nope I actually was thinking of adding another #3 back in them days. I had live sand for my substrate. it would blow it around it took about 2days to get the hydors positioned right so they wouldnt disturb the sand much

The Koralias are the best bang for your buck in my opinion...I have a #2 and a #1 in my 20gH...they move a lot of water, but are designed to do it in a gentler way, they are easily adjusted and do a great job overall. When I thought there was too much flow I set them up a little higher in my tank, to a slight angle and pointed them towards one another to create more randomness in the flow.

I have two #4 in a 125g. #1. Is that enough? Do I need more movement? #2. How do you hide them? I haven't learned to do that. Mine are located upper middle on each end.
