Maybe this has been done before, but I need a project and have enough spare stuff laying around to do this. Would anyone be interested in a journal of cycling with different "bacteria in a bottle" products? I would use a control tank without any additives, one with Dr. Tim's, one with SafeStart, one with Stability. I only have four empty tanks, but I could do a same-sized rubbermaid container and use a 3rd product - maybe Nutrafin cycle? I'd then do daily testing and document how well they all work. Or does anyone even care? I'd have to buy a couple more sponge filters so that I'm using the same filter in each tank, but I am willing to do this for science!!
