Orange, sulpher smelling effluent

[Jboy]

Thanks guys....

wow, I am no chemist, so you are losing me a bit. I am measuring the PH with a PH monitor attached to my Neptune Aqua contorller II. I have calibrated the PH monitor with solution, and have also tested the PH with a test kit and the results are confirmed.

The Tank PH is 8.13. Now it's beena while since I actually confirmed the PH monitor readings, but for right now, let's assume they are correct.

Darren, i think you might be onto something, for altough my corals are doing fine, they are not growing, and I am not getting any corraline (sp?) growing in the tank. I have a 92 gallon tank.

So here is a question. Assuming my system is anerobic, what settings do you suggest I try?

Thanks again
Jason
