I add 1lb ESV (maybe ESB) kalk to my reactor bimonthly. I set the circulation pump to come on for 1/2 hour every 3 hours. I have a 5 gallon bucket of ro/di water that i use to gravity feed the reactor. i drip at probably 10-15 drops per minute. I clean the reactor and circulation pump every time I add new kalk (every other month).


Cheers,

Kurt
