I'm finally seeing some major progress with the HA in my tank. I was naive enough to think that my tap water was safe enough to use but unfortunately I learned the hard way that it wasn't. I've started using RO water and started seeing quick progress. That and limited daylight have vastly improved my tank. Here are a couple pics of my tank 1 month ago, and then this week. I would like to thank everyone on this site for opening my eyes to RO water! It's a lifesaver!
