Alkalinity sink

[SuperFudge]

hey Steve,

That is actually not a bad alk consumption at all if you have a good load on the system.

My last 150 sps system consumed almost 1.5 meq/l or dkh ( i dont remember wich units..what does salifert test in ?) a day (with a heavy coral/fish load).

I believe Jamies consumes about the same.

I noticed this originally when my bottles of co2 needed changing and the reactor was off the system for a day or two. Then during future changes i could always guage consumption.

More Alk Consumption in my opinion, just boils down to really good coral growth and/or more pollution.

Another thing i noticed, but didnt understand...is that it seemed to level out after about 2-3 days, and remain almost stable but very low alk..like 2.0, its almost like at that level, the corals possibly didnt do much growing therefore not much consumption.

Marc.
