ultra lith--and mixed reef (or not mixed?)

Hi

To answer this correctly you need to understand the war between soft corals and SPS in the wild, never the twain shall meet basically.

The reason being soft corals expell a much more potent toxin in the water than SPS and so will always win the battle. So what you will find is that the softies will dominate and the SPS will stuggle.

I know some tanks have both but I have yet to be over impressed with mixed softie SPS systems as you are going against the laws of nature.
