[AquaticLife] new tank
Those measurements add up to 19.94 gallons. What do you mean by smaller? Shorter in height? What are the dimensions of your current tank?
I would use it to increase the water volume of your current tank.. either with the bridge or with the U-tubes. Either would increase the water volume. If you want a separate H-tank or Q-tank, which is certainly recommended, get either a 10G tank or just a clear sterilite storage box which you could put away when not needed… or use it to hold all your non-chemical aquarium stuff.
Considering the cost of building a bridge out of the poly tubing, I would save that money towards the much larger tank you will eventually need. Two 20G tanks will be OK for now but if your fish aren’t permanently stunted.. you do have goldfish, right?… they will outgrow the space and water volume provided by the 20G’s. If you are going to do the DIY 4″ or 5″ square bridge out of a sheet of plexiglass, then that would be low enough cost to do for now and you could reuse the bridge on two 55G tanks or something like that.
