Thanks! I am not carbon dosing but given I have no fish in here I am not adding any nutrients to the tank so in the end it is a ULN system. That is why I dose Aquavitro Fuel, essentials coral food in the form of amino acids, fatty acids, vitamins and carbohydrates.
I know he volume is very small and this creates a challenge in terms of keeping stable parameters. I hope to keep them in check with the auto doser but we will see. given the low amount it is required (2ml per day) I would need a high be doser to be able to spread across the day in very small quantities like 0,1ml 20 times a day. My current doser is probably not accurate enough to divide 2ml in several small doses so inevitably there will be a little seesaw effect as the tank consumes Alk between dosing, but I hope this will not be too severe.
Thank you for the feedback.
