jobao rw

[garwood]

i am looking for some advice on what i should use for flow, i have a 70 gallon tank basically 3'x2'x18" mix reef. something like would 2 or 3 jebao rw4 be enough or 2 rw8 or a mix. everyone thinks they have a ton of flo but i see such a range of tank sizes using same models. thanx
