Good morning! I’ve been getting my pool ready for swimming season...which is only a few weeks away at most here in LA :) Thanks to this forum, I was able to achieve a clear pool with the following test results: FC - 9 (I know this is higher than the target in the chart- but is it hurting...

Morning friends!! This stuff on the bottom of my pool is driving me absolutely nuts and nothing seems to make it go away. I know the pictures show it as brown, but in real life it has a very good orange color to it, almost like a true rust color. I do have well water and I am not sure if this...

Hi everyone, Happy Monday! I had a question on when exactly I should be backwashing. I have always read that once the filter pressure rises by a certain amount (past the clean filter pressure), that was when it should be done. It is just when I look at the little pressure gauge, it never...

Hi All, I am hoping someone can help me out on this one, as I am stumped. Thanks to this forum, I've been able to keep my pool crystal clear for 2 years now. All of a sudden though, my Chlorine level keeps going sky high. My current levels are below. I am not adding any chemicals at...

I apparently love to torture myself over my PH reading, staring at it until my eyes blur. This picture is accurate to what it looks like in real life. Would you add muriatic acid right now? And would you call this right at 8.0 or a tad lower? Hopefully I am not reading into this too much, I...

When I plug in all my numbers, my CSI shows -.3 Here are my numbers: FC: 10 Alk: 90 PH: 7.9 CYA: 90 Salt: 3200 CH: 125 I read the SWG Recommended Chemistry numerous times and my question is...it says once PH reaches 7.8 to lower it back down to 7.5. However, if I bring it down and keep it...

Hi All! I'm excited to be a part of the forum. I am becoming pretty familiar with the methods used here, but still learning. I occasionally like to bring my samples to the pool store to compare with my K-2006 results and it never fails they are so off that I am literally blown away... So I...
