Another green cloudy pool

[hulla]

Yes, I got the high chlorine test kit from Leslies. It says it tests from 0-20ppm. It comes with Taylor R-0870 powder, R-0003, and R-0871 FAS-DPD. Will this test past 20ppm?

I am brushing at least once a day and running the filter constantly. I can't backwash since I have a cartridge filter and no backwash valve.

This morning my chlorine tests at:

FC 21
CC 0

I will keep putting in chlorine.

Thanks for the responses.

Now my pool is clear blue. It is pretty but looks like food coloring. I can see the pool floor and drains fairly well now.

Is this the end point? Or should I keep the chlorine up until the blue goes away?

My recent experience and ample gut tells me that you should maintain shock levels until your water looks "right". I just went through a similar process with a cartridge filter. It's tough. I wanted to SHOOT anybody that uttered the words "... and then vacuum to waste".

One thing to remember: Keep your eye on the filter pressure. You are pushing a LOT of dead algae through there. When I was in the throes of my algae battle, I was cleaning the filter elements twice daily.

Hang in there. You're in the home stretch.
