Hi edfkbf
To Reef Central
WOW! Am I impressed; a potential reefkeeper who has been on the board for close to four years and makes their first post on my thread. I will try to give a general idea on costs like I did in this article but it is best to shop around and see what are advertisers are charging. Back when you first joined RC a RO/DI ran almost $600. Now you can get a pretty good one for less than $200.
Hi Shin
Not with a RO ahead of the DI. An RO filters molecular sized particulate matter, even something as small as a virus. Since the water reaching the DI is fairly sterile there is little chance for a bacterial slime to build up and coat the resin. Your demand should not influence resin life.
Voodude,
If you can afford a Porsche then forget what I told edfkbf
and buy a $600 DI unit.
