Collection: Red Sea Test Kits

Single kits and grouped sets

Red Sea's testing range splits two ways. Individual Pro kits cover one parameter each — calcium, alkalinity, magnesium, nitrate, iodine. Grouped sets pull related tests together: Reef Foundation Pro combines calcium, alkalinity and magnesium, Algae Control pairs nitrate with phosphate, and the Marine Care Program master kit spans a wider set. Which suits you depends on whether you test several parameters on one schedule or track a single number closely.

What the groupings are built around

• Reef Foundation covers the three elements consumed together by growing coral.
• Algae Control pairs the two nutrients usually looked at side by side.
• Trace Colors covers the trace side of the range.
• Single Pro kits replace whichever reagent runs out first.

Using them consistently

The value of any test kit is in the trend rather than a single number, so test at the same point in your routine and record results as you go. Reagents have a shelf life and titration kits depend on the reagent being fresh, so note when a kit was opened. Follow the procedure in the instructions exactly — Red Sea's titration kits in particular depend on adding reagent slowly and reading the endpoint carefully.
