do those people who have a bb tank do you scrape the coralline algae of the bottom glass or not

wish I had that problem!!!

no, thats what you want. The difficulty I had (a while ago now )was when to stop scraping diatopms/green hair algae so the coraline could grow

I have just atrted putting a few corals into my fish only....I am having difficulty getting the phosphate down, I have sea gell in the filter, and have tested the rain water which has no phosphate in it, and my other reef tank is all good. I have got the brown stuff on the rocks again and the bits of coraline are slowly going white. Calcium and alkaline all good levels....my light is not that good though and will be dealing with that on tuesday when the part arrives to hang it from the roof...I've been waiting about 6 weeks now...I sent it up for a "service" and it was returned to me minus a part!!!! :evil: :evil: :evil:

Just cover it in sand and you won't have a problem
