who here keeps macros in your display? i had about a dozen different varieties before my recent lighting upgrade. i have since removed several of the more aggresive ones to keep maintainance down a little. i have had pretty good success with this, nitrates always undetectable, most corals showing steady growth(exept a few polyps over run by some of the aforementioned aggresive macros), and i would consider the fish load a little high. i have had macro in the tank almost since it was set up, never saw much undesirable algae, once let a patch of bryopsis get pretty big(about 2-3" across) because my GF thought it looked pretty, but when i saw it start popping up elswere, i pulled the rock, srubbed it with a toothbrush, and put it back. i had to repeat this a couple times, but i think over a couple months it basically got out competed. i am also using crushed coral for substrate(about 3/4") on the idea that it provides more spaces for mirofauna, it's full of pods, worms, and starfish. kind of a "refugium in the tank" idea. i have two spaces behind the rockscape where i keep a big wad of chaeto on one side, and a big patch of ogo on the other. they are both full of baby snails. i just thought i'd mention all this because i relize it's pretty unconventional, and it appears to be working out pretty well. thought i'd fish for some feedback on these ideas.
