mo: your second post...uhm...you just repeated what I had just said...why? That's exactly what I said. You just added the word "ever" to the statements. Same difference. Your argument can be sad for a lot of stuff...just because it's omited. But again I refer you to the specificity of the need for GFO still. Why be specific on one count and vague on the rest. I'm not buying it.
as far as my WC's. I have yet to see evidence that I am destroying the populations of bacteria. Many nano tanks thrive on near 100% WC's. Calfo has proven that this is a viable method of keeping marine tanks healthy. I'm not cleaning the BS, and I'm only changing the water...so the bacterial populations in the sand, rock, sump, and reactor are all untouched. I'm just removing water to reduce the the NO3 levels. (understandably though, some other stuff is removed, but the benfit out weighs the cost)
lastlyl try to remember that I'm doing this till the supplier tells me to stop. They and I want to see if a case like mine can ever get these to work. If it were JUST up to me I would have probably stopped them by now. But at the same time, now that I can get a bacterial bloom in just the reactor, gives me hope that one day they will wrk in the whole tank.
