I've this pool since new, about 10 years but I'm still learning. I have at least 3 issues noted below. Over the years, the walls have gotten significantly stained white. I have no idea next steps with this. It's not bad looking when full (until some evaporation occurs). I can actually feel...

I have a whistling noise and I'm hoping you can help me track it down and eliminate it. I've listened in different spots through a piece of 30" copper pipe to narrow it down and I hear it the loudest (with my poor hearing) on the metal piece at the inlet and outlet from the heater. I haven't...

Last year I took out my pump, taking photos of the wiring. Problem is I lost that phone and the pics. It's a 240v set up with a bare wire (obviously to green post). There is also black and white, I don't think it matters which goes to L1 and L2, can you confirm? Thanks

Hello, I have a noisy Master temp 400 making noises like the video in this thread; New Pentair Heater Broken - Rattling Sound, Trying to Diagnose My equipment is about 9 years old with the pump being rebuilt this spring (impeller was frozen, wouldn't turn at all). I'm not sure the extent of...

When starting my pool after winter, I turned on the pump and there was a clunk and an over current light. I ended up disassembling the motor and found that I cannot even turn the fan end. The impeller itself seems ok. Can you advise my of my next steps? As an aside, I checked the water...

Hello, My Master Temp 400 kicks in, I smell gas and hear the pilot trying to start it. It tries this a couple times and eventually gives the service heater LED. When opened up, the only alarm LED is LED 11, which I believe to be service heater as well. I've seen another thread which...

Hi My TA is a little high and not dropping. I've brought PH down but unsure how to follow up. Also, being in Canada, is Windsor Ice Melt what I should be using to increase CH. I've added a couple times but not getting the CH increase I'd expect. The label says Sodium Chloride CAS #7647-14-5

When I took the cover off my pool, the dry portion from the normal water level to the drained level is highly discolored. Please see the pictures. What could it be and can it be fixed?

I recently switched from using liquid chlorine in my tub to tablets. Yesterday I used non chlorine shock and since my ph was high, > 8.2 some muriatic acid. Today when I test, my Chlorine is 2 but my ph turned yellow!!??? Is this something to do with the shock or too much acid? Thanks

I'm in the process of SLAMMING after switching from Bromine to Chlorine. My CYA is about 25 and my target FC is around 12 I believe. All else was balanced prior to start using TF100. This is an outdoor stand alone SPA. Do I have to wait till the SLAM is complete and FC drifts back to target...

I just did my first test with my new kit. My noob readings: FC 7.5 CC 0 PH 7.5 TA 160 - 170 CH 180 CYA 30 - 40 The local pool store where I've had tests done till now list Alkalinity (with stabilizer correction) and recommend 125 - 150. Is that what I'm measuring with the...

My wife and I are coming to shop in the Niagara Falls Blvd, Sheridan Dr and Military Road areas this week. Could someone recommend a shop to purchase a test kit? From what I understand I should be getting a K2006C. Is there anything else I should be looking for? Thanks in advance.

After about 5 years, my tub cover waterlogged and the water smelly. Possible chemical burn as well. A new cover should arrive in about 2 weeks, what should I do to fully prepare for the new cover? My apologies if there's an existing thread on this. This is an outdoor tub that doesn't get a...
