If you add it to 60 gallons of water, 60 gallons * 3.78 L / gallon = 226.8 L
0.6 grams / 226.8 = 0.26 mg/L
Ummm, why am I figuring this wrong?
(2g/100ml)*30ml = 0.6grams in 30 ml at 2%
0.6g/226.8L= 0.002646 g/L
multiply that by 1000mg/1 gram= 2.65mg/l
Why were you getting 0.26mg/l? Where am I doing that wrong?
2.5% solution (what i have) is 2.5gram/100ml, or 25000mg/l.
1ml of that solution is 25mg/ml. Adding 25mg to my aquarium, ~100L, is .25mg/l for my aquarium? Is that math correct?
