Okay I just ordered my Maze3, geforce WB, BI Xtreme, and all I need is a pump. Looking at Eheims website it says the input and output of the 1048 is 13mm or 1/2 inch. Danger Den is telling me it's 3/8 inch. I have a 1046 which has 1/2inout, and some silicone tubing and I can see why they would recomend 3/8 tubing. I really want to maximize flow and want to stay away from 3/8 tubing what would you guys recomend?
I was also wondering where a coiuld get replacement fittings for my ehiem as the output fitting broke. What size thread is that?
