R/O unit kenmore elite

The price is "ok" but it is only RO and not RO/DI which is really what should be used on a SW tank IMO (RO is acceptable for Fish Only but still RO/DI would be better). Personally, I would prefer spending $150 on a really good bulkreefsupply RO/DI unit and know that filters/parts are easy to obtain and it is very easy to add on additional canisters should you feel the need. I run a 7 stage myself, 5 stage unit with 2 extra canisters. It even states in that link that the filters need replacing which is the majority of the cost anyway. I just replaced all my filters last month and it cost a tad over $100 to replace all of them.
