Water does not appear to be filtered very well

[leena]

I finally found some de powder and put 2 8oz cups of it in my skimmer. It immediately blew out thru the jet. Husband installed a valve between the pump and the sand filter but we not sure how to use it. Do we just set it to lessen the water flow by half, therefore not pushing the water thru the sand so fast? We have a 200lb sand filter with a 1.5hp pump. Do you think this is why it does not appear to be properly filtering?

It is probably just too strong a pump for the filter, pushing the stuff through it like you suggested. I would dial it down a bit and see if that doesn't help.

the pump is not able to be adjusted. there is no high or low or anything like that..........its just plugged in and goes at one speed. I will close the valve he installed, halfway and see if that does anything.............

Maybe try a Flocculant or Clarifier to help the particle clump and become larger to allow the filter to "catch" them ?

@ pratzert: If you have experience with a particular brand that has worked well for you, please mention it. We're trying to determine which ones work, and which ones just cause trouble.

Hi Ben,

I have to look when I get home to see if I still have the bottle of the stuff I used last.

But I've only ever had to use a clarifier twice since I've had the pool (12 years).

It did seem to work.....

thanks.
