I am in the process of cycling a 10 gal and 5 gal tank. Fish-in. One fish in each tank. The 10 gal has one live plant in it. I set the 10 gal up in Nov. Then during that month I removed the fish to treat with epsom (not realizing I could have treated the 10 gal) so I think any cycle that may have started, probably was restarted. Anyway... Every time I test my water, both tanks - the tests always come back the same. Nothing has ever changed in color. Never really see a concern with the ammonia or nitrites. I do a weekly 50% change either way. But do you think I should be worried about my test kit being bad? Is that possible, even though the expiration date is well into the future? Purchased from Petsmart, its the API drops test kit. Per recommendation on here. I just find it weird that nothing is showing up. Technically my 10 gal should be close to cycled, it has been about 6-7 weeks since I put the fish back in... What does everyone think about this?
