Can someone help me understand what sized air pump i need?
My set up is going to be 6-8 nano tanks, each is almost exact 10 litres on 2 racks (4 on top and 2-4 below). Im using ATI Hydro sponge filters in the mini size for all the tanks and want all of them to run off the 1 air pump with a gang valve to split everything. At the moment im using my TetraTec ASP100 but even though it seems to work, water flow isnt great- this model does say its for 50-100L but i dont know what its LPM rating is.
How many litres per minute does a pump need to be rated at for this sized nano tank to give sufficient filtration?
