Brown Algea

[ktkreegs]

Two days ago, I cleaned the inside of my tank and did about a 10% water change at that time. When I cleaned out the water I took the siphon cleaner tube and cleaned off my crush coral.(it did NOT move the crush coral around and cause a dust storm) The crush coral looked like it had some brown algea on it and it was on the glass?

Lately I have been battling a green hair algea problem so I've been purchasing more clean up crews which seem to handle it ( i think i need more ).

My question is: When i got home from work yesterday, my rocks and crushed coral were covered with this brown algea. How and why?

Things to help you - help me:
- When I cleaned the tank, I cleaned out my protein skimmer completely. ( o yea the skimmer is a seaclone, with a ton of mods that i did to it, added wooded air stones, cut the riser tube down, different pump running it, it produces good gunk now)
- I added a mod to my maxi-jet 1200 (which added a ton of flow to the tank, very impressed)
- My light is a 250w 10k aqua medic
- only fish is a scooter blenny for right now
- and two corals, a gonoriah and green toadstool

IMO, Get rid of CC and put fine sand instead. CC traps detrius and this could most likely be the source of your algae problem.

Well, I can only guess that the cleaning stirred up some gunk, or something got tweaked in the system. The algae might subside over time on its own, if that's the case.

I didn't have much luck with crushed coral, personally, but the sudden change is probably related to the cleaning somehow.
