hydor ario 4's noisey and cause vibration.

[mos90]

i added 3 of these to my 300g. i placed them under the water mounted to the top braces across the tank. they are nice but they are so noisey and cause horrible vibration. it cant be good for the fish.

i think im going to have to get rid of them and go with an external air pump and led night lighting separately.

the only good thing about them is they combine air and lighting together.
id would install them on the bottom but the sand clogs the motors and they wont spin.

anyone else have the same problem?

Those pieces of junk went in my tank for about five minutes. I then promptly removed them and sent them back for a refund. Actually, to be honest, I tried like crazy to get them to be quiet to no avail....then i got rid of them!!!! Silent and vibration free my ***!!!!!!!!!!1
