Advice: Unhappy tank..

[ghztew]

You're correct Pegasus, I'm using a Hagen test kit. Looking at the conversion tables etc.. my dKH would be what you posted 6.72.

So...... what does that mean? :confused: Is this high/low/on target?

I'll keep reading up on the Alkalinity, but if it is possible that the coral was bleached, will it return to it's normal colour over time? Earlier today when I was studying the coral I also noticed that some of the tiny hairs on the coral are slightly brown/tan while the rest of the coral is pure white.

If I can grab a digital camera, I'll post a picture.

Once again, thank you for the time in helping me out..
