Most hobbyists trust their test results without ever verifying the kit itself. The Multi-Reference Solution changes that by giving you a liquid with known, certified parameter values — tested against Fauna Marin's ICP-AES machine in their Seawater Research Laboratory — that you can run through any home test kit to see exactly how far off the kit reads from the true value.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eWhat makes this reference solution different from others is its saltwater matrix. The solution is formulated to match the ionic composition of real reef aquarium water rather than a freshwater or synthetic base, which means the results you get when testing it reflect real-world conditions rather than an idealized lab environment. A single 100ml bottle covers calcium, magnesium, potassium, alkalinity, salinity, strontium, nitrate, and phosphate — eight parameters in one solution.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eEvery batch is individually quality-controlled and tested. The certified values are printed directly on each bottle and vary by batch, so always use the values from your specific bottle rather than a published generic figure.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eOnce you have tested the reference solution with your kit and identified the difference between your kit's reading and the bottle's certified value, you can calculate a correction factor and apply it to all future readings from that kit.
