Hello everyone. Newbie here!…. I was hoping someone could help me. This weekend I did a 80% water change in my tank, because EVERYTHING was cover with a yellow/brown/gold buildup (algae??) I took everything out and cleaned the inside. I scrubbed my rocks until they were almost back to white….. I got everything back in, and refilled with salt water from my lfs….. now, only 2 days later, the build up is starting again . Any suggestions on how to get raid of it???? (I don’t want to let it be, and have to empty it again!!! Thanks in advance
