Depends on what else I run Brad. I am trying to run sumpless and powerheadless,{nice word}. It does need help. Not enough alone. I shut everything down and their was still an excellent current. Lots of rebound and movement all the way across my gravel bed but I dont think it would be enough.
Mind you, I am still playing with it. Took me half the afternoon, looking goofy at the bracket, trying to figure it out. Needed one of them engineers types.
If I ran my sump, it would be enough with my 3MD return and the scrubber dump, {which is not much}.
I would like to put another on the other end. I have to figure out my sump situation first. Because of the scrubber dump, I am going to have problems with my Tunze Osmolater top-off, just running from the overflows. Dont think it will work as the water fluctuates to much in such a small area.
