Thanks, i already have sps and i was worried that it could prove to be too much of a change for them.I wanted to have a lot of flow so I removed the sand and put zoanthinds and other softies on the botttom glass. They are my sand bed lol.
It is much easier for me personally to control my nutrients this way. Now even controlled dosing NO3/PO4. No worries about dinoflagellates.
Easy. I drained all water to the top of the sand. Scooped out the sand, put back in the rock, coral, etc and added a bunch of SPS. Tiny cycle.
