Hello I just purchased a 25 gallon innovative marine tank and I’m getting ready to cycle my tank. I was looking to get the Dr Tim’s products for the fish less cycle but unfortunately my LFS no longer carries that brand. They ended up selling me fritzzyme turbo start 900 and fritzzyme Fishless fuel. I’m a little confused on the process of the Fishless fuel on the bottle it saids to dose 1tsp per 25 gallon. My question Is it a one time dose in the beginning or is it something I need to dose every few days like the dr Tim’s product?
