Magnesium Hardness Checker HC The hardness or hydrometric titer (TH) of water essentially corresponds to the presence of calcium and magnesium salts. It is directly linked to the geological nature of the terrain crossed. A calcareous soil will give hard water while a granite soil will produce rather soft water. The total hardness represents the sum of the calcium and...

Marinepure PLATE 20x20x2.5cm Designed for Ammonia and Nitrite Removal under high flow. Deep pore structure will allow development of low oxygen zones, which will help with control of nitrates. Perfect for the creative hobbyist as it can be easily shaped. Use in sumps, between baffles, shape to fit in tight/custom places.

Marinepure BLOCK 20x20x8cm Ammonia, Nitrite & Nitrate Removal Primarily designed to provide deep anaerobic zones for de-nitrification in passive or low flow systems. Live rock substitute Use in Aquarium sumps

Fresh water alkalinity photometer This measurement is important to define the corrosive characteristics of water, due mainly to hydroxide, carbonate and bicarbonate ions, and to anions which cause hydrolysis such as phosphates, silicates, borates, and the salts of some organic acids. Measuring alkalinity is essential when monitoring soil, drinking water...
