Red Sea Kh/alkalinity Pro Testing Kit 75 Tests

Description

Red Sea KH/Alkalinity Pro Testing Kit 75 Tests — Titration test resolving alkalinity to 0.14 dKH

Alkalinity swings are the fastest way to stress stony corals, and the only defence is a test that can see a tenth of a degree. Red Sea Kh/alkalinity Pro Testing Kit 75 Tests (SKU: RED251) is Red Sea’s advanced titration test for KH, the carbonate and buffer alkalinity of reef water, with an accuracy the maker puts at 0.05 meq/L, or 0.14 dKH. It is designed to enable accurate dosing of Foundation B, Red Sea’s buffer supplement, and it is the alkalinity test the Reef Care Program is built around, since alkalinity is the foundation element that moves most from day to day.

In the case are 68 mL of titrant, a 10 mL syringe, a titrator, colour card and instructions, analytical-grade glass vials in a chemical-resistant plastic box, and a 100 mL sample of the Foundation B buffer supplement, so a low reading can be corrected the same day. Titration reads the volume of reagent used to change the sample’s colour, which is how it resolves 0.14 dKH where comparator kits manage half a degree. The box gives 75 tests, and a 75-test refill with syringe and updated chart keeps it going without a new case. The same test appears in the Reef Foundation Pro multi kit (RED257) with calcium and magnesium.

Usage & Application

When to Use

• Daily or weekly alkalinity checks: Reefs dosing Foundation B or running a calcium reactor, where a 0.3 dKH drift matters.
• Setting the daily dose: The four-day uptake test that fixes how much buffer a tank uses each day.
• Total alkalinity, not carbonates: Red Sea warns against carbonate-only kits; this reads total alkalinity.
• New salt and cycling checks: Verifying a fresh mix, or holding 8.4 dKH through the Reef Mature program.

How to Use

• Sample: Fill the glass vial from the tank using the 10 mL syringe supplied.
• Titrate: Add titrant from the titrator a drop at a time until the colour changes.
• Read: The titrator scale gives alkalinity in meq/L and dKH directly.
• Correct: Dose Foundation B to the recipe for the tank, no more than 1.4 dKH in a day, and retest.
