Rust Colored Algea After Tank Move

Most likely cyano. I would just keep doing partial water changes to lower the nitrates. You might want to get a simple TDS meter so you can actually determine the quaility of the water going into your system. I know I had a lot of cyano when I was using tap water or fed too much on my first system.

Thanks for the replies guys. My new RO/DI unit actually has a digital TDS meter on it and does an online reference while producing water.
