I have a canister and the instructions say that I can have some slack but I should not have any loops or sags.
I don't know why.
I don't have enough space for a heater and in-line CO2
if I run the tubing straight from the canister to the bank.
Do you see a reason why I can't or shouldn't do this? (Have the tube come out from the top of the canister, go down and then back up).
The heater has to be upright (it can't lay on it's side because that would be too easy).
