SPS frag swelling??????

[Chaloupa]

I have had 2 Mille's do that..then followed the tissue.....hope it's not the same thing happening...

Its the tips starting to burn. Had it on my Green Tort recently.

Think of it like a blister When you touch it, its soft like jelly.

Place it lower in the tank.

Interesting thought but it's only under one white and one actinic T5 bulb, and the light sits about 7 inches above the frag. What you're saying seems to make sense but with the light I have I don't see how it's possible, I've actually been wanting to buy MH 250 watt lights for the tank because I figured the 2 T5 single bulb lights weren't going to be very effective for the long term.

However I will try placing it lower and see if it helps.

U didn't take any water from Dez's Tank did you if that is true your SPS are on Steroids lol

Actually yes, the frags came from him.

Hi,

Any Acropora can burn if its placed under lighting thats its not used to. Did you recently add the frag? If so it's best to place it on the bottom for a few days first and then gradually raise it to the desired position. I have burn't acro's before under T5's the PAR can be surprisingly high.. On another note, the tip burn might be from a parameter & not the lighting? Such as Potassium or Alk/Dkh Swing.

BTW if the tissues starts receding, it would be best to clip the affected area off.

Hope this helps.

I got that frag last weekend, however it was under 250 watt MH light which I would think would be more par then my T5 light. The tip isn't burnt it's just swollen like a bubble, and I don't think it has anything to do with parameters because none of my other sps frags seem effected. All the polyps are out and the tissue hasn't receded, so I'm hopeful it will be ok. I did place it lower in the tank and it seems to have helped, the bubble on the top of the branch of frag is still there but the 2 underneath seem to be almost gone.

I had both 250w MH and T5's running on separate tanks and the T5's were providing more Lumens than the MH. (T5 tank was shallower)

Most T5's over shallower tanks & closer to the water can easily burn a coral if not acclimated correctly. I agree that's it unlikely a parameter if the other corals are doing fine.
