Bubble counter Special Effects
 

Instead of using water for a calcium reactor bubble counter, use glycerin instead. It has the viscosity of motor oil but is crystal clear. the bubbles will rise much smoother and slowly making it easier to adjust the reacotr. Plus it gives a little more back pressure to the needle valve for a more precise dial in.

Glycerin can be found in any pharamcy for a couple of dollars for a small bottle.

Hi Bryan,

Personally,i wouldnt use it.
Escpecially if the bubble counter is not permanently mounted,or the check valves are getting old.

If the counter tips over this would force glycerine into the reactor pump intake.

I believe Sera bubble counters use glycerine but it has a built in check valve.

I wonder what glycerine does to a reef tank? :confused:

Hi,

I really don't know what it will do in a reef in large quantities, but it is available in food safe versions. In small quantities, it can be used as a trace element for hard corals.

I have a check valve. Even if the valve failed the bubble counter only holds a small amount of glycerin and I don't think it would cause any long term effects.
