I just got one last night from a friend who got it from his friend and i jsut want to know how much of the phosban goes into the chamber? i have everything hooked up and ready to go but i dont know how much phosban to put in it.
it should tell you how much to use on the phosban. but i beleive it is 1 gram per gal. i have never heard anything about not using less than 130 grams. i use 100 grams in my 75 gal. tank/ 30 gal. sump/fuge
