Hey Ping, thanks. I was out for a couple of days. That is impressive for 400g!

I've lost sps before after stirring a sand bed, but it was much more than you're doing for percentage.

As far as a Xenia fuge Troy, why can't you have calurpa and xenia in the same fuge? I had this in one system kind of by mistake but it worked well was was easy to harvest both the algae and xenia.

When I've kept sps by low feeding and lower skimming to keep nutrients low the bed hasn't had many issues. But when using a bed, and heavy feeding with heavy skimming I've had a lot of build up in the bed. My best growth came with a BB tank, heavy complex feeding and heavy nutrient removal. It also had the best coloring. But it's hard to pin down what's "best" as it was also the most complicated system!

My current little 50g only has 2 small fish and a BIG clam with a few sps. I feed it very lightly and it's easy to take care of.....but, my growth is slow. I'm also not dosing much that is a factor on the growth. It has a shallow sand bed in the tank and a DSB if the ref. Zoas, palys, and Acans have died off in this setup with low feeding but the sps are very healthy and well colored considering the lighting.
