Stylo Health Opinions

[walloutlet]

So relatively new to keeping SPS and branching out (get it... branching out - coral puns are the best) into some new territory.

Without getting to deep into the numbers, let’s just say everything has balanced out and stabilized in the tank (parameter wise) and looks healthy.

Tank size - 65ga
Salinity - 1.026
Temp - 79F +/- 0.5 in fluctuations
pH - 8.1 +/- 0.05 change throughout 24hrs
Alk - 7.5ish (Trident)
Cal - 440ish (Trident)
Mag - 1350ish
NO3 - ~10 (Nyos test kit)
PO4 - 0.02 (Hanna Phosphorus)
Lights - 2 x Kessil 360’s; 10hr light schedule with 4 hour peak period @ 72%
Flow - lots; 2 x MP40s + Reefwave25 all running pretty hard. If you need a turnover number, it’s somewhere in the 80x zone based on GPH.

So I got deep into the numbers! Lol

Have had this Stylo for a couple months and it continues to grow with nice bushy polyps that looked wicked cool moving in the current. However, noticing a small section on top where the polyps are turning green. From the more experienced and experts, is this a case of the coral expanding its skeleton upwards here or a sign of something starting to take a negative direction?

Appreciate insight, opinions and discussions.

Hard to say. What are the nearby corals, if any? Could have been stung by something. Keep in mind that many corals have long mesenterial filaments that stretch a mile. So it doesn’t have to be a next door neighbour.

Nothing really near by, closest thing is a RBT anemone but he’s a good 4 or 5 inches away. (Right now at least)

Good thought on something potentially stinging it, something to keep an eye out for.
