reading? Or is that what you meant by CA? What does your TH reading stand for - total hardness? What are you using to chlorinate with? Repost and somebody here can better advise you.

Welcome to the forum.

watermom thanks........here is the info!!

above ground, 24' pool-13,500 gallon. used walmart 6 way drop test kit. lol....yes CA was meant to be my CYA reading. TH is total hardness. Using bleach to chlorinate with.

FC-1 PH-7.8
CYA-0 Total Hardness-220
TA-160

Any advice on a plan of attack?

Buy some cya. You may be able to buy it at Walmart, Lowe's or Home Depot. It may be called stabilizer or conditioner. Check the ingredient label. If is says cyanuric or isocyanuric acid, that is it. Add enough per label directions to get an initial reading of around 30. Add it to the skimmer while the pump is running. Then, don't retest, add more or backwash for a week to let it dissolve completely.

In the meantime, you're gonna have trouble keeping a chlorine reading in the pool. Probably test it morning and evening and each time add enough bleach to bring the cl back up to 5. After you start getting a cya reading, you'll be able to just test and dose it with bleach in the evenings. Your alk is fine, but you don't really want it much higher. Same with ph. We usually say 7.4-7.6 is best, but anywhere 7.2-7.8 is acceptable. If it goes any higher, you'll want to add a little muriatic acid to lower it some. Hope this helps.

thanks a ton watermom, that is what my plan of attack was. Just wanted to make sure I was on the right track!!
