It's typically dosed in general, but if you're getting a ton of GSA, you want to raise your level. I keep mine at about 2ppm. I still get a little bit by the end of the week, but it's not all that bad... I mean, I'm gonna clean the darn glass anyway...
Any particular reason you're doing the split photoperiod? Maybe try 5-6 hours straight, instead.
The split photo period is based around my need to want to see the tank when I am home, which is rarely between 12 & 2 PM, hence we run 8 hours with a break in the middle of the day when we're not there.
I'm still real fuzzy on EI and could use a link to a thread, or a lesson, that explains it so I can begin dosing macro's effectively...
Do you know anyone that knows this stuff? ;P
