Air Stones

2002-11-20 by James Owens

Hi List,

I started my foray into making my own circuit boards by ordering ferric chloride and tinning compound from those nice people at Mega. While I was waiting the contruction of the tank took place from glass and silicon sealer. Happy with the tank I installed some fish-tank blue air stones, filled it with ferric chloride, attached the pump and installed a heater. The ferric chloride promptly disolved the air stones. Any thoughts on what I should have used?

Regards,

Terry

I went along to my local pet shop (in Stroud, UK) and bought a bubbler
which looks as though it is made of sintered silicon carbide. It is
about 4" long by 3/4" wide x 3/4" high and has a glass tube cemented
into one end. It is black in color. So far it has lasted well.

You can use a piece of plastic transparent tube, similar to those used for
perfusions or for aquariums.
Introduce it in the FeCl cuve and pierce (using a hot needle)the part lying
on the bottom to permit air to escape. No need for special bubbler.
