ok I guess non of you realy read the website
they are claiming that by using osmosis they put the tank water on one side of a membrain and the good fresh water on the other sie. there claim is that the inpurities travle through the membrain and equilize between the salt and fresh water and then you dump the fresh down the drain and do it again. then they add salt ect as some is lost in the process.
My statment is that they are misusing tearms and confusing me on what they are actualy doing.
so by there defination this system should be adding water to the salt warer lowering you salenity because the fresh water low polution will actualy flow through the membrain into the more poluted water. the polution will not flow through the membrain. so what they are doing is diluting the tank water then adding high concentraition of salt water to bring the salinity back where it should be and at the same time dumping some water down the drain so they don't overflow the tank. this is not removing any bad stuff in the water except for the small amount that goes down the drain, other wise they are relying on the filters in the set up to do the work.
her is the actual defination if you want to see what I mean
"From Wikipedia, the free encyclopedia

Osmosis is the movement of water molecules across a semipermeable membrane from a region of low solute potential to an area of high solute potential (or equivalently, from a region of high solvent potential to a region of low solvent potential). The partially permeable membrane must be permeable to the solvent, but not to the solute, resulting in a
pressure gradient across the membrane."
so I guess my problem wasn't with the product and sorry if it sounded like that, but rather with the poeple trying to use scientific tearms to make there product sound even better and magical.
they also say you still need a skimmer, and mechanical filter, so this now makes me start to question there product and if it is anything more than a glorified water change.
