I am sure that you know that I don't subscribe to the "alk swing killing tanks" thing (or any one parameter for the most part) and that all of those threads are usually overblown, but you will probably find the long term keeping of A. Speciosa to be different than A. Tenuis. Usually, everything is Ok until there is just one event that is the final straw and then people are scratching their heads with both a). everything was fine yesterday and b). my other acros are fine. You can tell me to F Off and I will never post about it again, but just trying to help since you really appear to like those corals. Don't make the mistake of thinking that all acropora have the same care levels. There have been some REALLY solid acropora farmers and keepers who have lost A. Speciosa, and other smoothies, to minor events when most every other acropora was OK. Of course, there appears to be both easier and harder specific A. Speciosa, just like any other kind. If you don't have to tighten it up, then that is great, but be prepared since many others have had to...
