I guess I'm odd man out here I used Red Sea for years .. A I just got a Mag and Ca kit not long ago I have all Salients at the shop and I compared one to the other and they all came in with in a drop or so of the other . I used to like the oder R/S for ease of use But I never really had any test that I had to depend on really .. DKH Ca and PO4 and Mag is all I ever test for anyways . Not sure how they stack up with ammonia and NO2 and NO3 . As I never use these test.. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
