This evening three corals are white or nearly so as no polyps are visible. Monti digita, Pocillipora, and rainbow monti. The Sunset monti is not full on the edges, and the setosa looks normal and has been growing since adding. I completed a water change last evening. I usually check Mg and dKH before and after as I have been working to bring them up and in the last two weeks find the daily dosing amount.
dKH this morning = 10.2
dKH 8/15 = 10.2
dKH 8/9 = 9.9 ( two hours after previous water change)
I have been dosing 16ml alk two part for almost two weeks. and the number is holding to rising slightly.
on 7/20 dKH was 7.7
Mg this morning = 1300
Mg 8/15 = 1300
MG8/10 = 1260 ( two hours after previous water change)
It had been climbing from MG 1110 on 7/20
The new water last night was lower salinity than I usually add at 1.023. SG is 1.023 or 30ppt currently. It usually stays around 1.024. I calibrated the refractometer last week and made a very slight adjustment.
Another recent change is adding a mandarin Dragonette, and a Coral Beauty Angel in the last week. The timing to add both after only a pair of Rainford Gobies in the 50 gal total volume system may have caused an ammonia spike/ mini cycle. I will have to go out for a nitrate test kit as mine ran out on last weeks test. It was very close to 0 then.
The photo is the damage on coming in the door this evening. The rainbow in the center right was closed a couple days ago, and I thought it was due to light so I moved it to the center top where it was starting to open again last night and this morning. The sunset, left, has closed edges.
The last notable change in the tank has been the decline of the xenia colony that had grown from two heads to about a dozen. I moved it months ago to a slightly less lit area on the outside of the overflow box with more flow. It slowly went down. I do not want it if it cannot live where it is so I have just let it go, and removed heads as they turn loose and drift on the bottom. One small bud where they used to be, seems OK pulsing and is growing very slow.
Any ideas what is causing this? I am off to get a NO3- test kit.
