well, if you want less, fill the tank more. My 30g has that style of filter and about that much motion, and all the fish and plants are doing fine.

I would not term that "little" but rather approaching the excessive. While the plants might manage (the CO2/oxygen exchange will be significant with this much surface disturbance) through this, I would be even more concerned over the fish. I don't know what species are in this tank, but if they are forest fish they should have a means of avoiding that much water movement. It is stressful if they have no escape day and night. On the other hand, some catfish such as certain pleco and spotted woodcats, hillstream loaches, etc. need this sort of flow or they will be stressed out and thus weakened.

This is my only complaint about HOB filters in general. They are absolutely exceptional in a tank with Hillstream Loaches, but are less than satisfactory with quiet water fish.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

I cut down a replacement aquaclear filter sponge (fairly porous), and attached it to the output chute of my HOB filter. The sponge is partially submerged in the tank and really cuts down on surface agitation and water current. I'll see if I can attach pictures when I get home form work.

I would say "brilliant" but i'd monitor ammonia and nitrite levels to be safe, you are technically impeding the flow. Byron has tanks that have no filtration, so he may be a bit biased against surface agitation

The sponge is very coarse, with open cells averaging 1-2 mm in diameter. The water level in the filter does go up a very small amount, so flow is reduced, but not by much. If your filtration/ bioload is marginal, then it may be a concern.

My filter is on the far left side of the tank so the fish do have from the center to the right side where there is no current although they do swim the whole tank.

I have Tetras and 1 SAE and all seem to be doing well.

As for plants, all have new growth and seem to be doing well too.
