Running out of POP!

[PoolDoc]

Yeah. A 3/4HP Super Pump is almost certainly over-driving a Tagelus 50D, which shouldn't be run at more than 35 GPM max. If you have an up-rate Super, you're probably running 40 - 50 GPM.

Tell me what your clean filter pressure is, and I can estimate it more accurately.

Clean pressure hovers between 11 psi & 12 psi. When I restart pump, I can check that against another gauge. Thanks!

[PoolDoc]

That would suggest you are running between 40 and 50 GPM if the pump is an SP2605x7, or between 50 and 65 GPM if it's a SP2607x10 . . .

Ok, so I walk out this morning....cloudiness is about the same. There may be a very slight difference, or it may be my eyes being optimistic. As to the pump, the model # C48J2N131B1 and the motor # SP-1605-Z1-M Service: 1.0.

I was thinking of taking a bucket of the pool water and adding floc to that (as a trial) before adding to my pool, to see if it would settle in the bucket.

I did some experimenting today. I hauled about 10, 5 gallon buckets to work with me. I work with fish. I filled 3 five gallon aquariums with my water, and hooked up a mini sand, DE, and cartridge filter. After about 6 hours, the DE had started to clear the water; the sand and cartridge will probably still be the same a month from now!. I tried a few different polymer pool flocs. I used one beaker with nothing added as a control, none of them did a thing. I had cultured for algae last week (just in case I hadn't shocked it into oblivion)...no algae in the pool water (or there wasn't last Wednesday, and I have maintained same cl level). I don't know if any of this will help. Is there a chance that an alum based floc would work?? I couldn't get my hands on any today.

Yes, but as you probably know, alum is 'twitchy' -- you have to get your CA high and your pH low (by pool standards) for optimal results with most particles. Polyaluminum chloride is more effective and less twitchy. I'd found some on Amazon, but it's not available, but I did some more looking and found that GLB Drop-n-Vac is an alum and PAC blend. You may want to try that:

I would recommend a jar test, first.

I'm trying to find some plain, high concentration PAC, but I'm not having a lot of luck.

Thanks for the link! It will ship out tomorrow or Wednesday; wasn't eligible for overnight for some reason...oh well. I've found some alum; gonna jar test that in the morning...should know something by tomorrow afternoon. Fingers crossed. I added half a dose of muriatic acid tonight to lower pH some...just in case the alum works. (pH -7.8) I am aiming for 6.9 -7.0. My alk is around 120 right now. Ca+ is around 200 ( I will get a definitive number tomorrow, very rarely test ); what would you recommend I target for Ca+? I know I need a sizable alkalinity buffer so the floc can hopefully work it's coagulating, floccing, and settling magic.
