Ok so basically have a tube go into the catch bottle all the way to the bottom and then have another tube going into the tank, I noticed you said you put zeolite in your tank, mine's in my room also should I need to worry about this? Would a 20oz. bottle be ok for a catch bottle or a 2 litre be better or a 1quart gatorade bottle, because that's all I have right now, guess I could go and get a 1litre bottle if it's absolutely necessary.
