You're also right :-), at least it's the cheaper product, I guess.
I gave it a try, because with my tank I have a big volume to dose.
The Grotech is limited to a maxium volume of 1.9 liters a day and with
my dosage of about 4.2 liters of the maximum concentrated NaHCO3 solution a day, that took 3 channels on the Grotech :-(.
I replaced the AM one with some industrial grade pumps from Harton, a German manufacturer. (one of them costs as much, as the quaddro (4 pumps) from AM :-().
The Grotech is still in use for I,Sr,elements
