Kalk Drip?

[reeferious]

supplies needed couple of 16 liters ro/di plastic containers that you can buy from safeway, superstore etc, few feet of 1/4 inch flexible airhose tubing, 3/8 inch rigid tubing, 2 or 3 3way plastic airflow valves,plastic funnel. drill 1 each of 3/8 and 1/4 holes in bottle caps and pass respective tubings through holes. attach valve to 1/4 tubing and adjust length so that tube end sits just above kalk residue. silicone tubings in place after final adjustment made. to start drip process blow into 3/8 tubing until kalk begin dripping and adjust drip rate with valve. the setup is so simple and efficient that i see no reason for any method updates. i use 5 tsp kalk per bottle which i made in batches and every so often i soak valves in vinegar to clearup airvalves.
