Forum » Ario 4 Depth restriction?

I have purchased an Ario 4 for a new tank I am setting up. Unfortunately, I didn't realise there was a restriction on the depth of water in to which it can go and my new tank is quite tall!! Can you explain why there is a restriction? And what would be the problems if I was just to run it at about 60cm depth? Thank you, Gary.

Hello, the Ario should work, but it might not deliver the same amount of air as it would if positioned at the correct depth (the venturi principal that creates the depression that sucks in the air is influenced when depth is increased)
