PH Controller

[PohSan]

I am thinking of buying a second hand PH controller.

Has anyone use a PH controller before?and Is it a necessity for planted tank? So far only see dennerle brand. Is this the only PH controller in the market. Finally and most importantly, how much.

Thank

PH controller IMO is a premium product therfore it is good to have but not a necessity.
