Well, I installed my new 6000's yesterday.
First impressions are disappointing.
I installed them in the back corners pointing towards the front middle to front opposite corner.
I had a bunch of detritus laying on the bottom in the front corners and they were barely disturbed.
I don't have a lot of rock in the tank, and the streams are positioned above the rock layer so there is a clear line from the stream to the front of the tank.
I sucked all the detritus out and will keep an eye on it to see how it works starting with a clean tank.
I also bought a multi-controller but haven't figured out the instructions yet.
Are there any better explanations for what all the different settings do?
The translation is a little weak, and there just isn't enough explanation.
I'm hoping that maybe with the correct setting it will help keep detritus from settling on the bottom.
