Bubble Tip Help

[sdavi66572]

I bought 2 bubble tips about 3 months ago. They were the size of soft balls. 1 split so I have 3. The last month or so all 3 have shrunk down to the size of a quarter. The tips are pink on the very ends but most of it is white or translucent. Not sure what is going on. I have 3 radion gen 4 on my 220 gallon tank. My setting on my lights are set at 60% intensity from 11:00 am to 10:00 pm. I have a slow ramp up during the day.
Phosphates .04
Nitrates real close to zero
Calcium 370
Magnisium 1200
Alkalinity 10.4
Salinity .125

Sounds like they are bleached. Do you have any other corals in there with them?

Yes, I have a couple hammers, toad stool and a few other LPS. Everything is doing pretty good.

Can you move it to a lower spot?

I have tried to move one of them down lower. but he decided to move back to the top. Yesterday I dropped my light intensity from 60 down to 35.

Could a entrusting sponge be the problem
