I disagree. I've got an SPS dominant 29g Biocube, I'm burning through 80-120ml Alk per day, that's while dosing Kalk @ 2TSP per gallon in my ATO. wasn't doing anything. I was losing 1 dKH in like two hours during the day . I'd dose all day keeping Alk up to 9, and I'd wake up to find my dKH at 6, once at 5.8-ish. Right now I'm adding Vinegar to my ATO / Kalk to dissolve more than 2 TSP per gallon.
If you run a successful tank, it will become demanding. And you will need all the same gear a big tank needs.
My first suggestion to OP is to get an Auto Top Off -- And Kalkwasser. Start with .5-1 TSP Kalk per gallon in your ATO reservoir. You can add upwards of 2 TSP Kalk per gallon of water. Once that starts falling behind (when your tank is growing and gaining maturity) you can make your Kalkwasser solution more saturated, up to 3 TSP per gallon, with the addition of 45ml of vinegar.
The smaller your tank, and the more successful your tank is, the higher quality gear you'll need. If my tank were 60 gallons with the amount of livestock it has, I would have no problem dosing by hand. But as it is, I need to dose like 10-12x a day, because too large of a dose would basically be an Alk spike. 18ml Alkalinity raises my dKH by 1. I have to dose 80ml+ per day, and I can't dose more than 18ml per hour and a half, or it could harm my tank.
