In my aquarium I have a small problem with dirt accumulation in a few places with a clear cause for me (the flow is broken by the stones in front and therefore does not reach the bottom backside of the tank). I want to see if I can do something about that with your help. For convenience attached two photo's of the scape construction with arrows of the water flow from the spraybar on the back wall (hopefully clear enough).
Now I'm thinking to add a flow pump but I have no experience where, I want to prevent it from working against the current flow and therefore cause more problems.
I think I have sufficient waterflow/current in the aquarium but only suffer from these two dead spots.
Point of attention: What I have learned is that black brush, or BBA algae (if present in the tank) thrives in high current, in my tank you see that the stones in the front have the most BBA + the back wall in the middle above the sand. So exactly in the places where the current hits the strongest and has free play.
More (higher) flow is therefore not necessarily desirable, I think.
Also note: this thread is not ment to solve my BBA problem, I'm working hard on that issue with promising results.
I am curious what (positive/negative) effect adding a flow pump has in the following places:
I am also curious how strong a flow pump in my case should be (l/h), the tank contains about 300l net water.
- Red = the spraybar over the entire back wall.
- Blue = the intake at the bottom left in the back.
- Green = the flow of the water as I imagine it should go, I imagine that this goes in a kind of funnel movement from right to left towards the intake..
- Purple = the places of soil in the back of the aquarium where dirt is accumulating.

I am curious what (positive/negative) effect adding a flow pump has in the following places:
- top left flow to the right under the spray bar
- bottom left just above the intake, flow to the right more over the ground
- at the top right flow forwards with the current flow, but with that just more flow from the right side (in the hope that the dirt will 'fly' with it towards the intake)
- top right flow to the left under the spray bar (now follows the direction of the water)
- bottom right, just above the ground, flow to the left (there are taller plants here, so this may not be possible)
