Sand filter/pump question

[Steve V]

Well my pump gave up the ghost last fall. It is a Sparco 2hp 2 speed pump. We only used it on low speed. I also have 22inch sand filter..also Sparco. It does send sand into the pool at initial pump turn on.

My thought was to replace the filter also since I need a new pump anyways. Pool is 24 round 4 ft deep approx. 10000 gals. What sand filter/pump is recommended. I've been all over ebay amazon and decided to come here to ask before I pull the trigger.

Thanks

I am ready for pool season!

2 hp for 10,000 gallons! Was it up-rated or full-rated? Either way it seems 'way too big for your filter and pool. I would guess that you shouldn't have more than a 1 hp up-rated or 3/4hp full-rated pump for that filter, assuming it wasn't damaged by too big a pump.

For comparison, I have a 200# sand filter (yours is about 15#) and I run it with a 1hp full-rated pump with a 19,000 gallon pool!

Thanks Carl! I will look today. I need to order on tonite as I want to open the pool next weekend

Sorry..I had a typo--I meant to write 150#, not 15#. Good luck with it! Just remember it's better to oversize your filter than your pump, especially sand filters. I can't think of any reason to have more than a 3/4 hp pump for a 10k pool unless you're going for a 2 speed you intend to run on LOW. If I were doing it all over again, I'd get the same pump but get a 250# or 300# sand filter. BTW, my sand is the original sand...sand works better as it gets older.

Pool has been up and running for about a week. I bought a Hayward 18in #150lb filter. Used sand from Home Depot. It has been running almost a week and water is almost clear. Been keeping the FC above 15 CYA is 30-40 PH 7.4 so far so good. Gotta vaccum it this weekend and temps is already 74! Once I get it right how many hrs a day do I need to filter? Day or night better? Thanks

The object is to turn over the water at least once a day. That means running 10,000 gallons through your filter. It all depends on how many gallons a minute are being pumped through. But usually 8 hours / day seems to be enough.
Lots of people have different opinions on day vs night. Day, when people are using it, keeps it cleaner when they are using it. Running it at night distributes the chlorine better without UV breaking it down.
