I have an API test kit, like new for sale/trade. I used it for cycling my tanks, but I rarely used it and haven't used it in a while. I bought it in October, and only did minimal testing:
Nitrite is still sealed, others have been used for a few tests.
I'm looking to sell it, as I need the money for my tanks, but if you have any plant trades I'm willing to barter.
These go for $20-25 online, but as this is slightly used not sure what to charge... So make me an offer!
Thanks for looking
