About a month ago i had a red slime outbreak in my tank. I am away and my wife is takeing care of it. With the stuff she got to kill the slime the guy to ld her to out a airstone in there. and he said that she could leave it in there after it cleared up. I guess the naked clowns like it. Is there anything I should be worried about it being in there. Never seen one in a reef tank before.
I absolutely see no reason in adding an airstone to counter cyanobacteria at all. None what so ever.
Take that bio cube...second chamber where the grill is with bio balls...Take out all your bio balls...nitrate factories ....replace them with rubble live rock instead. At the same time buy filter pads and cut to fit under the grill over the live rock rubble.
My mod advise for you. I had the 29g for a year. So I know what you are dealing with. The filters from oceanic easily restrict flow just from dust kicked up by stupid fish or something.
Sorry I just went over this red slime thing in another thread...but Red Slime appears for only one reason. Enough Nutrients to grow from bad water chemistry. Nitrates and Phosphates are the causes.
You need to do siphon of all visible slime and do a 50% water change in the process of cleaning. (Do not brush slime it only spreads the bacteria)
Then after the big clean up and 2nd chamber changes...you should have better conditions. Slime will appear but not fast or growing fast. YOu must keep up on weekly water changes of 50% or greater (being a small tank this will be easy).
Biocube lacks protein skimmer so you are more reliant on old fashioned water changes. To prevent fast build up of nitrates. Practice feeding lightly. Food should not be floating around 5 min later in other words.
Prevention is key here:
1. weekly water changes of 50%...or 1g a day ...
2. Top off with quality water source that is nitrate phosphate free..RO/DI water for example.
3. Lightly feed
4. Keep photo periods in general not over 8 hours.
You should be fine if you do this from here out. With lack of information this is just general info for you.
