what to put in tank

[scottdwh]

I have a 75 gal that has about 80 lbs of lr and I also some mushrooms and an anemone. I am planning on getting some kind of polyp also. I use RO water with IO salt. What other kind of chemicals do I need to add to keep corals growing good?

I also have a few shaving brushes in there. I heard that they can suck the calcium out of the water. What can I add to raise up the calcium. I know kalkwasser would work but I dont have a sump and dont know how else to drip it in the tank.

They have drippers where it's basically a 1 gallon jug that has a spot for a hook you can stick into your wall over the tank. That would work for kalk. Otherwise if you have some silicone around you can probably make your own out of a milk jug.
