Look in the Tunze USA forum on this site. First page under supporing vendors. I ordered 2 6000 streams for my 120. I don't want a stong current. My tank is to be delivered Saturday and the Tunzes won't be in for a few weeks. Therefore, I can't offer any useful advice on how they work. I found a tremendous amount of advice in this forum. Also, I think someone from Tunze frequents that site and will give you good advice.
thankx for an answear...tank would be 48x24x30...oceanic reef ready..i will have 2 iwaki for retutrn and i would like to get strerams for curent,so if u think 2 6000 would be the best ..i probably got with it...
