calcium reactor regulators


New member
What are some of the better regulators to go with these days?
and do they come with solenoids?

I dont know that much about the calcium reactors other than the Geo models are very good.

Does anyone use other brands with ease and great success, such as Korallin, PM, Octopus etc

Do you nee a PH probe & monitor to use with sucess or can i go without until i purchase a controller?

any help would be appreciated
