I have a ton of hair algae as well as algae on the glass. The issue wirh the glass algae is it’s really on there even my magnetic scraper can’t get it off unless I go back and forth on the same spot for over 10 min straight please look at my photo and give recommendations. I understand Ultimately it’s a chemical balance issue but I want to build a cleanup crew that can visually clean it immediately after that I will monitor the chemical balance in my tank and maintain a good and healthy one. Might think it’s 20 gallons please give me recommendations I already have one emerald crab and one snail that goes on the glass and one hermit crab but it’s definitely not able to overcome as you can see from the picture
