Hi Mikro -

Can we get more info?

- How long you have had the coral
- How long it has been having problems
- The rate at which the problem is occurring/spreading
- Any changes to the tank - equipment, additives, new livestock, etc.
- How long the tank has been set up
- size of the tank ( gallons or liters)
- nearby corals

Water quality:
- pH
- temperature
- salinity
- nitrate
- phosphate
- alkalinity

Tank information I care about :
Lighting - 2 x 65W PC or 400W MH is fine
Water flow - number of powerheads/pumps and the flow rate
What you add to your tank on a regular basis and how much

Tank information I don't care about :
The brand name of your skimmers, light bulbs, pumps, spectrum of your lights, if your tank is a bowfront, acrylic, starfire, etc.

A clear description of your problem.
- what it looks like - analogies are helpful.
- size of any lesions or areas
