Re: [APD] Re: problem with tank/regulator seal

[Dave & Robyn Wilson <aqua_green at bigpond.com>]

I run an aluminium CO2 cylinder to a welding regulator (Australian
regulations / specifications) then to a fine metering valve.  There is a
hard white plastic (teflon maybe) washer between the bottle valve and the
regulator.    Each time I change a 22kg bottle I go over the whole system
with soapy water spray.   Occasionally there is a leak.   It does save you
some money if you find leaks and fix them.   The soapy water spray makes the
small leaks visible.  Try not to spray soapy water into the water of the
aquarium.

Cheers
Dave
