I have having a submergable pump, i dont have the money to buy a inline right now. I got a big tupperware container sitting in my case, it barly fits in it also. Anyone got any good ideas on a smaller rez or possibly turning a submerged pump into a inline(dont think possible with many pumps). I was thinking of a rez that fit almost perfectly around the pump with like 1 cm of space surrounding the pump and is inclosed. If anyone has some good idea i could use them, thanks guys.
