Wave maker apistogramma question

[Stephen Zawacki]

Hey guys I have a question for yah I have a fluval flex 32 gallon it has a pair of apistogramma baeschi and 12 cardinal tetras, I wanted to add more flow, was getting plant scum on the top of the water I added this wave maker below. I know they don’t like flow the apistogramma , I turned it alll the way down and pointed it upwards for surface agitation. They seem fine is it ok?

Probably Ok. I'd suggest just adding an ayirstone on a rigid airline down the back instead to break up the surface with mild agitation, and bring in O2 to the tank.

I’ll second that. 
 

The wave maker runs $70.  An air stone should provide plenty of surface agitation for considerably less money.
