Hello. I am a new fish owner of a few months and I still know very little about the ins and outs of taking care of fish. I have a 55 gallon aquarium with about 12 fish in it, two of which are Chinese Algae Suckers. I have no live plants or rocks. I feed a pinch of flake food twice a day. A few weeks ago I noticed some green powder-like algae growing on my glass and rocks so I did a water change and siphoned the rocks and cleaned the glass with a tank scrubber. About two days after that I noticed more algae already growing again. It’s been about two weeks since the water change and the algae has seemed to multiply over night. My algae eaters aren’t doing anything to help it. I really need help, it’s getting to the point to where I don’t even want my tank anymore.
