Green Algae on the wall

[mer33]

Here is my current readings
Free Chlorine - 3
Combined Chlorine - 0
PH - 8
Total Alkalinity - 80
Calcium Hardness - 230
Cyanuric Acid - 40
Temp - 85F

Water is crystal clear. I always use 12.5% liquid chlorine and maintain FC around 4 PPM.
But every 2dn or 3rd day I see a light coating of algae on the walls which I need to brush.
Do you suggest SLAM to get rid of this?

You'll need to SLAM and then maintain your chlorine a little higher in the target range which is 5-7ppm if you're getting algae at the minimum level.

Edit: when you say 2nd or 3rd day, does that mean you're not adding chlorine daily?

Thanks. I will start the SLAM today. No I keep adding Chlorine to maintain it at 3 to 4 PPM.

Great. The SLAM will give you a fresh start. Then, as long as you keep your FC in the target range, and not let it get near the minimum, it should be smoooooth sailing.
