Equipment Info and Runtime

Hey All,

I wanted to find out some info about my filter/pump in regards to its adequacy in relation to the size of my pool. And based off its specs, how long I should run the system for. Had an issue with algae last year and do not want it to happen again.

Pump - Proline/Speck-Pumpen - PE71-II-V - 1.5HP SPL
Filter - Waterway Clearwater High Rate Sand Filter - 22"
Max Flow Rate - 55 GPM
Max Working Pressure - 35 PSI
Sand - 150 LBS
SqFt Surface Area - 2.64

Pool - 24ft Round, ~14k Gallons?

Thank you!

The existence of algae has little to do with your pump or your filter but is usually caused by a low chlorine level relative to the CYA level. Post a full set of test results, including PH, FC, TC, TA & CYA, so we can see your current status.

I understand that. Currently in a shock cycle as I just reopened to a clear pool. I don't have a full test kit either, only red/yellow.

This post was more mainly to double check that this pool package we had installed is adequate.. meaning not over/under powered. After vacuuming dead algae off the bottom of the pool last year, only to see it blowing straight back in from the return port, I worry that the filter is either too small, or the pump to large. Or if there is too little/much sand in said filter. Don't believe the pump is 2 stage-able so im just trying to cross things off in my mind to make sure chemicals are the only thing I need to worry about this season.

AG pump size is very hard to gauge based upon just the motor label. But a 1.5 HP SPL is the equivalent of a 1 HP up rated pump which is equivalent to a 3/4 HP full rated pump. Add to that the fact that AG pumps usually have lower head curves, your pump is probably not all that big for that size filter so I would say you are probably ok.

The issue you are seeing could be due to either the filter or the debris you are trying to filter. Most sand filters are suppose capture particles greater than 20 microns but some algae is smaller than that and can travel through the filter. One thing you could try is allowing the filter pressure to rise more before cleaning as that will help to capture smaller debris. Also, I think some people have successfully used DE in sand filters to help with debris capture but I don't have any experience with that.

What is SPL exactly? I know it as Sound Pressure Level from my car audio days.

I was going to try the DE addition if it happens again, but heard horror stories of it blowing straight into the pool and being a bigger mess. Last year I was just vacuuming to waste basically while having a hose running into the pool.

I had a pool company come to my house and do the vacuuming last week.. He brought his own pump and a cartridge filter.. seemed to handle the algae on the bottom just fine. Could always find a used cart filter for that purpose. Pool guy said I should really just look for a better sand filter, a Hayward is what he recommended. But figured he was trying to sell me something.

Since nobody is replying with a "OMG you have that filter/pump.. no wonder" it at least puts my mind at ease enough not to worry about it.

SPL is a term Mark's using to refer to the AG pool pump ratings. I also need to ask him about it.

ONLY use DE to test your filter to make sure it's working: if it blows through the filter, you know your filter needs repairs (maybe, sand).

We need to back up here: it sounds like you may have been asking about your pump / filter combo, because you have an algae problem? If so, spin that off into the Algae section, post your test results, tell us whether you have (or have ordered) a K2006, link back to this thread for equip info . . . and then let us deal with algae THERE, instead of here.
