more newbie type questions...
1) what is everyone's thoughts on the need for an R/O unit in Calgary for a nano reef tank? must have or nice to have?
2) does anyone have any feedback on the differences between the following types of R/O units? are barebones style alot more maintenance but worth it for the higher % of contaminant removal?
Bare Bone TFC R/O Unit
Full Size TFC R/O Unit
once again, thanks for the help
