My 180g has a lot of built up dark, green & brown algae in the overflow box in the tank. My nitrates are high, all other levels are normal & salinity is 1.022 but I just added 5g of freah 2 days ago so I’ll bring that back to 1.024-1.025. I want to dig out all the clumps of built up algae that I think is slowing the water flow but not sure if it will unbalance everything else or not. Its like a good fist full of algae sponge. Suggestions? I need to get my Nitrates down they are really high!
