I have a 220 total water system, so I should be able to do 20-40 mbc daily--I do about 60-80 once a week. Sometimes twice. I also use mb7 with the calcium carbonate, so will do that once a week. Even twice shouldn't hurt. I usually do after I clean glass and blast/rake sandbedI just do 20ml mb7c on dosing pump every night, and 20ml mB7 with calcium carbonate once a week. Tank 75G with 30G sump. I just picked 20ml as a starting point and just kept with it, been doing it for a few months now. It has kept my ugly stages at bay for awhile now, have a slight cyano outbreak right now but is manageable.
how do you keep the stuff shaken so it doesn't settle
