New Tank, some filtration questions

Here's the tank as of today.

 

Here's my progress thus far.
Late last year, I started to get some hair algae in the display. I purchased 4 emerald crabs, some chaeto for my fuge, and changed the lighting so that actinics are on longer than the daylights. Hair algae problems solved. Turns out that I started to lose some fish, I solved that by removing the emerald crabs. Now I have an algae free tank, with fish that don't disappear.
For now, I have a purple firefish, blue chromis, red head goby, yellow tail blennie, and 2 sexy shrimp.
I had a galaxia coral that was getting nasty and stinging things, so that peice is gone. I've replaced him with some acans. I've also had to trim my xenia multiple times.
Now my new problem, which I'm sure I know the reason behind. My chaeto is growing very slow, and getting red slime on it. I'm also getting a lot of the slime in my sump. I've started using activated carbon over the past couple of months, and through my research I see that most carbon gives off phosphates. Today I've removed my carbon and gone back to my original, chemipure elite.
I do water changes every ten days.

Here are some recent pics of my display tank and it's inhabitants.






The duncan is one of my newest frags, I bought one head, it now has a total of 3 babies growing on it.








I moved the gorilla nipples, they stopped opening when the watermellon zoas encrouched on them, they still aren't opening, so you cant see them in the pics.






My blue green sympodium with the daylights lights on.








Blue green sympodium with actinics only.

 

Looks Awesome man!! Can't wait til you start fragging and selling!!!

 

Cyano has spread into much of the sump. It's also began to spread onto some of the rocks in the display. I purchased a turkey baster and blasted it off the rocks in the display. My tests come out perfect and the tank is very healthy. I started a thread about it in the algae section.
