Hello! My 75 gallon planted aquarium has been running for about 2 months+ and in the past few weeks, we've had a growing brown algae problem. It's growing on the glass, substrate, driftwood, and all of the plants. All of our plants are live and as for fish there are 6 juvenile discus, 4 orange lemon tetras, 10 cardinal tetras, 5 panda Cory Cats, 2 loaches (don't remember species), 1 Apistogramma Trifasciata, 2 little ghost shrimp and a few little snails. We've recently started feeding 1 cube of Beefheart and 3 cubes of Bloodworms twice a day. My guess is the excess food and waste, resulting in Phosphates, are the problem. I'm so confused about what to do. My partner and I don't want to use chemicals, and we've tried just pulling the algae out (there's a LOT and it keeps growing fast). Please help. This is supposed to be our "decorative" tank. The tank is in our living room, and we used to enjoy looking it it. Now it just makes us sad.
