Didn't try to save any of the sponge mass so we'll see if I notice any parameter shifts now.That would seem to indicate a healthy tank environment. Everything looks real good!
Things have been on auto-pilot for quite a while so, this year, I'll start dealing with Ca/Mg for the first time (((always low the few times I've tested))) and finally start adding some more corals since what I have is pretty "sparse" so far.
