No it isnt. Above 60gph, the mag 3 owns the mcp. Look at the P/Q graphs of the pumps side by side. The mag 3 should push more fluid through the loop and much faster. For a bong setup, it is important to have a lot of flow through the shower head thing.
There is a guy on the OC forums that has a mcp 600 shooting a stream of water about 4 inches in the air, but when I put my mag 3 in a sink and turn it on it shoots water in my face, and I'm 6'2" (true story
).
