I have a 37g (tall), two MaxiJet 900s, as well a PowerSweep 212 towards the top to provide some surface agitation. I've tried different configurations, don't honestly know what the "best" is, beyond just trying to make sure you have good flow everywhere and no "dead spots". Currently one of my 900s is pointed towards the front/left of the tank (can't point to center as that would hit my lr
direclty), so the flow ricochets off of the front glass back onto the lr
. Other 900 is shooting straight across the tank in the rear. The PowerSweep 212 is towards the top of the tank.
When/if you turkey blast off your lr
occasionally to get debris off you can watch the debris to see how your water flow is working (or is not), but I don't know always how to tell how flow is between some of the lr
I don't use a wave master as some suggest yet but may switch, if so I'll probably change my ph
configuration --yet again!
