I just bought a used tank from a friend. It is a 75 gallon fish-only tank with some live rock, live sand, halimeda plant and 3 damsels. We moved it and change 20 gallons of water. All levels are good and clearity is great. My problem is I have no idea what chemical to add in it, how often and how much. It came with a bottle of Kent liquid calcium, Kent iodine, and DT's live Phytoplankton. They said something about add a cap full a week and said look it up on the internet and you'll figure out the rest. I plan on keeping it a fish only tank for a while.
Thank you for your time,
Chet
