di water

  1. General Reef Discussion
    Well pretty much the title says my predicament. My LFS stopped doing the RO/DI water due to lack of sales vs. cost of making it. and literally it was the only one that sold it. so now I'm a bit up the creek for that. So I'm looking for alternatives. Thank god its only a 10 gallon nano tank...
  2. The THINK Tank
    High all, I was doing a test at the shop today and was making water in the 17.5 mghm range. Is this too pure for the reef tank? Thanks for the input.
