I was on vacation for the past week or so and when I got back I noticed from green algae on my light and fixture. I put pucks in while I was gone and tested my FC about 2.0 when I got home. Probably a little low for my CYA of 45.
I brushed off the algae.. I tested with my kit and got 3.5 FC, 0 CC.. (I added some chlorine) Should I still shock because I saw algae?
