A few weeks ago I asked if my DE cartridge in my Sta rite PLD50 filter was causing low flow. I soaked the cartridge and ended up replacing the it (very expensive) and that wasn’t the problem. Still have low flow to sometimes no flow. There are no blockages. I’ve checked all lines and the...

I currently have a Sta-rite PLD50 filter on my pool. Not sure how old it is but we’ve had it for 3 years and got from a friend. The cartridge needs to be replaced but I’ve seen $260-399 for it to be replaced. Should I replace it or switch to a different filter? There is no backwash and I’m...

I have an above ground pool and I'm confused about Ch. it was 200 at the beginning of the season which was within range. Now it's 160. Do I add anything? I've read in a vinyl pool it's not something to worry about. But just wanted to check.

My pool has been running and clear for the past few weeks. The other night I noticed it was cloudy, added extra bleach to bump the chlorine up to 6, cleaned the cartridge filter and ran the pump for 24 hours. Pool was no longer cloudy. This morning, I noticed what I think is some algae...
