SeaTesT® Reef / Instant Ocean® Test Kits

These standard and reef aquarium water testing kits by Aquarium Systems are inexpensive, considered reliable and very easy to use, but inaccurate readings may result if the dry chemical powder reagents are used past their expiration dates.

Aquarium Systems has taken their ever-popular SeaTest® Reef and fasTesT® Saltwater lines of water testing kits and grouped them into one line, now named Instant Ocean® Test Kits. Nothing has changed about these products, except that rather than having to buy separate Ammonia, Nitrite, Nitrate, and Phosphate tests, these are now simply combined as two-in-one Ammonia-Nitrite and Nitrate-Phosphate kits. As before you can buy individual pH, Alkalinity, Calcium, and Copper tests, the combination Ocean Master and Reef Master multi-test kits, and reagent refills.

After many years of using these test kits under the previous fasTest® and SeaTest® names, we found them to be fast, accurate, and very easy to use. The wide-mouth and wide-base testers make it convenient to add the reagents, and they don't tip over easily. The color comparator chips slide right into the tester, and the colors are vibrant, which makes reading the test a simple task. Testing times range from 2 up to 20 minutes, so the results are quick. With the convenient individual foil packets, there is no worry about keeping the granular testing chemicals dry, fresh, and active.

Although we highly recommend Instant Ocean® Aquarium Test Kits for anyone to use, the chemicals are time-use dated. We suggest checking the printed expiration date on the foil packets before buying any of these kits, because any particular one may have been kept for some time on a store's shelf. If you happen to get outdated reagents, contact Aquarium Systems to see if they might replace them. They did this for us when we had a large quantity of expired ammonia test refills at one time.
