Jebao pump decision

[Skimmin]

I would say it depends on the thickness of your tank. I think the rw 15s would be enough flow but whether they'll hold on your glass or not will be the big thing. I tried them on my 300 gal but they would just barely hold on the glass. My tank is a custom 300gal with 15mm sides. If your tank is made with thinner glass or factory made you may be ok. In the instructions it even says they are best to be used with less than 15mm glass. I would say 12mm would most likely be the max. Im hoping the rw20s are going to have stronger magnets then the 15's or I'll be sticking with the two gyres I have.
