I was told by my lfs that a test kit, after opened, only tests accurately for a year. Is this true? I looked on my box and I didn't see any date on it.
Yah, this lfs has always pointed me in the right direction, but test kits are fairly expensive and I'd rather spend the 70 or 80 bucks on a couple new corals, you know? Just thought I'd check with you guys before investing in a new kit. Thanks.
