proper flow for a 30 gallon??


I just bought a 30 gallon breeder (30Lx18wx12h) and was planning on using a Koralia 1. Will this be enough? I Just don't want any dead or weak spots mainly to keep algea in check but for other obvious reason too. But on the other hand I don't want to blow everything around or have a sand storm!! Thanks!!

Not even close. I'd wouldn't go any less than a pair of 2's or if 3 if you want to do a single pump. I use a Koralia 1 in my 14g biocube along with the stock pump and its sized just right for that.
