I'm looking at options for producing RO water and the 4 stage RO/DI option is $50 more expensive than the 3 stage RO. What difference does that DI make? Is it worth the extra $50?
Bear in mind I'm not planning an SPS-dominated tank, but will want to keep a few if I can, in addition to LPS, softies etc. If the RO filter does all I need I'd like to save the money, but for want of a few dollars more, I don't want to start my next tank with a bit of a handicap that I will regret.
