hey there i know i dont jump into the fresh water side often but i need a little advice..
i scored a great deal on a 55 gallon and a 20 long
my intention is to turn the 20 long into the trickle filter for the 55
i am using a sterilight 3 drawer container and the set up is as follows
top will be filter pad
middle cut straws and plastic scrubbers (they work great in these from what i have read and i have used them in submersibles with great success)
the bottom will be for running a bag of carbon when needed
then the water will pass into the 20 long and out to the return pump
my question is should the carbon drawer be submerged or just above water level???
