No I don't have a controller. All the info is awesome thanks. I think in going to order the RW-15 just cause I can get them for the same price as the RW-8 and I'll turn them down for now.

So I installed the RW-15 and let them run over night and I checked the tank after work today and I moved a lot of sand around so I turned off one of the pumps for now until I can see if there is a better way to set them up in my cube tank. I was wondering if you guys had an idea on the mode and placement of the RW-15's. I was also thinking that I might have to change my aqua scape to soot these power heads. Some thoughts would be appreciated. I'll post a pic of the aqua scape
