I have had bad luck with chalice's as well. Ive had good success with other sps tho as im a beginner myself (about 8 months now) im a fan of keep it simple, keep in mind i dont think i have any super sensitive sps yet. only thing i do is maintain weekly water changes, change filter floss every other day, dose every morning before i walk out the door for work. Thats it. It took a few days of testing the big 3 before i figured out how much to dose daily to maintain good levels. Speaking of i should probably test them again, its probably been 4 months since ive tested LOL The tank has moderate flow, some areas have more than others. I placed my sps in higher flow areas but not directly blasting them. Keeping it simple and not moving stuff around and basically not worring about them worked out well for me. But doesnt work for everyone from what ive read over the years. Also sps can be slow growers, take a pic of when you first put them in your tank then take another after like a month and youll be able to see the growth easier by comparison.
What i have so far
-forest fire digi
-red digi
-blue stylo
-cornbred incredible hulk digi
-sunset milli
-horn coral
-corps purple bonsai
-cobb purple bonsai? (Whatever their names, i have both versions)
-sarmentosa
-green slimer
-Psammacora (not sure if that is spelled right)
-birdsnest (thin kind)
I started off with the red digi. Super easy to care for, and pretty hardy. Its been stung multiple times by my torch and always bounced back. The green slimer is also a pretty easy one, mine likes good flow, has better polyp extension with more flow anyways
