I have recently started a reef tank, and was giving some bottles of ESV B-Ionic 2 Part Calcium Buffer System from a friend that purchased a reactor. The bottles are several years old, so I was wondering if this stuff had an expiration date? The date tested & filled (Lot Number) is 041202. Would this work, or would I be better to purchase some new bottles?
