[AquaticLife] Question about Nitrate Level
Are you using hte API test? Because it’s possible to read several different levels on most of their tests depending on how you hold the tube to read it. On the nitrate test, I often find that if you hold the tube off the card or look at it through light it looks like 5.0, but if you hold it right up to the card it looks more like 10.0.
On the ammonia test I can’t tell .25 from .5 and can’t tell a level greater than 0 from .25, and some times I can’t be sure if I’m loking at ..25 or 1..0, and I’m not the only one I’ve seen say so.
The Tetra tests are easier to read but reputedly not as accurate, In my experience they sure don’t give the same levels that API tests do.
