I think it pretty much SPS keeping. Let me know your thoughts.
The list of “easy acropora” is filled with corals that are not acropora, except for yongei. The intermediate acropora includes abros, which is a very difficult acropora to keep ime
But on topic, I have loved robertos tanks and threads ever since I can remember. I have never seen anyone keep such a clean tank so well. It’s certainly a statement of his patience and knowledge of hard corals needs. I have never seen him have coral issues or death problems. Just growth until he decides to try something new. Every tank of his was very different but each was done using his same methods. This is kind of a rare thing, most reefers like to try new things on each tank.
I dont think he is trying to keep any secrets from anyone or doing much of anything “behind the scenes”. People ran away from keeping corals like he does years ago which is a shame. I really don’t enjoy the dark colors people keep these days as much. He has given everyone the info on how he starts his tanks and I just think it takes patience time which a lot of people don’t have when starting a tank, experienced or not.
Either way I am ready for an update on his tank and am ready to get back to keeping some acropora myself again soon.
