Re: silicon sealer and CO2 - bad combination

I use pressurised CO2 with a bell (entering from below)...
A small water pump forces water circulation in the bell (entering from above) !
I get the same yellowish slime that slow down the water flow further and further till I clean my tubing...
It smells like bread to me !!!???
So I thought of yeast (from nowhere cf. the pressurised CO2)...


PS. Are silicone tubing clear for ever (or do they become whitish after some time) ?

| tubing running from a yeast generated CO2 setup or at the point where it
| exits into the tank. I have seen it myself countless times. I have never

| unsighly and kind of disgusting) as I've never heard of it hurting anything.
| I've even observed fish eating it without harmful effects. The best cure for
| it is to just clean out the tubing, sterilize it and then start again with a
| fresh batch of Yeast/Sugar/Water.
