    Has anyone heard of RO/DI units made by H2O Science, available on Ebay. Do they stack up to the Coralife Ro/DI units?

    REEF RO DI WATER FILTER 75GPD AQUARIUM REVERSE OSMOSIS - eBay (item 230380436294 end time Oct-22-09 05:42:36 PDT)

    Also will any Filter replacement work for this unit? Say I went to the LFS and bought new filters/membrane from a Coralife? They look so similar, here is the coralife I was looking at. They are just canisters that you buy new cartridges so I would assume they are the same type?

    That price on the H20 Science is pretty good. The big difference is it says the H20 Science is a 4 stage? not sure what the Coralife is, and the H20 Science flows 25 more GPD than the Coralife. Which makes me wonder if its filtering as good...

    I was also looking at this unit as well...

    Yeah, Desertrat knows his stuff when it comes to RO/DI. I just ordered my ProPlus from the link he provided, 168 shipped. It was a little more than I wanted to spend but what makes it worth it is the TDS meter, high quality filters and resin, and pressure gague.

    If you were to buy the H2o science one you mentioned and a tds meter it would come out to roughly the same amount. So basically your getting the premium filters at no premium ;D

    Tatted,
    I would ask them to eliminate the 5 micron carbon block and replace the 5 micron prefilter with a 1 micron or less. You should not have to use a carbon block as a secondary prefilter if you have a good prefilter. In that case a single carbon block is more than you need if the prefilter protects it, even with chloramines. If you keep the empty housing use it as a second DI filter not a second carbon, waste of money otherwise.
