Got this to put some fry in. Wanted an external setup as my tank is to small. Sadly doesn't fit over my tank edge. (Aquaone lifestyle 76). Will fit over 20mm edge or smaller. Not my 32mm edge. Nice and solid though. Definitely wants either a second air pump and/or a really big main pump for the water flow. Tried taping into my pump but it was to small to run the waterflow and bubbles in the main tank at the same time...Good setup though, just the edging got me..
