I did not intentionally participate but on azoox.org TOTM thread I mentioned that tank with high nitrates >25 ppm may
consider this approach as part of solution and here is response I got.
I was linked here by RB yesterday.
It is a wonderful system, but I also wanted to share some information with you that might not sink in right away. With a bacteria driven system you are attempting to replace the work of algae/bacteria in natural environment with bacteria alone. Here is a technique to consider as well that is very effective and quick at reducing nutrient levels and does not require additives or much equipment, that only requires weekly cleaning and has the potential to add food back to system in form of DOC and copepods. Even if you choose this is not for you it certainly should be considered for these types of tanks. The ATS will remove ammonia nitrites and nitrates while sustaining copepods. It also supplies sugars from leaked DOC that will promote bacteria. It is slightly controversial in that if improperly maintained with weekly cleaning it will not be effective.
and one of responses
[quote:sm0xz82e]^ IMO an ATS scrubber big enough for an azoox system the size of Mike's system will just be an extreme waste of space time and money with little to no benefits.
I'd hate to see this thread become an ATS scrubber vs. other methods thread. Maybe you could start a separate thread in the filtration forum and we could discuss it there?
