after things settle you can ditch the bioballs and add rockrubble

I only said over feeding because the same thing happened to me when I added a pair of clowns to my 8 gal BioCube which was primarily a macro tank that I had up and running for over 6 months with ZERO problems...as soon as I added the clowns I started getting cyano algae all over the place....but cutting back feeding was not an option because they were babies....so I increased water changes.

Once the fish were gone, the cyano went away. I was feeding twice a day....which is overfeeding in a tank that small.

Pretty much "daily feeding" is "over feeding" in a stock 8 gal biocube...unless you have some mods and/or a sump working with it coupled with frequent, consistent and sufficient water changes.

yeah i need to get rid of that clown he does eat to much.
when and how much of a water change i need to do mr cob?

[FireWater]

My opinion is back to back 2 gallon changes. 2 today and 2 tomorrow. When you do the water change you need to try to siphon as much of the crud out as possible. Smaller tanks can be difficult to keep stable. All of the mods that have been mentioned are great things to add in a little at a time. Are you able to get any pics? And have you tested your water that you adding with the top offs?
