API 5-in-1 and Tetra 6-in-1 strips supply 25 per pack; API Freshwater Master supplies 800 tests across five checks.
Quantity differs from coverage. Reef Master and HI772 do not cover ammonia.

Read the parameter names before counting them
Parameter counts range from 1 to 6. API Freshwater Master covers 5 parameters with ammonia among them. Tetra EasyStrips covers 6, but its parameter names include chlorine rather than ammonia. Parameter coverage and package descriptions identify the kits, without evaluating readings against water samples or a reference instrument. The larger count does not answer the same water-quality questions. Match the actual parameters and intended water type to the measurements you need.
Pick a sampling process you can follow consistently
API Master kits use liquid reagents; Seachem Ammonia Alert is an in-tank card; Hanna Marine Alkalinity Checker uses a checker format. These formats involve different sampling and reading steps, and their names do not demonstrate accuracy. Read reagent, timing and interpretation directions for the parameter you intend to measure.
Package yield is not a refill calendar
Maker package yields range from 25 to 800 water tests. API Freshwater Master supplies the 800 endpoint; Tetra EasyStrips and Hanna’s alkalinity checker each have a 25 value. Those counts do not imply equal use across parameters and cannot predict how soon you will need refills. Read what each maker counts and which reagents are included.
Before you buy
Can I use a freshwater kit in a reef tank?
Use the water type named on the kit. API sells separate Freshwater, Saltwater and Reef Master kits because they check different values; the Saltwater Master reads ammonia, nitrite, nitrate and pH.
Which kits test just one thing?
Five do: API’s Nitrate and Nitrite kits, Salifert’s Nitrate Profi-Test (60 tests), Seachem’s MultiTest Ammonia (75 tests) and Hanna’s alkalinity checker. A single-value kit often makes sense when one reading is the one you watch. Far more from liquid. API’s 5-in-1 and Tetra’s 6-in-1 strips come 25 to a pack; API’s Freshwater Master holds 800 tests over five checks. Strips give a quick all-in-one read. Reef keepers get API’s Reef Master (550 tests) or Hanna’s HI772, alkalinity only; neither tests ammonia.
Why do some ammonia products show nothing?
Their values had been copied from other products and were removed. API’s Ammonia Test Kit and strips, Jungle’s Quick Dip and Tetra’s EasyStrips Ammonia stay on the page, but they drop out as soon as you set a filter.
