Welcome @Theo2012 to R2R.

Let's start out by finding out a little info.

How old is the tank?
What are your parameters...specifically nitrates and phosphates?
Are you using RO/DI water in your tank?
What do you have to export nutrients....skimmer, water changes, refugium, carbon dosing, etc?

Welcome to R2R! Happy you're here and I'm sure you'll find the answers you seek.

Welcome reef2reef. Like @redfishbluefish we need info about your tank to truly help. I would like to add to the list

What are the lights your using and how long you are running them.

The stuff on the back wall kind of looks like a type of cyano that appears brown and fuzzy rather than the usual red slime, but a whole lot of it.

 

[Theo2012]

Nitrates is 0 ppm. The tank has been running for a little over three years. I use pre mixed water from Petco. With water changes every two to three weeks. I use RO to top off. The light is not sure I got it from a friend. And my salt level is in between 1.028 and 1.030

Yea it is brown an you cant scrub it off I have tried with a stiff plastic bristle brush

Are you tracking phosphates? Also, how are you measuring your nitrates? How much and of what are you feeding?

Small tanks can be tricky. Too much food.... from fish that sometimes look like they are "Starving" can wreak havoc on your nutrients. You may think about reducing by 2/3 the amount you feed. It shouldn't impact your clowns. Also, how long are you running your lights? I don't see a lot of coral... If you don't have a lot, reducing your light period may be helpful... if no corals, even a period of blackout could also help.

Get your salinity back to an acceptable range for starters. 1.026 maximum. RODI is really important, ro doesn’t cut it. We are here to help.

 

[Theo2012]

The light has a solor cycle and a moon cycle I only have a small amount of coral. I am sure this is bad but I have never checked the phosphates

Do you have a LFS near you? Bring them a water sample. I’d do a 50% wc and add some RODI to get back to 1.025 and just back in range with your macro elements since you have coral.
