jobao rw

[BuschWacker]

I've got an rw4 in my 46 bowfront and its definitly not strong enough. I would think an rw8 would be the minimum.

I have 2 RW8 in my 4 foot 120 and they are plenty good. I think two RW4 would be more than enough for a 3 footer.

I have two RW8s in my 150 gallon tank that is 6 feet long. I have them on one of the pulsing wave modes (forget what it's called). I have them dialed up to max and the wave they make is just perfect as the crest comes up to about 1/4 from my eurobrace. I thought about the RW15s but I would have to dial those down a tonne, so the 8s are perfectly fine for me.
