Hard corals dying

[mcelvain]

HELP!! My hard corals (open brain, galaxia, and birds nest ; so far) have disintegrated right before my eyes. Have tested water parameters, done a 30% water change, drip Kalkwasser, add iodine strotium/molybdinum and iron.
My soft corals, fish and invertebrates seem unaffected. No answers forthcoming from LFS. I need help!

:notsure:
Not by any means a expert here but maybe insufficent lighting

What is your lighting? Most hard corals, especially sps need MH or T5's.

also how are your alkalinity and calcium levels

If MH bulbs you might need to change them due to age of the bulb

I have compact flouresecent 65w 10000k x 2 and 65w actinic x 2. My open brain had lived in this light for 2+ years and I had replaced the bulbs about 3 months ago. I haven't done a calcium level test but I always drip Kalkwasser for water replenishment.

You should never add ANYTHING without testing for it first. You may want to get a calcium test to make sure you are not over dosing or under dosing calcium.
