Stability Sucks man... Yes i always shake the bottle before dosing.. in 7 days didn't convert any ammonia to nitrite.. ill just use the feeders as source of ammonia now, i used household ammonia 10% NH3 in water solution. Not going to use anymore.. i already introduced filter material from a established fish tank, so shouldn't take too long to cycle this tank.. i also ordered Prodac Nitridac:
"A liquid high concentrate of non-toxic bacteria (40 million bacteria per ml) carefully selected for their capacity in breaking down organic matter and for transforming ammonia in aquariums. This product can be used in new or existing fresh and saltwater aquariums to transform highly toxic ammonia into nitrites and nitrites into nitrates. Nitridac actually causes the rapid degeneration of organic compounds reducing the build up of sediment or mud, restores aquarium walls and beds preventing the formation and growth of algae and also prevents an increase in nitrites."
Ill try this one next week if i dont see any changes in the ammonia or nitrite...
