The only problem is that the Koralia's can't run on wave timers. The koralias need a variable speed controller and not an on/off controller. I have used the Koralia's and it's true that the flow pattern is much better then a MJ or the like. The only controller I know of that will work with the Koralia is a Seio timer because the powerheads are never really off, the power is just lowered and raised. The only downpoint of the controller is there is no alternating action.

Sorry I beg to differ here---maybe I have been confusing on what I am using to run the two pumps-LOL--as if this has ever happened before
I am running a variable timer power bar--it has three outlets to vary the timing of three pumps and three outlets to have current on all the time. I two hydors are off on every 30 sec.
When I bought them I asked if they could be used for this and I was assured they could.
I know what you are saying though--I tried to use two ossicating ph's before and couldn't--they kept grinding.
