IG 15K gallon pool with attached elevated spa with a spillway, built 2013. Full Pentair Easy touch system with a VS filter pump. When I am running the pump, with both my suction and return valves fully on POOL, I still get some return to my spa. Enough to trickle over the spillway (but not...

Pool built by previous owner, 2013. I have 2 pool lights and one spa light. One of my pool lights and the spa light are not coming on at all. Have only pulled the one pool light that is inop. It's part number 601002. 120V LED color light. Full Pentair system with the EasyTouch 8 box...

Been reading up on winter use of my ic40 SWG. Pool temp is now 58, which I believe is the cutoff for the SWG to stop producing chlorine. The manual basically says that's all I need to do unless I anticipate freezing temps. I'm not quite understanding how that relates to my use of the attached...

I'm having an issue of getting an airlock every 2 or 3 days in my cleaner pump. I have a full Pentair system built in 2013. I'm usually able to clear it is to take the inlet hose to the pump off. Water flows instantly, so I think the air is on the other side of the pump as it heads towards...

Took mine apart to clean today. Drain plug is very hard to reach, so shop-vacced out the standing water in filter housing. Is it normal to have about 10-12" of sludge in the bottom? Seemed like it was mostly DE.....pretty thick after sucking out the water. Just wondering if it had been over...

Please look at the pics attached. I have stone and masonry that abut the plaster in my pool....and is below the water line. Many spots have cracked or have holes where algae can hide.....no way to brush out. I've slammed my pool 3 or 4 times over the last 2 years. Each time, the OCLT has...

After cleaning my Pentair, I'm having an issue that I hope someone can diagnose. I suspect an air leak, but not sure. Recharged filter and everything seems to be working ok. The next morning, I noticed DE in my pump basket and my filter pressure was at ZERO. The pump primed and the filter...

I'm on day 3 of my SLAM for what I believe to be M.A. Last nights ONCL was 1.5, so I'm getting close to the end where I'm going to take it up to M.A. SLAM level for 24hrs. In the M.A. instructions, it says to brush everywhere (lights, steps, ladders, etc....) and it also mentions the floor of...

Apparently I was not successful with my first mustard algae SLAM last month. Quick question.... Is there any reason I cannot go straight to M.A. SLAM level instead of doing a normal SLAM first?

Getting ready to SLAM and then M.A. SLAM. Pool is clear, all my readings are good. Overnight chlorine loss was good for 2 nights in a row, yet I still get yellow on my walls if I don't brush the sides at least every other day. Trying to figure out where my algae problem is residing and I...

Convinced I've got mustard algae that shows on walls of pool after a day or two of not brushing. Although, when I've done the overnight chlorine loss test, I was consistently under a 1.0 loss. Water is clear.....just a pain getting the yellow off the walls. My CYA is 55, which will put my...

I started with a CYA over 100. After draining and refilling about 3/4 of my pool, I'm down to 55. Stopped using the trichlor tabs, and want to wait on my water bill to see what a 15,000+ gallon drain and fill is going to cost me before getting the CYA a little lower. I had a small algae...

OK.....here we go. Time to get serious about keeping my pool in balance. IG 23,000 gallon pool. Manual chlorination (chlorinator with tabs). Reason I found this forum and bought my TF-100 was I can't keep chlorine in my pool, even with the chlorinator at it's highest level. From what I...
