I just wanted to know if anyone out there is having the same problem I am having. I have a diy co2 diffuser made out of a gravel cleaner with a power head attached to the top of it and some filters shoved in the bottom to stop the co2 from just blowing right out of the bottom. the problem is that whatever I put on the end of the gravel cleaner to stop the co2 from immediatley escaping gets blown off by the power head after about a week. I have used canister filters packed very tightly in the bottom with nylon over the end of the tube with 3 rubberbands holding it in place and still blows off after aweek, from build up (very very very little build up) If I use a smaller power head it does not have enough power to keep up with mixing the co2 in the tube. Just wondering if anyone out there has come up with something different for holding the co2 in the tube to be mixed thouroughly by the power head, it would be great to know. As for anyone else that reads this thread any brainstorming would be appreciated for I have been thinking about this one for a couple of weeks. almost forgot to mention that just plain old nylon over the bottom stops the bubbles from escaping with no other filters, but it flies off after a week even with 3 rubberbands on it. Thankyou all in advance

If you use a piece of course filter sponge (like for an Aquaclear) you could drill a small hole on opposite sides of the tube and stick a piece of skewer/toothpick through the holes, piercing the sponge. That should hold it in place.
