Help with sizing new filter

[TomC]

Thanks Watermom. He's going to get a pump/filter combo. What do you think of the combo in the link?

Thanks

OOPS. I didn't notice that it was a pump/filter combo when I looked at that link a few minutes ago. I looked too quickly and only saw the filter size.

See what Ben thinks. But, if it were me, I'd buy a bigger filter than the one in that combo. I've asked Ben to pop in to this thread and offer his opinion.

The 1.5 Hp pump is probably up-rated, meaning it is equivalent of 3/4hp full-rated pump, roughly, so not as seriously over-sized as a full-rated pump would be.

How to tell if pump is uprated or full rated?

[CarlD]

Usually the flow rates tell you. Hayward above-ground pumps (and this is one) are generally up-rated, but we have folks here who are more knowledgeable about such details than me. Hayward's combos do tend to match the pump and the filter, but just barely. Ball-parking it, I'd sooner see you get that pump with the next size up filter--the 200# version (T210?) and you'd be sure the filter is adequate. I don't know why Hayward doesn't match them that way, and the 150# sand filter with the 3/4hp uprated pump. I have the 200# with the 1hp 2speed Superpump and it's adequate at full speed, but I've always wished I had gotten the 250# (the Superpump 1hp is more powerful than the pump you're considering).

Still, a Hayward combo set should have a warranty on the whole thing.

Hi Carl,
Let me know if I should post this on new thread.
After 2 weeks out of town, pool is now slightly green from the vinyl everywhere due to pump working very poorly. I added a gallon of chlorox bleach and 4 cups of kemtek dichloro last night. Before adding, I've tried to vac the green algaes but pump kept beeping with low flow and self shut offed shortly. I have noticed that the pump had been losing the flow rate after the second season and now it's completely useless.

My current Intek has pump with SWG built in. Is it possible to buy just the pump connect it in series before the Intel so the SWG would still work. .

The intek worked OK when new but still very weak when adding 25 feet vac hose - it would beep for low flo and shutdown shortly. Vac hose attaching to intek skimmer is likely 1 inch....

I'd like a 2 speed pump and use hi speed for vac.

Please advise on my disaster situation?

Oh, boy! Not sure what's going on with your pump! You need to be able to test your water for us to recommend amounts. I would suggest only using bleach for now.

Oh my. He has a copper ionizer? Can you remove it? He doesn't want copper in the pool. If you can't remove it, take the cartridge/block out anyway. His sand is probably fine for now as it obviously is grabbing stuff.

Your more immediate need is to deal with the algae. You never posted test results so it's hard to know what to say other than turn the swcg off and use bleach to take the FC to shock level. Once chlorine levels are high, brush the pool all over and scrub every nook and cranny that algae could be hiding in. See the FC/CYA relationship here to know his recommended shock level:
