Does anyone know how long you need to apply this in order to bring phosphates down from 0.25ppm to a normal level,whatever that may be. 60 gallon salt water tank using 12.5mm dose every 24 hours.
should say it on the bottle you got..but i used kent's phos sponge last week..i used have of what they said to use cause i have a smaller tank and it said not to leave it in for more then 48 hrs or it would leak the phos back into the tank
