Regarding the tort vs. echinata, I dont exactly know. I only know this was called a tort when I bought it. That may not mean a lot. I kind of thought gomezis and maybe echinata had a lighter coloration usually. Again, that may not mean a lot.
This coral has been very high up almost directly under Phoenix 14K DE HQI lamps through most of it's growth. There was short time under T5s for a few months up front. And a couple months ago, I switched to Ushio 14K just out of curiosity.
Someone asked about the Ca reactor - I dont have one. I may need to get one eventually, but I am resisting buying any more equipment until I upgrade to a larger tank, which may be in a year or so. In the meantime, I have been experimenting with getting a tank like this to work by other methods - namely using kalk for 1.0 - 1.5G/day of top-off and dosing 2-part Ca and Alk buffers. But quite frankly, I admit I can not keep up with Ca demand anymore. It seems to stay at 340-350 or even a bit less unless I do some major adjustment every couple/few weeks. Recently, I started making my own 2-part solutions and bought a auto doser to start adding it slowly throughout the day. So now I'm not afraid to dump LOTS of this stuff in. I'm going to give this a go, and see how well it works.
