Fritz F/2 dosing

Fritz F/2 dosing

Just chiming in my exp. I've been keeping my Nanno cultures for a couple years now and seems to be pretty simple. I use led flood lights to culture mines and I think they are 6k. I started with a bottle phyto from Amazon. At first I was having problems keeping them long term with one of the F2 formulas. They would get dark green then crash really fast. I have since switched to fritz brand f2 and a little bit of Kent Coral vit. I've gotten lazy and let the cultures go for a month or so without touching them before they start fading. Anyways:
Algae: Nannochloropsis
Light: 10w led flood 6k
Ferts: Fritz F2 and Kent Coral Vit
Culture vessel: 2g drink dispensers
Salinity: 1.018-1.020sg
Water: Tap water

How much of the fritz f/2 do you use per gal? Also, do you use both A & B mixtures?
