Cor 20 enough flow for??

[Ribo15]

I have an 8’ 240 gallon tank and I’m curious if anyone has thoughts on whether a cor 20 would suffice for my tank turn over? I like the apex line but I’m not sure the pump is rated for enough flow? Total running system volume is probably 260 gallons once rock is taken into account and sump volume.

I have a COR 20 on my 120 at 40 percent and it has plenty more flow to go. You would have to run it pretty hard to support a 240 gal tank. I am currently upgrading to a 225 gal tank and plan on using 2 Cor 20's.
