This week I changed the light on my SW tank and also added another pump that I had laying around. The light is an AI Prime 16 HD, I tuned it based on BRS AB+ standard at about 70 percent intensity. I am giving it about a month to get to 70 percent. What I noticed is that the algae bubbles has stopped; maybe the new light is not so good for algae. I hope so! The new pump seems to be working, for now. I would like to get another small DC pump that I can aim. I will keep my eyes out. Planning for the Hydros controller not sure if I want to move over to it, but it was a very good deal and I need to see my PH. It is something that can grow with me.
