Surface is a steady current with just a very light rippling effect (no splashing). I enlarged the holes to slow the current yet keep a higher flow, and it seems to work well without any dead spots. Don't want to go against the glass as while it decreases surface current it increases current along the bottom.
Thinking of tying some of the plants in a loose bunch to the center support bar with fishing line, lol. Possibly might also create a calm area so the hatchets can relax at the surface as well? Wondering if anyone else has dealt with this and what worked for them...
Other than not having the current agitating the surface theres not a lot you can do really, I had this same problem and asked the same questions, and in the end I just put up with my floating Salvinia and water lettuce, and now I have some amazon frogbit also being spun around the surface.
I posed the question about lack of surface agitation causing lack of oxygen in the water, and kind of got the answer that surface agitation is not entirely required in a planted tank. Which I have, and I tried having the filter return pipe pointing down and at the back of the tank, so there was NO water agitation, my floaters looked lovely and tranquil but I had a crisis with nitrite around the same time and freaked out, and turned the return pipe back to the surface, and left it that way since (I am not saying that was the cause, but I wasn't taking any chances). I am no expert, but apparently having water agitation in a planted tank set up is a bad thing, as it drives Co2 out of the system which is needed by the plants... I worry about the fish though.
Using some kind of baffle has also been suggested, something that sits in front of the holes that disrupts the current flow.
