| Re: "Balling Method" for supplementing I am speechless . Congratulation you have resolved to apply the Balling method. You will see very quick, as complicates as it at first sight look it is not. The amounts used by me of the required chemicals is chosen in such a way, with a regular examination one overdose is to be excluded. To your "still" small "problem" because of the GroTec III NG dosing pump. I developed at the moment for my smaller aquariums my "own" “dosing system. As soon as I have this "arrangement" ready and she works reliably, I will publish the result here. I am quite sure for some DIY-Fan it will be interesting and above all substantially more reasonably than one expensive GroTech NG III. |
