Getting an Aqueon Evolve 4, looking for tips...

Yeah, the flow on the Evolves is quite strong. I folded up a piece of panty hose a couple of times and rubber banded it over the output. That seemed to stem it down to an acceptable rate.

What would be considered an acceptable rate? I dont want to stress the pump. The flow as it is you can barely see the water line move. When a piece of debris gets infront of the power head it blows it around pretty good.

And I put my Betta in today, and he doesn't seem to like the flow much. I am going to try to reduce the intake as well, by placing a sponge in between the slots and the filter. See if that helps.

I have read that you want to aim for only 4-5 GPH movement.

I did not want to reduce the flow through the output anymore than the quarter on the added valve, for fear of straining the pump. I read from someone who supposedly helped design these Evolve tanks that the pumps for the Evolve 4 and 8 are rated at 100 GPH.

So I purchased a 2 pack Fluval Foam thing. It fit in perfectly over the intake slots.

Are there any thoughts about this method? Did I buy the wrong item? The flow seems to have reduces a little, trying to gauge by how he is reacting.

I have the evolve 8, so a little different, but:

i turned my pump output all the way to the bottom. i did some diy flow measuring with a measuring cup and figure that it is still supplying in the area of 55-60gph which is still a fairly brisk output and kinda/sorta conforms to the 10 changeovers an hour rule. the pump pulls through a generic mechanical filter, then a purigen pad, then 750g of bio blocks. I moved the pump (after extending the hose) under the first stage of the sump housing and built a little shelf for the bio blocks so you can pull them out more easily and to make sure that it pulls water through them and them only. I also found that if you aim the output nozzle straight up it agitates the surface pretty good but only really has current in the front right corner of the tank.. there is a nice dead spot in the middle and the back left corner for my fish to hang out if he so desires.
