I have a STA-Rite Max-E-Therm 200 SR200NA that was newly installed in July 2021. The LED screen says the Pool temp at the top then says ERR AGS. From reading the book, I'm a bit confused as to this being something that needs to be fixed or not. It says one of the elements exceeded 140 degrees...

I had the Pentair iChlor30 installed the beginning of August 2021 after a lightening strike killed my old one. Then we closed our pool Oct 1 so it was open for approximately 8 weeks. When I opened it this spring(May), the "low salt" light was on even though the salt level is perfect. When I...

I have a 4 year old Pentair Mastertemp 250 that won't stay running. When I turn it on, I can hear it start up then I can hear the burners light. Then after a second or two, I can hear an audible sound of something "winding down". Then an audible click. At that point the temperature readout...

I've been struggling keeping my PH in the proper range all season and I'm not sure what I'm doing wrong. I've added Muratic Acid multiple times and it comes down butthen immediately creeps up again. Any advice is appreciated. Test results below. FC 4.0 CC 0.0 PH 8.3 TA 150 CH 280 CYA 50...

I replaced my salt cell this week as the old salt cell had stopped working. It was 4 years old which seems to be fairly average based on what I'm reading. When I installed the new one it had something called a Breather Tube inside it. When I looked at my old cell it had a space for a breather...

I have a Pentair Mastertemp 250 that is now entering it's 4th pool season. I went out last night to find the service light on and water leaking from underneath. I'm trying to find what the warranty is on it but all I can find is referencing some card I don't have. Does anyone have any idea...

So this might be a dumb question but I'm having a hard time understanding what's happening(happened). Last week the pressure in my filter tank was high enough that the flow light on the SWG came on. This is the same point and pressure I normally need to back flush so nothing seemed out of the...

So the pressure in my filter tank has been rising rapidly after a backwash. My "no flow" light comes on within 12 hours of backflushing and coincides with the pressure increase in my tank. I know about where the light normally comes on and needs to be back flushed but it usually takes a couple...

So I'm a little confused about the pool calculator. It seems to only tell me how to increase TA and not decrease it. Here are all my numbers: FC 4.25 PH 7.5 TA 110 to 120 CH 170 CYA 30 Salt 3800ppm Any help would be appreciated.

So, we had our pool partially installed fall 2012 then completed spring of 2013 and needless to say the process was a complete train wreck which I won't go into. However, by the end of the summer 2013 everything seemed to be running well and the had the pool closed for the winter. Now that...

So we've had about 85 inches of snow so far in Michigan and approximately 36" of it is piled on my winter cover(inground). Should I be worried about the weight? Not sure if I should go out and try and pull some of the snow off or not. Any feedback would be appreciated.

Is there a specific type on anti-freeze I should use in the skimmer when closing my pool? I had it closed but the water rose and flooded the skimmer again so I need to pump all the water back down, drain the skimmer with my shop vac then put the anti-freeze back in. I'm just not sure what type...

We have a new pool installed this spring. A few weeks ago while swimming I noticed the ends of the steps on the ladder were discoloring or rusting. I asked the incompetent pool company that installed it about the issue and they said it had to do with the salt water. Salt water will rust the...

Last winter (my first winter) the springs from my winter cover wore the paint off my cove molding that goes around the pool. So what I had in the spring was a groove by most of the spring that worked through the paint down to the bare metal. I want to keep that from happening this winter. Any...

How much replacement DE should I be adding back into the system after I backflush? I've asked the same question of 5 different folks at the pool company that installed my pool and git 5 different answers. They told by neighbor (same pool installer) another answer altogether. Is there a good...

Just received and used my TF-100 test kit last night. CYA was low at 30 and cholorine was low at 1-2. I'm a little confused about free chlorine though. How to I figure out what that is again?

We have a Jandy SWG that's brand new this spring as is the entire pool. The last 3 - 4 weeks we've been struggling with the No Flow light coming on all the time. I'm talking once every other day or so. The only fix is to backflush then it starts working again. The pool company came out and...

So I'm being told I have something called white mold in my pool. It looks like very fine white/light gray sand gathering in different spots on the bottom of the pool. It's so fine that it essentially dissipates when you touch it. It ranges from the shallow end to the deep end. We had it...

Here's the first of what will probably be many, many questions to this board. Our pool is new this year (started installing late fall) and frankly has been a complete nightmare. Most of it goes back to the installer but regardless we are where we are. Unfortunately I can't seem to get an...
