A sufficient supply of magnesium is as essential for the growth and well being of reef building coralline algae as calcium. It is one of the major constituents of seawater and is directly invo...

Magnesium and calcium concentrations and the ratio between these two elements are constantly changing in marine aquariums due to assimilation into the skeletons of corals and coralline a...

These hydrometers never need calibration. Indispensable for scientists and the committed hobbyist. The higher price wil...

The carbonate hardness or alkalinity corresponds to the buffer capacity of the aquarium water and therefore determines the stability of the pH-value in the water. With thes...

Nitrite (NO2-) is the intermediate stage of the aerobic nitrification and is highly toxic for fish and invertebrates. A too high concentration of nitr...

Phosphates are an important food component of all plants and absolutely necessary for the metabolism of every living cell. If the plants do not take up enough phosphate, th...

Tropic Marin PRO-CORAL CURE
In many aquariums, parasites and microbial diseases can appear on new corals especially Acropora corals that are weakened and stressed by transport. Due to the lack of natural enemies, these parasites and diseases propagate and spread quickly ...

Natural phytoplankton is an important supplier of energy and nutrients for leather corals and soft corals, shell-fish, and other fine particle filter feeders. PRO-CORAL PHYTON is a well-balanced plankton replacement suitable for all fine particle filter feeders in seawater aquaria. A premi...

Natural zooplankton is an important source of energy and nutrients for stony corals and other plankton filter feeders. PRO-CORAL ZOOTON is a well-balanced plankton replacement for stony corals, specifically, small-polyped stony corals and other plankton filter feeders in a saltwater aquari...
