ugly stage

[jonwood]

I've had a saltwater aquarium for over 5 years, 2years ago I went from a 60 gallon to a 75 gallon. Both had sumps... had a minor problem with cyano bacteria about 1.5 years ago. That was quickly cleared up using chemiclean and doing water changes over the course of 2 months. Everything flourished wonderfully. However for the last month i have been battling dynos... and wow what a disaster it looks like... if any1 good give me some type of magical instruction to get rid of this mess that would be phenomenal! I have watched and read hundreds of ideas... but nothing seems to be slowing this down? Some1 help!

To clarify, after two years, the system suddenly developed this golden brown growth? The system looks lightly stocked.
