Hey guys so I have a question. I keep getting algae growth in my tank. It grows on some on my rocks and on my glass. It seems to be growing on some of my corals as well. It's a green algae. Just makes my dt look horrible. is there any input or thoughts on what might be the problem. I have been using just tap water so I don't know if that could possibly be a problem. I really have no where to get ro water and trying to buy a ro system right now is kinda to much for me (unless I am able to find a decent priced one). Any ideas or suggestions? Thanks
