ASM G5 for 500G total volume

[br1200]

Guys,

I just got a 420G tank & 100G sump. Would a ASM G5 (rated for 700G) be enough?

Thanks

OK, let me ask it another way:

What would be a safe margin for a SPS medium loaded reef tank skimmer size?

Is it double the water volume, 30%,50% ?

Thanks

I don't think so. I had a ASM G4 skimmer for my 120g SPS heavy loaded reef tank. It worked very well but I would not have used it on a larger tank. I would definetly go with a bigger skimmer if I was you.
