NITRATE FILTER PROJECT UNDERWAY

thats the theory, the only reason for water changes is to lower the level of nitrates, (and of course to eliminate disease) but disease can be avioided all together by quarentining new fish.Onion01;1613727; said:

there will still be build up of minerals and dissolved organic compounds...........carbon filtration will help and smaller water changes

DOC maybe removed with carbonminerals which are non polar will not be removed
mechanical has no affect on dissolved solids or doc ....
let me know if this is not correct....john
There will also be no trace elements left if no water changes. They would have to be replenished.
look into Rainsoft water softners. they use a carbon filter to remove 99.99% of disolved solids. (i know this to be fact as i have worked for the company). admittedly there is also the "top Secret" yellow bead.
minerals are just disolved solids. so they fall into that category. .... The Georgia aquarium does no water changes. been open for several years.
trace elements are like water. every drop that started on this planet is still here. evap, rain, ect you know the water cycle. They are the same in your aquarium, theuy are not going anywhere. saying they are woud be like saying your salinity is going to drop over time. .... it will not, with the exception to salt creep (this example of course applies to my expertise of marine ecosystems.

Carbon filtering
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Activated carbon from a water filter used for Carbon filtering in powder and block form
Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media. One pound (454g) of carbon contains a surface area of approximately 500,000 m² (125 acres). This carbon is generally activated with a positive charge and is designed to attract negatively charged water contaminants. Carbon filtering is commonly used for water purification, but is also used in air purifiers.
Carbon filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. They are not generally effective at removing minerals, salts, and dissolved inorganic compounds.
maybe ion exchange resins or chemical filtration ???
