Hi all. I have a StaRite S8m150 pool filter on a 1hp pump, 30000 gallon pool.

I’m having trouble with suction. Have tried cleaning filters (450 square foot filter media) and even did an acid bath. I get a temporary increase in suction. Sounds like the filter media needs replacement.

Cost to replace is about $750.

At this point is it better to replace the filter? Go sand…. A different cartridge model. Pool came with the house when we bought it so the setup is from previous owner.

I live in Ct so have the pool open about 3-4 months.
 
Good morning and welcome to TFP! :wave: Before you do anything drastic like replacing a filter, let's discuss your main issue - reduced water pressure. It increases temporarily after you clean only to slow down again right? Did you know that's a classic sign of excessive organics in the water? Even what appears to be clear water? Much more common than you might think. How about we start by seeing a full set of water test results to make sure it's not organics causing that water restriction issue? We recommend posting a full set of water test results from either a TF-100 or Taylor K-2006C.

One question for you .... did you give your filter cartridges a good detergent bath before using the acid?

How old are the cartridges? If you gave an acid bath without first removing any oils, the cartridges will have very short filter cycles.
