I was using a burnt out bulb (my own fault). Since I didn't have a PAR meter, I had no idea. My PAR at the surface of the water was around 75.
I killed off a LOT of SPS, and severely damaged a good amount of others. I honestly cannot believe the Green Milli survived. I basically took a 6 month step backwards SPS wise.
I haven't considered ZEO. Honestly I'm taking a in-depth look at the various ways of feeding a reef, and the foods we offer to our corals. I spent an hour or so on the phone with another guy about this very topic the other night. There's just so much information to digest... so I'm taking it one chunk at a time right now.
I'm particularly interested in the use of ammino acids and carbon dosing... but found it's particularly difficult to find good information on a lot of the stuff out there beyond... "This is what I do."
Regardless, I am waiting until the SPS rebounds back to my starting point before I begin anything. That way I should be able to attribute results to a specific action... because right now, anything I do would more than likely show an improvement, as my corals were so neglected for 2 months.
