okay so I checked the flow, in the process extended the small crack in my frag tank and it started leaking so I had to replace it with a new one.. yay for 10g tanks only being like 12 bucks... drilled the new one and got it setup.

anyway, to the point, I checked the flow into the tank and Im getting ~112 gph through it... so 10x turnover, total of 50x "flow"
