Seachem Alerts Combo Pack 1 Year

• Seachem sensor technology.
• Includes Ammonia Alert and pH Alert.
• Continuously monitors ammonia and freshwater pH.
• No chemicals or test procedures are required.
• One year supply.

How to Use

Place both cards where you can see them, anywhere in the aquarium or the filter. There is nothing to mix and no test procedure — the sensors change colour continuously and you read them against the printed chart.

Ammonia Alert: yellow is safe (below 0.02 mg/L), green is alert (0.05 mg/L), blue is alarm through toxic (0.2–0.5 mg/L and above). It reads free ammonia, the fraction that actually harms fish, not total ammonia. Allow a few days to settle in; after that it responds to a rise in about 15 minutes.

pH Alert: yellow through orange to red across pH 5.4 to 8.0. Allow about 30 minutes initially, then around ten. Read it in natural daylight.

Do not touch the sensor faces — skin oils damage them. Clean algae off with something clean and soft, never bleach, soap, detergent or anything hard.

Tests per Kit

These are continuous monitors rather than a set number of tests: they are read as often as you like for as long as the sensor lasts.

The Ammonia Alert sensor lasts about a year in service before it needs replacing. Both cards measure 1.5 × 2.5 in.

pH Alert is for fresh water only. Ammonia Alert works in fresh and salt water, but is not recommended in acidic water, where almost all ammonia is in the harmless ionised form and the reading tells you little.

What’s in the Box

One Ammonia Alert card and one pH Alert card, each with its printed colour chart.
