Aquarium Advice Regular
I just put in a 5 gallon fuge over my tank. The fuge has a mj1200 pumping water into it thru a 1/2 bulkhead 2 feet up. The drain is a 3/4" stand pipe gravity fed back to the tank. The drain is putting a LARGE amount of bubbles into the tank. Could this be because the the powerhead is pumping in too much water into the small tank. the water coming back into the main tank seems like it is moving too fast thru the fuge. Any suggestions or ideas to stop the bubbles. i have to buy a new powerhead anyway should i slow down the flow or do i have to change the plumbing
