Realize now pH reads high when chlorine is high. Please disregard.

Can CYA reagent go bad? I have been running 50 all season and last tested about 3 or 4 weeks ago. Today I tested CYA and the dot never disappeared. I had a mishap today that turned out OK and I was lucky. I needed to add a couple of inches of water so I turned on the hose an hour before I...

We bought a new heater this season, a Raypak 206,000 BTU NG Electric Heater RHM-15-9962. It heated the pool nicely earlier in the week, but we turned it off when a cool spell was forecast. This morning I tried to turn it on and I get this error message: "Rollout SW Open". What does this...

It is snowing in May. We opened our pool a week ago and have it looking great. Clear, sparkly, balanced water thanks to BBB and the Trouble Free Pool website. The weatherman says it will get down to 32 tonight and 29 tomorrow night. I will leave my new Pentair Intelliflow pump running. Is...

Being in Nebraska, the temp at night is really starting to drop, so I bought a solar blanket. It does a great job of reducing heat loss at night as well as reducing chlorine loss during the day. I faithfully test the water every day, make adjustments and keep everything in range. This week we...

I am considering purchasing a pool cover to reduce heat loss at night. My pool doesn't have a bottom drain, so the only circulation we get is through the skimmer and the returns. Will this be a problem for circulation if I have a cover on?

I don't know what I'm doing wrong. Two nights in a row I tested pH and got 7.2. I didn't believe it and immediately tested again using water from the same sample and got 7.6. A third test showed 7.6. I rinsed the tube each time before testing with the sample water. I am careful when I...

I am getting frustrated with the pH in my pool. Last weekend I brought it down to 7.2, aerated and got the TA to 80 from 120. Now 5 days later, it is back up to 7.6 and TA is 110. Every time I add liquid chloring 12.5%, the pH rises about .2. I did add about 4 inches of fresh water. I...

I add MA at least twice a week because my pH keeps going up and hit 8.0 once. It is 7.8 today. TA is 110, so I don't want to give it a big hit of MA to lower pH. Two days ago I put in 32 oz MA according to the Pool Calculator. I hate it that I am lowering the pH all the time and my concern...

I have an air conditioner serviceman here this morning and he gushed about how beautiful my pool water is! He said he's never seen such a clear pool. Thanks to TroubleFree Pool!

I have been using Liquid Chlorine 12.5% from Menards and notice that pH keeps going right back up after I bring it down. I use Muriatic Acid in amounts according to the Pool Calculator and usually bring it down to 7.4, then within a day or so it is right back up to 7.8 or even 8.0. Alk has...

When we opened 3 weeks ago, the water was crystal clear. After the winter and being closed for 6 months, I somehow didn't have a swamp. Opening was effortless. Now the water is very, very cloudy. There is no color to it, just cloudy. Since we have a Nature 2, I have been keeping the FC...

I have tested several times and finally believe it. My pool's Cyanuric Acid level is between 85 and 100, so I am going to drain half my pool before the swimming season gets started here. I will also quit using Leslie's 3" pucks and start sanitizing with Chlorox. :-D I have a submursible pump...
