bubble coral

[TriMax]

I have, what I think is, a fairly large bubble coral. Is it possible that it likes salinity of 1.026-1.028 more that 1.022-1.025? It has started, for the last week, looking kind of "shrinked". All that I know has changed is that I dropped the salinity faster that I should once or twice and I added a blue tang. My daughter thinks the blue tang and the purple tang are doing too much swimming and unsetting the coral.

It could be if it dropped fast however a pic would be most helpful. Notice any tissue issues? Are you seeing more skeleton?

 

[TriMax]

No "tissue issues", I think. No skeleton. Just shrinking like it does every night when the lights go off.

What's your calcium, alkalinity, magnesium? I had a huge bubble in there with Priscilla and Linus and neither one was able to bug that coral at all. I would also strive to keep my salinity stable at 1.025 if at all possible. Most corals don't like lower salinity, I believe.

The bubble looks fine tonight, but my Alk and Mg do not. I will need to spend a week or so raising them slowly

CA -- 420
Alk -- 2.5 or .86
Mg -- 1005

I had not tested before. Ok now fuss at me. Just got the BRS 2 part in yesterday. Will bring some of my water in to get it tested tomorrow to make sure my kits, probably old, are giving me good numbers.

Go REALLY slow with your Alk... I wouldn't raise more than 1 per week... But thats me...

Yeah, go slow. I didn't and it costed me alot. :cry:

update on the bubble coral

It seems to be doing fine. I think it must have been the swing in salinity. I know better, BUT..... Will definatly try to avoid that in the future. Need to raise the other water chemistry parameters, too. What I got on the tests and what the LFS got are not close at all. Not sure what to do.

I think I may get a quart of tank water and test it and take the remainder to LFS for testing. Hoping the result will be closer together. :wink: I think both mine and the LFS test kits are old. Not sure how much that matters.

 

[macclellan]

Compared to everything else, quality, non-expired test kits are cheap! I'd trust that over what you or an LFS gets with expired kits, especially if there is a significant discrepancy between them.

 

[EvilMel]

We don't use frickin' expired kits...unless there's nothing else and then we TELL you that it's all we had.
