What nitrate is this?

Well I don't need to worry about that so you think the api is just fine? Just nitrates and ammonia and nitrite really, basically just nitrate

the way I look at nitrate testkits is that very few are able to pinpoint low range levels...
to me having from 0-5 is fine, 5-10 I have to be a bit more careful and more than 10 changes are needed.
Salifert is fine for this!
