Hey everyone, my freshwater aquarium is having a horrible algae problem. Sometimes it get so bad that it grows on my live plant. The algae also covers most of my substrate. It literally grows everywhere. I do weekly 40% water changes but this doesn't seem to help. I have a canister filter that is rated for a 170 gallon aquarium and mine is only a 60. I use clearmax in my canister filter to remove phosphates and only use aquarium water to clean out my foams. I have an LED light that i orders off amazon that is the full width of the tank. Is it possible that this light id to bright?? Also i do not have a CO2 system and use Flourish Excel or API CO2 booster as a CO2 supplement.
