Orange, sulpher smelling effluent

[Jboy]

Thanks darren,

O.K. So I'll up the effluent level to 75 drops/min, and leave the CO2 as is. Once the PH raises, I'll increase the bubble count to bring the PH back down to around 6.8.

I have forgotten right now what my ALK was, but i think it was around 12. Should I keep it at this level?

And does this sound like a good plan?

Thanks very much
Jason
