Cobalt Anti-Phosphate is a high capacity resin that will rapidly remove phosphate
from your aquarium water. Anti-Phosphate is safe for fish and invertebrates, but care should be taken when using with planted aquariums, phosphate is a key nutrient required for plant and algae growth.
Pre-bagged for easy use and replacement.
Contains 2 - 1.76 oz bags
How much can each bag remove?
1 bag can remove a total of 0.6mg/l phosphate in up to 26 gals aquarium of aquarium water in about 10 days.
This means for a 100gal tank with phosphate of 0.6mg/l you would need 4 bags.
If you have lower phosphate levels or if you have less water you can adjust the bag #'s
for example, if you have 0.3mg/l in 100 gal you can use just 2 bags for same effect.
If you have a 75 gal tank with 0.6mg/l phosphate, you will require 3 bags.
