not good...

[Christs_Knight]

Hi,
I have a 4 foot tank that has been running for around 7 months now.
I have never had ne problems, but just now my tank looks shocking!
its only 14" deep so i have a compact fluro on that pumps out more than enough lighting.
my corals have always been good, but now they looks bad...
I really dont know whats going on.
Algea is covering the floor everyday, i need to move the sand constantly. Also the waste from the fish is not breaking down, its just breaking apart and turns into mass builds ups.
I dont know what to do.
I dont have a sump, should i grab a Cannister filter.
I need help
