Oil in Calcium Reactor's Bubble Counter

[bayondai]

What kind of oil can I buy locally for my calcium reactor's bubble counter. I know marine depot has something called bubble counter liquid, but I would rather just pick it up locally.
Thanks,
Mike

I just filled mine with RO water.

Mineral Oil - don't use RO water as that can calcify on the needle allowing the Co2 through. Eventually, you may need to loosen the calcification or even buy a new regulator.

Can you explain this a little more? Maybe we have 2 different reactors here but the needle valve that controls my CO2 bubble rate would never get wet as long as there was gas in the line but there is also a check valve for added security. In the bubble counter it's all 1/4" airline tubing and in the event it calcified it would stop to flow of CO2 not increase it. I also just re-read both manuals (MRC and PM) and both say use RO or fresh water to fill the bubble counter.

What do I get the mineral oil, a supermarket or pharmacy?
Thanks Again,

You can use glycerin, you will find it readily available in any pharmacy or supermarket, Its inert and widely used. small bottle will cost about $2.

I just picked up the mineral oil at the supermarket for a few dollars. I am going to try it out tomorrow.
