I would replace it. I don't trust test kits that have been opened for longer than 6 months.

I knew that someone knew the answer, just too senile to remember who it was! :lol:MalawiLover said:According to API, the kits are ok for 3 years from lot number date (if unopenned) and good for 1 year from date of opening (but if you open it after 2.5 years, its still on good for the last six months.
I pretty much get a new kit every six months a well, unless I manage to find one that has only been on the shelf six month or less from bottling date (so far only happened once in several years).
