I bet Carol Gulley already knew that, but was just holding back to see
who esle may come forward and offer that bit of advice. I bet that
Carol Gulley aka Koi-Lo taught that to Altum as well.

Hi , Thank you all for your replys , the filter is a internal filter which
produces the air wave across the surface for the oxygen , my ideal soultion
would be a virtually silent internal filter which did the same job , can
anyone post some a link to reccomended as used by the poster internal

internal , i'm happy to pay the price for the right filter , but would hate
to spend the cash and find i was back where i started , but with a spare
filter , i may never use , thank you all.

If you're talking about the venturi on your internal filter, just stop
using it. (A venturi device sticks above the water line and pulls
bubbles into the filter outflow.) Venturis are noisy and usually
completely unnecessary. Set the filter outflow near the top of the tank
so there's some surface movement instead and don't stock too heavily.
