| Re: An Alaskan Reef (38G) I like the new scaping. Definitely go RO/DI or at least RO soon. Soon as possible.
RO filters are 3 stage purifiers that go for $100-$250. The DI is a 4th stage.
RO/DI are 4 stage purifiers that are a bit better and go for just a little more.
Coralife ( good brand ) makes a 4 stage for about $130 witch is a good deal. |
