Salifert Ammonia Test Kit

A TDS Meter measures the amount of Total Dissolved Solids (TDS) in a solution.

This measurement is used to determine the purity of the water produced by your RO unit and will give an indication of when your DI resin or membrane life is coming to an end. The inline version measures the TDS of the feed water before the RO Unit and the TDS of the pure water from the unit.

Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution which is then converted to a TDS reading.

TDS is directly related to quality of water i.e., the lower a TDS figure, the more pure the water. As an example, reverse osmosis purified water will have a TDS between 0 and 10, whereas tap water will vary between 20 and 300.

Temperature compensating refractometer with LED illuminated scale for salinity determination

This clever maintenance tool eliminates the need for multiple products by offering four unique interchangeable attachments in one space saving unit and is offered in 6”, 12”and 24” handle lengths to eliminate algae in the deepest aquariums without ever getting your hands wet. It’s the perfect tool to complement any size aquarium for quick and easy cleaning and husbandry.

The Nero pump you know and love, now in a smaller form factor. Aqua Illumination's Nero 3 creates an adjustable broad flow that is strong but gentle at the same time. Traditional propeller designs produce a hard stream that can irritate corals where the Nero 3's innovative propeller pushes water in a wide pattern that can move foods, detritus, or other free-floating particles around without blasting corals directly. Powerheads have many different uses around a reef tank, but the main goal is to produce enough flow to keep low-flow spots from forming in your tank and help elevate detritus to be sucked into the filtration. With BlueTooth LE technology you can set the pump up into different modes, or create a daily schedule to change the flow up throughout the day.

Aquaforest Hybrid Pro Salt combines chemically pure lab-made salt with natural sea salt flakes from the North Atlantic Ocean to deliver the best of both worlds for a more natural, probiotic-enriched reef aquarium.
