Sounds like your doing pretty well!

I was also wondering about the test itself. Mine is Red Sea---Ihe ammonia
test always starts yellow (good) but ends up at .25 after the directed 15
minute wait.Theres also 19 total drops of chemical to be made into the test
tube. I`m a total novice----but these factors seem like they could leave a
lot of room for innacuarracies.
Is there another relatively inexpensive test kit that leaves less variables
to human error?
