Helping a friend of mine put together a 72g drilled reef tank. Gonna make the existing pumps into backups and get all new pumps.
Before - main return Pondmaster 700 gph
Thinking of doing a Mag 9.5 this time.
Before - Top Fathom 100A skimmer, Rio 2100/692 gph
Thinking of doing the Mag 7 to the skimmer this time. Probably run a Mag 7 on the 15W Aquatics UV
Increasing the main return a bit is good, I'm thinking. With the head height, the Mag 9.5 is gonna be around 700-800 gph
anyway, right? 10x for a 72g.
