CO2 outgassing in cannister filters
Karen and APD:
I was browsing through the archives where you said that a cannister
filter would outgass more than, say, a biowheel setup. I have an Eheim
setup with the spraybar underwater, aimed away from the surface of the
water, which I thought would cause little to no outgassing compared to
another setup. Can water movement underneath the surface of the water
(which is without ripples) cause significant outgassing?
Thanks.
Hari.
