Well it hasn't been quite a month yet but I'm getting algae growth again. It's been raining for 40 days and 40 nights it feels like. Right now my FC is 3.0 and CC is 0. I just opened the housing to see the filter since I last posted and the image below is what I found.

The psi is still at 4.

Also, I'm not sure on how often I'm supposed to add chlorine or the proper level. I've been adding a bag of that shock plus every 5 days or so until it's all gone and then I'll purchase something else.

I'll pick up 6 gallons of bleach again and put it in tonight unless I hear otherwise.
