Hi Jess, I replied your PM, didn't know you were referring to my old post ;-) Check GeToChKn's thread : http://www.plantedtank.net/forums/sh...+treated+water
The tall vase way, I use about just 2 hand full, or make a softball size ball. The tall vase way is doable if you don't have many tanks. Otherwise, check GeToChKn's method or derive your own modified method.
PS: don't use the first few squeeze. it may be too strong.
