My sad tank

[coolhandgoose]

My tank has been going downhill steadily for the last two months and I'm thinking the cause may be the fact that I haven't replaced the filters in my ro/di. It now reads a tds of 30! So even my top off water is adding to the mayhem.

Here are some pics let me know what you think. I'm thinking it may be diatoms and some cyano and not Dino's like I originally thought.

And an SPS looking really sad, no polyp extension, you can see the green cyano in the background.
