I'm noticing a handful of green stains at the bottom of my pool. I recently bought the home and switched to a SWG. The plaster is old, stained, and really needs to be remarcited (it's cosmetic so I don't want to spend the money right now). Anyway, I think the green stains may have been there...

I've added muriatic acid and cyanuric acid to balance the pH and CYA. Here are my current readings: FC 6.5 CC 0.0 CYA ~85-87 pH 7.5 TA 70 CH 250 So, I know I need to lower the FC. Everything else look good? We're entering the sunnier/hotter/humid/rainy season here in South Florida. Any...

I've mentioned it before but I'm not fond of the CYA test. I *think* my CYA level is 60-65. 60 is probably my best guess. I have a SWG that gets a lot of direct sunlight. The pool is screened. I assume I need to raise the CYA and should shoot for 80. What happens if I accidentally go over...

15K gallon pool SWG My levels: FC 5.5 TA 70 CH 250 pH 7.8 So, I guess I need to lower the pH huh? Maybe add 1 cup of muriatic acid (31.65%)? I added two cups yesterday. My pH was at 8.0 and dropped to probably 7.6, but now it's at 7.8. (I should mention I have problems with the pH color...

I apologize in advance b/c I'm a newbie. I love the helpful info in your Pool School section - I've read it and continue to reread and return to it. How long do you recommend running my pump? The pool guy recommended 8 hours/day here in the summer. Does that sound like too much? Keep in...

My levels: SWG FC 5.5 TA 70 pH 8.0 CH 240 Does it matter which I adjust first (pH or TA)? I hope not, as I've already added 1 cup of muriatic acid (31.45%). It looks like you recommend a pH between 7.5-7.6. You seem to recommend a TA level of 60-80 but my Hayward SWG recommends 80-120 TA...

I bought the Taylor K-2006 test kit and am loving it. Great kit! My only problem is with the CYA test. I have a heck of a time being certain of my accuracy with the CYA black dot test. Any tips out there? Should I be reading the CYA level once the black dot first completely disappears from...

Are salt test strips really worth it when my Hayward SwimPure/AquaRite is taking a measurement of the salt content for me? Does anyone know how much more accurate? Does the AquaRite seem to read higher or lower?

Sorry in advance for the stupid question. I've never taken care of my own pool. Ever. I'm switching to SWG and want to do maintenance myself. Does setting the percentage level/run time on the Hayward SwimPure/AquaRite control the pool pump and tell it when to turn on and off? Or, do I need...

I read in Pool School that the liquid costs a lot more; however, I also noticed that the solid can take up to a week to affect levels in a test kit. When I switch to SWG I'll be bringing up the CYA level and I'll want to see the level faster on test kits and respond right away. So, my question...

Okay, I'm making my way through Pool School. I found Water Balance for SWGs helpful. Note: I'll be purchasing the Hayward SwimPure. 1. I don't fully understand CC. Is that the same as chloramine? Why is it important to test for it? 2. In regards to a SWG, what should a good range (or...

I'll be brand new to SWG and to pool maintenance. I've started reading Pool School and plan to really go through it. However, I do have some questions before deciding to purchase my SWG system. FYI - I've decided to go with the Hayward SwimPure/AquaRite. I'm a complete newbie to pool...

My family wants to switch to a saltwater system. I want to our local pool store (Pinch A Penny) and the guy said the best system they sell is the Hayward SwimPure Plus. I'd estimate our pool to be 15,000-20,000 gallons but I'll need to do measurements to find out a more accurate approximation...
