Greenish tint

My water was perfect but I noticed my cartridge filter pressure was high so I needed to clean the filters. They were filthy. So bad I was surprised my water was clear.

I cleaned them and one day later my water had a dusty look and green tint.

Several days later still Greenish.

I keep my fc low.

Current values:
FC 3
CC 0
PH 7
CH 480 ( high for me)
TA 110
CYA 120

Suggestions? I use granule shock and tabs.

Welcome! You have come to the right place to fix your pool and keep it clear!

I am going to give you some links to read through.

These will get you started.

I would also like you to think about doing your own testing. There has been MANY people that use their local pool store for their testing. I am one of them with my last pool. In the end my pool ended up such a mess that the liner "rotted" out even with water in it from listening to the pool store :(

Pool stores "free" testing is not so free nor is it accurate.

The test kits we all use are listed in my siggy below. Since your pool is already green you will want to get the TF100 EL as you are going to need to SLAM your pool. Here is the SLAM link

Let us know what you decide to do.
