Was originally running 2 smaller pumps to try and move the K1 but wasn't really working. Ordered a big pond pump and stone from Jehmco. This seems to be the golden ticket! Highly recommend this company if anyone is in the market for a pump
Wow! I too have been experiencing some difficulties getting K1 to "flow" the way I would like, using both air and circulating pumps to get the stuff moving. And I need it to move just right, because my granddaughters love watching it...probably as much as the fish, or even more!...so it's gotta be perfect.
But you're using an air pump that looks similar to the one I have that runs all my tanks! An airstone that looks like a chew toy for a large dog! An airline like a garden hose!
