Hammer not extending anymore

[zedoita]

Hi,

I have a hammer that used to look really good, but started "shrinking" and not extending over the past couple months.

Parameters from March are almost identical than yesterdays:

Temp 78.3

Salinity 1.025

Nitrate 10

PH 8.3

ALK 9.5

Phosphate 0.02

Calcium 460

Magnesium 1320

Posting pictures and video below. The frogspawn that was right next to it is doing very well, growing. I moved the hammer to the sandbed after I took him out and dipped in coral rx while I was dipping other corals. It did have a vermetid snail growing on its base which I removed. One of the new corals I just got was the torch on the video below which seems to be doing well.

Anyway, is there anything else I can try? I tried moving it down, changing the position it is at for different flow, dipped in coral rx, nothing has helped so far.

Thanks in advance!!!

Your water parameters look really good - along with your flow. It's entirely possible it wasn't happy with the light, snail or some combination thereof. Since you have other euphyllia that are also doing really well on the sandbed, I'd be inclined to leave it where it is and just monitor over the next few days to see if it improves. You could also (temporarily) dial back the flow just a bit to see if that helps.

Phosphate .02 is low IMO Test kits are not that super accurate and have a range of error. .02 could easily be 0. Slow shrinking over months time to me says.. starving.

@Shirak, thanks for the reply. If it is indeed starving, would it benefit from some target feeding? If so, any suggestions on what to feed it?

I feed target feed mine. They are in a fishless tank so all the corals get fed. I find the hammers and frogspawn are slow eaters so flow pumps get turned off or down considerably for about 30 minutes. I use a variety of things from LPS pellets to small (1mm or less) fish food pellets. I also use frozen mysis that I chop up while still frozen and occasionally things like oyster feast or broadcast reef chili/benepets reef food. I usually feed a few times a week, mostly at night after lights out for an hour or two. Sometimes during the day.
