they are not to make waves. my opinion is, they are good. good for turning a mj1200(295gph) into a 2100 gph powerhouse(or 1600, depending on which propeller)
That much flow? Almost twice as much as a Koralia 4 (1200 gph)? That would blow the side glass off my tank
For less than $13.00? Doesn't sound right. I just received an email from another fish supply place and this is what they said about the sure flow:
