My tank is 4 months in, I got this Sunny D frag with 2-3 poylps a few months ago, there's about 8 poylps now but they were always wide open and happy, unlike my other 3 frags of other zoas.
The only recent change I made was add Kalkwasser to my ATO, hoping to raise my pH slightly and keep alk and calcium up in check (I keep it around 9 dkh and 425 Cal). The kalk may have raised the pH from 8.0 to 8. 2 over 24 hours period, nothing drastic. So, I didn't know if it was this, OR the other thing I saw, a few bugs.
The zoa frag just below my sunny D has a few of these bugs, which I think are nudibranches (hard to see in pic), and I did see a couple on the sunny D. To help the situation, I gave a freshwater bath, for about 5 minutes to each zoa to get these off them and the rock they were on, but the most the sunny D did since then is about 2-3 poylps open about 50% for half the day, then all shut again.
Do you think it was the bugs, or the kalk that made this start happening. Any ideas? I would love to see these Sunny D's back like they were before.
