Thanks for answering, Byron.
Right now I have a plant in the corner and I can't find any good spot to put the filter really. If I move the tip where the water comes facing the aquarium wall, it still produces some current onto the plants. I think I tried this, and I don't think it helped... I just can't remember why. I'll go ahead and try it tomorrow since the lights are out now.
I'm pretty sure it will still cause the little surface disturbance you can see in the video. I'm still a bit confused over whether this is bad or if it's fine. I don't see bubbles coming down like I did when I had a HOB filter but I'm guessing this still causes a gas exchange?
I'm also a bit confused on the water flow thing.
The filter should produce a water flow sufficient to ensure the water circulates through the tank and filter. This is important for bringing nutrients to the leaves and roots, and keeping the leaves free of sediments.
For this reason, filter flow should be minimal and surface disturbance as little as possible. The plants will then be able to fully assimilate the nutrients.
I'm a bit confused because these seem kind of contradictory to me. :/ One says that you need some water flow to bring the nutrients to the leaves, and the other says water flow should be minimal so the plants can fully use the nutrients and not bring them away from the plants... in my understanding, anyways.
So basically I don't really understand how much flow is too much, and how much flow is too little. :/
Is there any way I can determine which it is? For example, is it bad if it blows against the leafs a little? Or should I avoid any current on the leafs?
