Red Sea Calcium Pro Testing Kit 75 Tests

Description

Red Sea Calcium Pro Testing Kit 75 Tests — Titration test reading calcium to 5 ppm for reef dosing

Dosing calcium without an accurate test is guessing, and a colour-chart kit cannot resolve the 10 ppm a reef consumes in a day. Red Sea Calcium Pro Testing Kit 75 Tests (SKU: RED250) is Red Sea’s advanced titration test for calcium in a reef aquarium, with what the maker calls an exceptionally high accuracy of 5 ppm. It is the test built for the Reef Care Program, giving the readings needed to dose Foundation A calcium and strontium and the Trace Colours supplements to measured uptake, and Red Sea sums up the whole approach in three words: it is all in the balance.

The kit contains Reagent A (25 mL), Reagent B (20 g) and 75 mL of Reagent C titrant, a titrator, a 5 mL syringe, a dosing spoon, a colour card and instructions, packed in a durable, chemical-resistant plastic case with analytical-grade glass vials. Titrant is added drop by drop until the colour changes, with the volume used read off the titrator as the calcium level. There are 75 tests in the box, enough for a year of weekly checks with spares for uptake tests, and a 75-test reagent refill means the case and titrator are bought once. The same test is included in the Reef Foundation Pro multi kit (RED257).

Usage & Application

When to Use

• Weekly calcium testing: Reefs on the Reef Care Program dosing Foundation A daily, where 5 ppm resolution shows the trend.
• Measuring uptake: The four-day test that sets a daily calcium dose.
• Checking new salt mixes: Confirming a bucket delivers its stated calcium level before the water goes in.
• Calcium reactor and doser tuning: Resolving changes of a few ppm that a colour-chart kit would miss.

How to Use

• Take the sample: Measure tank water into the glass vial with the 5 mL syringe.
• Add reagents: Reagent A, then a spoon of Reagent B, and swirl.
• Titrate: Add Reagent C from the titrator until the colour changes and read calcium from the scale.
• Record and dose: Log the result and adjust Foundation A to the recipe for the tank type.
