Aeropars said:I'm thinking of is a ex1200 but then should I replace the eheim with it or should I run it along side? I dont want the fish to struggle swimming with too powerful a current.
an extra filter will be more beneficial than a power head, due to extra bacteria, but if you feel your current filtration can deal with ammonia etc.. get a power head. more filtration the better
i find all of my fish love the current, finding there way into the mainstream of water.
Th e Phantom tetras are going! i've just installed 20 lamp eyes and my god there a stunning fish such wonderful eyes. they've just given the scape a whole new feel 8)
