I think that I have a problem!
After cleaning all the substrate, my ocd compelled me to clean all of the filters.
Since I have never cleaned all three at once, I figured that it might be a good idea to test for ammonia.
And the test showed about .25 ppm. I thought ops my bad, so I ran out to the store and picked up a carton of that white
ammonia absorbing granules, and a bottle of ammonia lock. I used all of the stuff that I bought.
The next day the ammonia was gone, did a huge water change the following day, then checked for ammonia and it showed on the test
So, I figured I was having trouble reading the test, so I filled one test vial with water change water that has been siting for a day, and marked the vial so I would not mix them up.
And I filled another test vial with tank water.
And what do I see,,,, the tank water showed no ammonia it was pretty much yellow.
But the water change water was showing somewhere between .25 to .50 ppm. it had a slight green tint to it.
Very obvious difference in color between the two test vials.
I ran the two tests again, using tap water from a different water change garbage can, and same results.
So my tap water has somewhere between .25 and .50 ppm ammonia.
I have a pretty big RO filter, I picked it up a while ago. But I really don't want to go that route.
Do I buy a 5 gallon bucket of those white ammonia absorbing granules?
I am really at a loss as what to do with this situation.
Also can someone recommend a better ammonia test then the API one that I am using now?
