Lots Of Surface Agitation

[Joshy]

Hi there, I have a heavily planted 35L tank that is now cycled and being stocked. I have two individual filters in there that each turn the water over at 200L-per-hour. And with a betta in there the current out of both filters is too strong for him, so I have had to use the spray bars points up-hitting the surface, just to make it ‘okay’ for him. There is a lot (a lot a lot) of surface agitation because of this.

Will it cause me any problems with algae soon?

The tank only has a 8W light which is on for 7 hours a day. The plants are all hardy low light level ones. It does not receive much direct sun light at all. And I do very regular water changes.

Please advice me, im worried!!
Thanks.

It wont CAUSE algae, but it will drive off CO2, which could cause unstable CO2 levels which can contribute to the growth of algae.

Are you able to fit spray bars to your filters? If so try these, but drill out the holes or drill more holes to reduce the pressure, and aim them towards the front and down, mounted below the water surface.

If not, I have seen people make a sort of surface baffle for their fish out of a mesh type tank divider.

Problem is Ad, i already put the spray bars on and deliberately pointed them to the surface. For the sake of the betta. I did previously have the current hitting the front of the tank and then down like stated, but the current was too much for the betta. But i may to drill more holes in ease the pressure and force from each hole more and not break the surface so much.
