I also have a couple custom in-line pH probe holders for $10
(or will include with the purchase of one of the reactors or controller)

I would like the in line pH probe holder. Can you send me a picture and phone contact to wasp@comcast.net

Thanks.

Probe holders all sold.

Prices dropped on all other items!

Reactors, pH controller, CO2 tank and regulator still available.
