I think there are a couple of things we need address before we can compare info regarding nirate levels.
First off the test itself. I have found that drop kits are, in general, very unreliable. Many of these will not measure any lower then 12 mg/l Last summer I tried doing 30% water changes a day. Nitrate levels in my tap water are 0.9 mg/l. On the drop test I used is was supposed to be able to measure down to 2 mg/l. I consistantly got reading around this level. However when I cross checked it findings with a Hanna tester I was running 10.7 mg/l.
It's easy enough to say I have a low reading but that is useless if we all use different kinds of test kits.
Now I notice that Nurse Bishop is reading 7mg/l with her Bakki Shower. Shiro must be doing something right.
