How long does it take cartridge filter to clear up water upon opening?

[beandance]

We are opening our pool this week and the cartridge filter has been running 24/7 since Tuesday afternoon. The water is still a little cloudy. How long does it usually take to clear up? I feel like the past two years only took a couple of days. The water was especially green and dirty and smelly this year upon opening. I hired a company to do the opening for me so I haven't tested the water yet this year. I usually start testing after they open it and then I maintain it from then on. Thanks!

Hello and welcome to TFP! Sounds like you have algae in your water from winter closing. It's time to perform a SLAM via the link below in my sig. To perform a SLAM you must have either a TF-100 or Taylor K-2006C test kit to test FC levels at a higher required level. Do you have your own test kit? If so, please post those numbers.

A "SLAM", using the proper ratio of bleach (FC) versus stabilizer (CYA) will be the prescription to make you water clear again. Filtration alone will not do it. Let us know if you have any questions. We'll be glad to help.

As Pat states above you probably have algae in the water. That is a chemistry problem not a filter problem. Have whoever is opening your pool come and look at it. They should deal with the algae.

Welcome to TFP!

Filters don't kill algae, chlorine kills algae and then the filter grabs it. Until you kill all the algae with enough chlorine it will just keep growing more and more. As TS says time for a SLAM to kill the algae. You will have to clean your filter quite a bit because algae clogs up filters fast last time I had some algae I had to clean the filter every day or two.
