I´ve having a few problems with my phyto cultures. They don´t get dark as they used to.
My method:
- Fill 1.5 Gal botles with fresh water (200 ppm, Tap water)
- Add FAF fertilizer. I get a 700 ppm reading so it´s 500ppm of fertilizer.
- Add salt to get 1018.
I Tried adding more fertilizer to have 800/1000 ppm of fertilizer but I´m not sure if it is correct.
How many ppm of fertilizer do you have in your cultures? I don´t want to add too much because I co-culture rotifers and ocellaris larvae and having too much fertilizer will make me add amonia to the tank.
