Two qustions

I never used a power washer, but we do shoot it with water at high speed to clean it - maybe we messed it up. No backwash.

The reason I'm trying to verify the pump thing is that we have had this pool for 10+ years without much of a problem. It seemed like my husband put a bottle of some kind of "Low Chlor" ?? stuff in every 3 months & kept the chlorine from the pool store in it & it was almost always clear. Then we drained it & replaced the liner & refilled. Changed cartridge at the same time, had a pool guy for a month or so & left most of the summer - so there are a lot of variables.

For the last 2 1/2 months we've been battling green & cloudy endlessly. So, when I go tell DH it's too strong of a pump - he wonders "Well, we never had a problem before......" That's why I was trying to brainstorm other ideas before making an investment in a new filter or pump. $$

How would I know if it is "plumbed wrong"? Thanks for the ideas,

Jennifer

If you've been "battling green & cloudy endlessly", it's because you're not properly maintaining your chlorine levels, and has nothing to do with your pump/filter problem. However, it's possible that you just have never had enough of a dead algae load on the filter to notice it blowing back through to the pool until now. I don't have a cartridge filter, so I'm not the best to give advice on them. However, all the pool owners I know that DO have them can replace just the cartridges and not have to replace the whole filter ( unless you're ready to go with sand or DE, which are much easier and more efficient to deal with). Try replacing the cartridge. If the cart is bad, that will fix the blowback problem. If the problem continues, then I think you need to be looking for a much bigger filter or smaller pump. I have a 1 HP pump on my 29K gallon pool and it is more than enough.
