Desperate NEWBIE needs help on Purchasing a new filter

[drumr]

I would probably just continue to use the 1 hp you already have. When I was looking for a 3/4 hp pump I was told the same thing by the pool store and they tried to sell me a 2 hp for my 200 lb sand filter. I ended up just ordering a 3/4 hp pump online and had no problems with doing that. Since I went from a 1.5 hp to a 3/4 I have noticed it filters better and my suction side barracuda ranger vacuum works much better too (it got stuck alot) it doesn't get stuck any more.

Hope this helps!!

Helps a bunch. I did not want to buy the pump, knowing the I have works fine, and sounds fine. I'm not familiar with pools, this is our first, but the pump and motor sounds pretty quiet and was working. So I will just go with that. THKS!!!!!!!!!!!!!!!

I have a AG round 24'x 4' deep. I believe that the volume is just under 14000 gallons. (If somebody could verify that I would appreciate it.)

To determine your volume, use the following formula:

Depth Ratio = actual depth (inches) / 48 (inches)

Volume = π * (Depth Ratio * 4) * radius^2 (cubic feet)

Then multiply your volume by 6.22883288 for Imperial gallons (used by BleachCalc) or 7.48051945 for US gallons.

I have a 24' x 52" AGP with a water depth of 46.5". Plugged into the formula gives me about 13100 US gallons. Yours should be less, since you have a 48" pool. I'd imagine that your depth is around 42". Using that, you would have about 11800 US gallons.

I may be wrong, but although the bleachcalc says Imperial, it is actually in US Gallons.

holy crap Raddish...Is that english? LOL. I don't follow, actual inches/ 48 inches??? I'm confused enough as it is, is there a laimans term for that? Sorry for being alittle empty in the noggin.

The bleachcalc can also calculate your volume for you!! (click on 'morecalcs' in the upper left hand corner to get calcs for pool volume and stuff other than bleach.)

I plugged in your numbers (24' x 48") and came up with 13570.56 gallons.

HTH

[rnjng]

wow, I never noticed the more calc tab, tks.

[GraceByDesign]

no problem!

However, I used 4 ft, your wall height, when I did your volume calc, NOT the depth of your water, so you will want to recalculate with your actual water depth!

Sorry for the mistake, it's too late to be doing this much thinking!

I got my motor for free. It was a hayward powerflo lx 1.5hp. So I got the C900 filter for it which flows 90gph. I have a new 18' round. I only have to filter for an hour, maybe two every other day so far and my pool is around 85 degrees right now. It does an awsome job. The pool is spotless really. I throw the barcudda in every other week. So far so good.

The filter is simple stupid and nothing to go wrong really. Everyone complains about the cartridge costs, but I see them on ebay for roughly $50. My uncle is on his 4th year with the two of his and they look and work fine still. I suspect in the long run the costs are in there with sand. I think they're easier to use, and they filter smaller particles appearently. How hard is it to hose it off two - three times a season? Plus....no water loss from back filling.

I'd get a C700 for that pump and go with it.
Just my two cents.
