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

Hi Chet, welcome to reefs.org.

Well, I would suggest not worrying about it. Unless you experience pH or buffering problems (with your water) there's no reason to dose Kalkwasser as it's usually a means to introduce calcium that is available for invertebrates to use in their growth. You can dose just that to keep coralline growth good, it doesn't hurt anything.

The other stuff is necessary if you have specific inverts (the iodine for arthropods and such--though I was under the impression that they have to consume it, not pickle in it) and the Phytoplankton, being as how you probably have very few filter feeders, would only add to the burden of nutrient export.

So, you by no means have to use any of those, but of the three you might want to dose a bit of the Kalk.

Welcome, Chet!

I have to agree with Seamaiden. The items you have in your possesion are not needed in a fish-only system. Just use a good salt mix.

If you decide to go to a reef tank at some point, in general, additives will still not be needed. Some sort of balanced additive to maintain Alk and Ca, should do it. You will have decide for yourself if Iodine or Iron are needed. I don't dose anything, top off with RO/DI water and run a Ca Reactor, and of course feed! :lol:
