I have a 29 gal set up & two jets - finally added my fish 3 angels & a placo - the angels are getting pushed around by the jets.
I had them running this way: the Right one aimed left across the back of tank & the LEFT one aimed to the front (hoping for a circuit). This made it hard for the fish to eat, so I aimed them both downward a bit, but I still see the fish having problems as they swim they suddenly get caught in the jet flow. I also have a regular side mounted filter in the tank.
Any ideas are appreciated - I bought the tank used & do not have the jet systems in my other tanks, so a newb to them. Dunno if the fish will get used to the jets in time?
