Product question

[fishman]

What do you guys use as far as additives to a reef tank? I have 90 lbs of LR with 1 anenome and some feather dusters growing off of the LR. I want to put more coral type things in the tank later and also am setting up a reef now. I see a lot of people using calcium and kalkwasser...what else and also what brands? Is Kent good?
Looking at getting some of these type things at a LFS and need to know.
Thanks

Kent is pretty weak.Seachem and ESV are much better. All i use the ESV B-Ionic and water changes.
