Friends, I just had to replace my old Pentair #340210 1.5HP pump (see this thread if interested) connected to my Sand Dollar SD40 sand filter. Thankfully, the inlet plumbing and base alignment is perfect and needs no adjustments (sigh of relief!!) Unfortunately, the 2-1/2" OD pump outlet has...

Friends, this motor/pump came with my SD40 filter 7 years ago, and I replaced the motor/pump 4 years ago after the first one was flooded (that's a long story.) It's a single speed pump and has been sounding a tiny bit noisy for the past 1-2 years, and has a very slight leak from the pump some...

It's been a long time since I posted. A few years back, I cemented a 1.5" to 2" PVC pipe adapter inside this ABS filter outlet on my Sand Dollar filter for my AGP. There's a union that connects to my salt water chlorinator after this. Today, it broke off (I'll spare you the details). It...

We had about 11 inches of rain over the past couple of days, thanks to Florence. Because our pool is on a sloping lawn and we didn't think through where to put the pump, it is on the uphill side and so it sits level with the bottom of the AG pool, inside a makeshift box to hold back the...

My 14.5K AGP came with a Pentair/SandDollar 1.5HP pump and sand filter, and my Saltron Retro SWCG died again this year after getting the cell replaced under warranty last year. I just purchased a CircuPool SJ-40 generator and intend to plumb and wire it myself. Unfortunately, although I have...

We got our AGP two years ago, and the Saltron Retro over-the-edge SWG has died twice now -- thankfully the first time was under warranty. It was under-sized anyway, but did the job. I think it would be best to go with a higher-output (but preferably adjustable) inline SWG, and would love some...

Yesterday, I tested our AGP and discovered that the FC had mysteriously dropped to 1.5 and then realized that our over-the-edge SWG had stopped working -- I guess I should have been paying more attention. :-/ pH was 7.6, TA was 60, and CYA was 60. Based on the low FC, I assumed a high risk of...

Friends, We have a cloudy pool and I am really not sure if it is algae problem or a filter problem. Here are the facts that have me puzzled, starting with a picture: The back-story is that we went on vacation for a week and had our neighbor starting up the pump and SWG in the morning and...

Friends, This is my first opening. Peeking under the cover, the water looks clear, thankfully! In reading here, I see that the general advice is to use chlorine shock to bring the FC level up to 3. I am probably missing something stupid, but why wouldn't I just use bleach in addition to my...

Our summer is about gone here in Charlotte, and the leaves and pine needles have started their downward journey towards the pool. It means increasing amounts of time cleaning the pool and our swimming enjoyment has dwindled to about zero. I read in pool school that you wait until the water...

Friends, Brand new pool owner here. Details in signature. No issues yet -- the water is clear, warm already, and my family is loving it! Waiting on my Taylor 2006 test kit to arrive tomorrow, but here are some pool-store tests from yesterday: FC 3 TC 3 TA 45 PH 7.2 CYA 70...
