Hi, I just got my 20 gallon freshwater aquarium yesterday and set it up today with the filter,water, pump,etc... I bought an AquaCulture 20-60 gallon double outlet air pump and didnt realize it had two valves. I only need to use one though ...what should I do??p.s. The bubbler thing that lets the bubbles out is a rectangle and its long but it isnt working in the middle of it...? would that be because of the double valve?p.p.s. the pump came with two check valves.Thanks, Sarah
If the pump doesn't come with any method to shut off one of the outlets, you can combine both outlets into one by using some tubing and a T-valve. You can also use an air valve and some tubing on the unneeded outlet to dead-end it, though that method may be a bit more stressful on the pump.
You only need to use the one valve, each valve will do 10-30 gallons so you'll be fine. As to the bubbler problem (sounds like a bubble brick to me, so that's what I'll call it), it's most likely uneven. If the brick isn't level it won't let out as much air in the right places. If leveling it doesn't work try adjust how much air goes into it, but the double valve won't be the problem for this. It came with two check valves for the two outlets, you only need to use one.
