    Intex better than sand filter?

    We moved into this house and they had a 22' x 52" intex pool with a 2500 gal/hr intex cartridge pump & filter.

    I didn't think it was doing the trick and I didn't really know much about flow rate and that kind of thing, just that I had had pools before and it thought these intex was inadequate.

    I bought a used sand filter and a 1 hp pump that has had some issues with leaks and debris coming through the return.

    While working on my sand filter, I had to hook up the intex filter... And I have to say, I like it a whole lot better. It doesn't leak, the connects are modular and don't require modification.

    There are many intex users here, what do you think about these cartridge filters? Are they really adequate for 5 bathers a day? Pool season starts this weekend!

    An Intex cartridge filter is not going to work at all well for a pool that size. We have had large numbers of posts from people having problems with those filters.

    I agree. I owned a 15' frame and an 18' easy-set and had difficulties keeping them clean with the intex filter.

    At one point I calculated the area of the filter and came up with something around 15-20 sqft. That isn't going to cut it with 5 bathers in a 10,000+ gallon pool.

    Is the issue the filtration? Because At 2500 gallons per hour that's not too far away from a 1 hp Hayward pump is, is it?

    The pump is fine, it is the cartridge filter that is the problem.

    I saw some at the pool store that said that they last "all season long" Is it possible to buy a better filter?

    Any filter is better than an Intex cartridge filter. The most affordable filter would be an Intex sand filter. A 19" sand filter would be even better.

    Re: Intex better than sand filter?

    The second best thing I've bought for my pools is the sand filter/pump combo. I use the pump that came with the filter to get the water flowing in a whirlpool, it helps get the dirt to the middle of the pool which makes it easier to clean up. This is our 3rd "temporary" pool, and ALL of the pumps/filters that came with them were pathetically sized for the job. Go with the sand filter, you won't regret it- modified connections and all.

    Not even a unicell filter will do the trick eh?

    Yes, that filter is a good deal and reasonable for your pool.

    Thanks- I did buy that and hopefully it will do they trick. For some reason it is only a 2100 gph pump.
