Wondering how many people are using this toy for their tank?
----------------
it's my opinion that the pH controller isn't absolutely necessary
in nature there are quite big fluctuations in pH, but the fish take it as it
if you're really worried about your fish, and want to maintain an absolutely micromanaged environment, by all means, try it
i don't have one, as seeing how i have no need for it
