I have to agree with the rest about getting inverts that might eat the algae. I have two urchins and a bunch of snails that do eat it and I can see them eating trails through it. BUT, the cyano
grows faster than they can eat it. I have reduced feedings to every three days, and this weekend reduced my lighting from 10 to 8 hours. I also have been using a turkey baster to suck it up and those methods seem to be working, so far.
I used to buffer my tank, but through reading, there is generally a chemical free way. Think of your tank as an extension of the ocean. The key to the hobby, IMO
, is keep my tank as natrual as possible.
For example, I was having a problem with my pH. I removed my canopy and upgraded my lights to over the tank lights and adjusted one of my PHs. My pH rose and is now stable.
