Luke,
I do appologize for the late response. Some factors beyond my control make every second week rather difficult for me to operate on any level let alone have an in depth conversation. Again... I am sorry.
"What makes the system unique is that it combines an
outside power filter and rfug filter, and most especially that the "towers"
provide an environment for bacteria to convert nitrates into nitrogen gas making the eco-magic tee first aquarium filter system to complete the nitrogen cycle."
Unfortunately that is not all that unique. There have been a few systems on the market (most come and gone to my knowledge) that have advocated using similar methods with similar medias. In point of fact I can think of at least 3 shops in my area that use an almost identical "tower" design for their central systems. So far as completing the nitrogen cycle... not so much. There is a less known system that if maintained properly works wonderfly in freshwater. The NNR or Jaubert Style Plenum. The down side to the media that is in your system is it is suceptible to biofouling on the surface which quickly makes anoxic conditions anerobic. If that happens you start running into issues with ammonification. IE, those condittions you were refering to that wouldn't support fish form in the interiour of the media.
"The problem with phosphates is that in large quantities they can cause an algae bloom. In freshwater having lots of good fast-growing plants uses up the phosphates. However, we are basically suggesting that the EM should be used for a fish only tank -- and with only fish phosphates should not be a major problem as they are with inverts and reef tanks in general."
Very true. That said though I have seen more than one person leave the hobby because of excessive algae growth so treating it cavelierly would be detrimental to a company that wants repeat sales. Also, how do you recommend removing large amounts of algae with out water changes? Phosphates aside, what about the DOC's and in specific Hormones? Are you aware of the biological process that stunts fish growth? It starts with having healthy fish releasing growth inhibiting hormones. If those are not removed (normally through water changes) the fish stops growing externally but it's eyes and internal organs do not. They continue to grow until they are fatally damaged. You know, skip the DOC's... I just want to know how this system deals with hormones.
So... it is Heterotrophic bacteria I take it? While no, "reverse" nitrification (ammonification) was not my main concern, like I said above it could be an issue in the tower media. What I was refering to is the exact same reason that Cycle (and most other bacteria based products) do not work as advertised. The het's are responsible for breaking down solid waste into liquid waste giving the illusion of a "clean" tank. The risk is that if the dosing regime is changed or missed there could be an increase in NH3/NH4. The actual nitrogen fixing bacteria (Chemolithotrophs) are quite sensitive to excessive NH3/4 which could be produced then. The basic effect would be a "mini" cycle in an established, stocked tank. Never a good thing... (BTW, I am aware that at least one cycling product is from the Detroit water treatment facility and it is used for solid waste... It wouldn't suprise me if more were too)
"Unfortunately I cannot send you a filter system for testing without you representing an organization."
And
"MSDS information is for employees’ only upon request. They are only required to be disclosed when dealing with things containing hazardous materials."
That can be arranged... I still have a few friends and many contacts in the industry. Plus I have been thinking of a part time job for a while now... Seems like a good time I guess
. Do you have any Canadian distributers at the moment?
Thank you for your time.
