my 10 gallon tank tested positive for ammonia (like 4.0). its a fully cycled tank, i keep up with regular maintenace (ie- 10-20% water change and gravel vac weekly). it has a power filter with carbon inserts. i added some 'kent first step' to the tank a few weeks ago, because i was out of my regular water conditioner. this product detoxifies ammonia, as well as conditioning the water- and it says on the label it may give a false positive when i test for ammonia. my question is; could the positive reading be due to the product that i put in the tank 2-3 weeks ago? i have done roughly three water changes since then. i am hoping it is still affecting the test results- and not that i really have high ammonia.
the inhabitants- 2 harlequin rasboras and 1 cherry barb- all look fine, no signs on distress or poisoning.
