Get the 2 part kit from Bulk Reef Supply. Also get the Ferric Oxide pellets, and some Carbon. Buy a Two Little Fishies Phosban reactor for the FO, and put a small maxijet on it.

That's all I use, and I have a nice healthy tank. Otherwise go ZEOVIT, lol. There's also the NP biopellets as well, which is newer technology, but is getting rave reviews. and make sure you have a GOOD SKIMMER!

There you go, 1k in the hole.

It's all worth it!
