Hey all,
I am in need of some SPS help, I have been having an issue for about 6 weeks or so where I am losing my SPS frags one by one.
My tank is a little over a year old and everything was doing well.
It all seemed to start with a lighting change (seemed to I say) I had a Finnex 150 Watt DE HQI 14K with 2 24W T5 03 bulbs about 6 inches off the water and everything was growing well but not lots of color.
In anticipition of a tank upgrade I swapped out the Finnex light for a Luminarc 3 Stealth Mini with 250W DE HQI and no supplement lighting. I started 18" off the water and lowered 1" or so each week until it was 7" off the water. First my Green Birds nest started getting algae on on tip at a time and then proceeding to slough off all colored tissue. Then a purple Acro like a bali green slimer but purple with blue tips started the same progression until just a bleached hulk now I have a rainbow monti frag started a white spot on top and is working it's way down the whole coral.
These are over the period of the problem thus the from to

Here are my microscope shots these are at 40X
Sorry for quality trying to learn how to use this thing. just shooting with my wifes digital pocket cam thru the eyepiece.
These shots are of scrapings at the edge of the tissue where it's dying. I don't know if what I am seeing is part of the coral, Something attacking the coral or just bacteria eating the decaying coral tissue.
The coral tissue is covered with these red dots. they seem to be moving and some seem to be vibrating. is this my problem or just part of the coral? They seem to be single cell (in my microscope)
Sorry for all the horrible descriptions I am a computer guy and I think I was " busy" during biology class (damn!)
Can you see anything I should know about?
