My current tank is a 125g mixed SPS dominant...it's been running 3+ years and have had great growth and coloration, my sticks are thriving.....and I don't use a dosing pump....I use a kalk stirrer and manually check levels and add as needed. My issue is not with this tank, I am getting an IM 25g Nuvo Fusion Lagoon tank and want to use a dosing pump. I plan on adding zoas, lps and maybe a monti and a stick or 2. I'm trying to figure out how I can implement the dosing pump, I know I should be doing for calcium, alkalinity and magnesium but there is so much confusing info out there on what to use and how to use it. Any help, tips, info on products I should be using (assuming I'm right on dosing for these 3, if not, please provide your expert advice).....thank you!!!!
