i have had a CA and Kalk reactor for a while and have had a little difficulty trying to control my levels with these two reactors so i was woundering of switching to b-lonic and dosing of a litermeter. how many of you use either or. and how does it work for you. Also which pair do you recommed for 180 gal reef sps tank. I was told the bionic is much easier as long as you dose the proper amount.
