I have a 125 gallon tank thats about 5 months old thats growing into a mixed reef tank. One of my earliest fish is an algae blenny/lawnmower blenny. It was purchased to help control algae however its come to have the opposite effect. It wont eat any foods i have tried to feed it and only eats the green algae on the rocks and sometimes the glass. My daughter loves this fish because its ugly/different and i want it to stay healthy. So i started increasing my lighta and letting algae grow. I just got my hanna phosphate checker and measured 0.41ppm. I am reading that this is very high and will hurt corals and cause algae problems. I was wondering if experienced people had an opinion on whether lowering my phosphates down to .1 or lower would be a good idea. Less algae or at least keeping it at a controllable level and coral growth are both important ideas to me. How much does the algaeblenny really need. He looks kind of fat now too but i dont know if thats normal. I am thinking of installing a gfo reactor. Any info or opinions will be appreciated.
