Aquatic Life T5 HO

[missy56]

Hi! I have a 55 gallon aquarium with a 48" T5 HO from Aquatic Life. I have not changed the bulbs yet because I have only had the system since April. My tank has been established since May 2010 and I have always had a T5 HO.

Currently I have 2 leather corals, zoanthids, frogspawn, and a candy cane coral. My candy cane coral has always been in the same spot and was looking great until about a week ago and then it started receding.

None of my parameters have changed and my alkalinity and calcium have been great.

Any ideas on what could be happening? I lost a blasto coral last month and don't want to lose my candy cane as well.

Also, would you recommend changing the actinic bulbs from the original bulbs?

I would go with 2 ATI Blue Plus, 1 ATI Purple Plus and 1 KZ New Generation for the new bulbs.

Check your phosphate levels, that could be the problem. If you have not done so yet do a water change and have your local fish store test your water. If your lights are that new, you probably do not need to change your bulbs. This is why I think there must be something wrong with your water parameters. Best of luck.
