Co2 Ph Monitor/control

[Zikofski]

are these any good and worth buying ph n co2 control? I've never knew the existed until i saw a youtube video for them?

do anyone on here use them and are they worth the money to buy? i was looking for a digital ph
meter when i came across these

I don't use one because of the price, but they are reckoned to be the gold standard method of controlling CO2.

I wouldn't - Calibration aside you're asking for fluctuating CO2 [algae] - A timer and solenoid would be a cheaper wiser investment, and I'd guess you have them already.

hmm okay i thought it would keep it more stable m get less algae oh well, i do have solenoid and times so no problems il keep to them
