This overflow box is the best that I could find,does as It says easily keeps up with my 400lt tank & the quality is outstanding. don't want to drill holes in your tank use one of these overflow boxes, you will not regret It.

Toller �berlauf für wenig Geld!!!

Firstly, I'm very sorry for my poor english.

This aquarium overflow box works fine in my 225 liters tank. However, every 10 days it generates a little air bag that I must to remove using the suction tubing for remove the air. But it works silently and I've never had any problem with it since 5 months ago.

I recomend it!!!

A great product that works as good or even better than most other more expensive brands. Craftmanship is excellent too with sturdy quality arcylic finish. Extremely silent too without gurgling sound of water rushing down to the sump tank. A must buy product!
