Hi Folks,
I am on day 19 of a fishless cycle. On day 7 I tested for nitrites and found them present. On day 14 I tested again and found the nitrites to be be above 1
PPM. The test reading on day 14 was dark pink-red which is the highest reading on the card. This morning (day 19) I tested again and the color was a light orange. There is no orange shade on the chart at all. I tested this twice to ensure that this was not an error on my part. I got the same result both times.
I am using a Red Sea
test kit that has an expiration of 9/11.
Do you think an orange is just high levels of nitrites beyond what the kit can test?
Any thoughts would be greatly appreciated.
David
