ok so i just built a wet/dry fuge combo out of a 55 gal tank to replace my fx5 canister for my 90gal display i have had it running for 3 weeks today and havent put the mud in yet because the lfs has not got the figi mud i ask them to order for me. well today was looking at the figi mud directions theny say for an established system to add 2 spoon fulls a day my question is will it be ok to add the full 12lbs at one time.
