[quote author=reefman_MC link=board=Newbie;num=1082074566;start=75#89 date=05/22/04 at 20:47:44]I have the 75 gallon All glass aquarium with the middle overflow hook up and I have a Mag 12 return. Which is 1200 GPH and it runs 2 feet to the aquarium. I thought that when you had a drilled tank it could be any GPH. [/quote]
hmm i was reading this from the AGA site
[glow=red,2,300]"Aquariums up to 110 gallons are fitted with one MegaFlow™ Overflow and are rated for a maximum flow through of 600 G.P.H."[/glow]
