I have a s166t sand filter (100 lb.) for my 24' ag pool. Everyone says I need bigger filter. Would a s200 (200 lb.) sand filter be big enough or should I keep looking for a bigger one, say 24" filter (300lb.)
Yup...what Bama said. I run a 22" hayward S220T (250lb) and backwash maybe 3 times a season....and that is not even because the PSI rose significantly rather I figure after a good storm and the pool topped off, might as well backwash
That said...if you are OK with frequent backwashing, you are on top of your chemistry and you do not have an algae outbreak...you're 100lb filter will do OK, but once you do have an issue that will require increased filtration capacity...you'll find the 100lb filter to be too small for a 13.5k gallon pool
I see both of the people that previously answered have different size pumps. I would like to only run pump 4-5 hours a day. If I get 24" sand filter should I keep my 1Hp. pump or down size pump and run a little longer? what will save more energy. I am on limited budget now and need to save where I can. Please help me out.
Have one silly thought, could I just add more zeobrite to my 100lb sand filter.(only put 50lbs zeobrite in per manufacturers specs.)would it work better or just cause problems. As I said just a silly thought.
If your going to invest in a new filter, stick with a quality pump...not saying that the pumps above may not be a good short term deal, but eventually it will need fixin'. Hayward, Pentair and Jandy are what your looking for.
For your pool (I have the same pool) a 0.5hp Full rated or 3/4 uprated pump is all you need...unless you want to go with a 2speed, which then I would suggest a 3/4 or 1hp pump. And you'll do just fine with a 250lb sand filter...although 300lbs can't hurt.
Is your pump and filter fairly close to the pool?
Also...please try to keep related topics in one thread as it helps us make sure we understand what your full set of goals are.
