so I have a small HOB breeder box that I keep some cheato in , the pump I bought is a top fin and its the smallest one lol so it's kinda a small flow rate for a 40 gallon tall , so I found the same pump (small top fin) and I have some extra tube and I know somewhere I have a multi valve switch and some extra tube, could i use 2 air pumps the same size and have it tied into 1 tube to return to the breeder box? Or am I wasting my time lol .
