How big of a powerhead do I need for a 12G Nanocube? I was going to get a Maxi-Jet MP - 400 powerhead and the built in one is that enough flow in my tank?
I have a 400 in my tank and it wasnt enought so i cut the tubing and teed the stock pump and maxi together untill i get my maxi 600s (one for return in first chamber and one for the last chamber) I read that you want about 20x turn over rate
Yes you can upgrade... with a powerhead. I do not have pumps in the show part of my tank .. their in the chambers. Maxi jet powerheads will replace your stock pump. Look for a maxi 600 or 900. Should drop right in with the stock pump tubing ;-)
