We have it in the water here in New Braunfels. I should have researched it a long time ago but thought that our water couldn't be much different than in San Antonio. Anyway, will a regular rodi unit filter the chloramine? A saw a special unit on BFS but wasn't sure if it's 100% needed. I'm seriously just thinking about using tap water and prime this time around. Considering that I'm going to have a large fuge, the extra nitrates may be desirable. Never thought I'd say that!
