well i have a 150 SPS dominate reef and i still only drip Kalk from my stirrer and do 5 gal per week. my levels are still excellent until the day comes to get a doser i have had many ALK reactors in my time i hate them you never get the proper dosing and too many drips here to many ML there not enough bubbles here.

I like the Kalk way for now ,
