Galaxea Coral Help

[invaderzimm]

So I just got a Galaxea Coral for my tank. It is one of only two corals that are in my 30 Gallon tank. The other coral (also an LPS but I forgot the exact name) is doing excellently and opened within a day of putting it into my tank. However, the Galaxea coral has not. It was fully open and green at my LFS and was under full light. It has remained closed now for 5 days. I have a 25 W, 25000k LED light. Ammonia, Nitrates, and Nitrites all seem to be in check and the sg is at 1.022. It is set by itself without anything near it. Why isn't the coral opening?

i think you need more lighting.....they like moderate lighting.... and med flow....

25000k is very blue, usually a 14k is good or even 10k. Your Salinity is more adept to a fowlr tank, try and get closer to 1.026. Am/ni/na need to be 0 without exception. If your light is stronger than your lfs lighting, you should have light acclimated it over a week or so. Check phosphates as well, anything over .03 is unacceptable.

I agree more light 14k is a good bet and move salt to 26 gradually over a few days

Thanks for the replies. Would you say this light is too blue or too weak for the galaxea? (or both). I have the receipt and box, so I will probably take the light back and get one closer to 14k.

Do you have any more specific information on the light you have? Can't say much without that, not to discredit you but i find it hard to believe you have a 26k light lol. I think a mistake may have been made Never seen anything above 20k commercially.

It'd probably be a good idea to post a bit more info, like the dimension of your tank, length, width, depth, and what corals you are thinking/planning for going a year forward or so.

I've still a bit to learn about LEDs, but a lot of members are pretty versed on them and can give you some specific suggestions with the above info.

And it'd be good if you could give the make and model of your current light, any info that's on the housing/box.

Ok here's more info. The Corals in the tank are a frogspawn (which is regularly open) and the Galaxea. The tank is 24 inches across the top and 30 gallons. I have glass on the top of the tank and then the light. Yesterday, I removed the glass and the Galaxea partially opened. And yea it is 25,000k.

That's very helpful info on the light you're using. That light could work for a fish only system but let's look at some more powerful lights for a system with corals, like the galaxia and frogspawn and other LPS corals, or polyps, or anything.

If you want LEDs you can get one of the more generic fixtures imported from China via the internet or an LFS. They can cost between around $50 to $150 depending whether they're new or used, etc - and look like this (here's a used one posted on RC):

And they go up from there with many more features and the cost will go up accordinglyl. Other members know a lot about this stuff so maybe someone will chime in. But in either case one of the these "box" fixtures would work well over a 30g high tank which sounds like what you have.

Thanks for the help again. I think the box might be labeled as the max color. The light has two settings, a full brightness, full spectrum white light (produced by red, blue, and white LEDs) AND a 25000K extremely blue light. I rose the salt level and it partially cameo out, but went back in soon after and still has not come out. I moved it closer to the light and still nothing. What else could be causing it?

spec grav is a bit on the low side. try to increase it with water changes and that may be the trick. could be as simple as that
