question about unicel 4607 filter fit in summer escapes pump

[singingpond]

Hello again.

I don't yet have new information to offer on this thread, as to whether Unicel filter makes a good seal in Summer Escapes pump...

I tried to start another thread with my new question (below), but the forum wouldn't let me do that, even though I tried to start the new thread in the 'Getting Started' area -- not sure what I did wrong... ?

Anyway, different, albeit related, filter question:

Reading in another thread (http://www.poolforum.com/pf2/showthr...ump-and-filter), I saw the following comment by user mas985 --
"Cartridge Filters: Most energy efficient and don't require backwashing. Best suited for areas with water restriction, high electrical rates and/or pools that use a SWG. But make sure it sized for at least 1 sq-ft for every 100 gallons of water."

We currently have a 1000 gallon Summer Escapes pool set up (10' x 30" size). We recently purchased a larger Summer Escapes pool (18' x 48", ~6000 gallons), but haven't set it up yet (we have to level a lot more ground first). Out of curiosity, we hooked up the pump (1500 gph) from the new pool to our existing pool, in hopes that filtration would be better. I can't really see much improvement, if any.

Looking at filter specs for the 1500 gph pump, the cartridges are described as 5 sq. ft. in area. If the above quote is accurate, filter area for our existing 1000 gallon pool should really be 10 sq. ft., and for the future 6000 gallon pool, filter area should be 60 sq. ft. That would mean the 6000 gallon pool is being sold with a filter that is about an order of magnitude too small... From reading about Intex pools on the forum here, I realize the Intex-type pools are sold with inadequate filtration capacity, but hadn't realized it might be quite this dismal.

Can anyone comment on these numbers -- is it true that we should ideally have closer to 60 sq. ft. of filter area to keep 6000 gallons of water clean?

Murky water is a problem we've had repeatedly during the several summers we've run the smaller pool; so I'm worried the problem may get worse with the ratios in the new larger pool (6 times as much water, and only about twice the filter area). We've been using the original crummy filters with the 1000 gallon pool all along; I sure hope switching to the Unicel or Filbur filters will help compensate for inadequate filter size...

Maybe I'm misunderstanding the 1 sq. ft. per 100 gallons number... does that properly refer to the pump throughput rate (i.e. 1500 gph in our case), rather than to the pool volume?

That would still mean that a 5 sq. ft. filter is undersized for a 1500 gph pump, but it isn't quite as bad as comparing it to the 6000 gallon pool volume (only too small by a factor of 3, not a factor of 10+).
