    AquaIllumination Nero 5 Powerhead

    Small, Powerful, and Smart!

    • Up to 3,000gph – A tankload of flow from a small in-tank footprint.
    • Painless Setup – Just connect and go, it’s as simple as that.
    • Smart Control – Easily create a schedule that fits your tank’s needs.
    • Multiple Pump Modes – Includes Random, Pulse, Constant and Schedule
    • Adjustable Flow Angle – Pump can be angled up to 15 degrees

     

    Aqua Illumination's Nero 5 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 5'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.

    ATK v2 - Automatic Top-Off Kit - Neptune Systems

    The ATK (Automatic Top-off Kit) is a simple, standalone, and complete solution for replacing water lost to evaporation.

    The new aquarium hobbyist has many challenges, but none is more annoying than the chore of adding water, every day, to make up for that lost to evaporation (a.k.a. topping off/up).  This alone usually makes the automatic top-off (ATO) device the first piece of automation equipment purchased.

    The ironic flip side of this decision is that a faulty ATO device is one of the leading reasons for catastrophic aquarium failure, or even worse, flooding of the house or business.

    Not all ATO devices are created equal. Sadly, many ATO on the market are made with cheap components, have very little protection against these catastrophes, and are just a nightmare to assemble and install correctly.

    An ATO does not have to be both a blessing and a curse!

    We designed our ATK – Automatic Top-Off Kit to not only be super-simple to install and use, but it is unique in the market as an ATO device with three layers of redundant monitoring and water-level control. The ATK does the work for you, while at the same time protecting your tank and your home.

    New Improvements for V2

    • New PMUP with improved longevity and reliability
    • Improved optical sensors

    The Hanna Marine Alkalinity (dKH) Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. This level of instrumentation also offers greater resolution and accuracy, but can cost hundreds of dollars. The Hanna Marine Alkalinity Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

    Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. Its concentration may extend from 0 to several hundred milligrams per liter,depending on its source and treatment. Calcium is necessary in plant and animal nutrition since it is an essential constituent of bones, shells and plant structures. Calcium in water as carbonate is one of the primary components of water hardness which can cause pipe or tube scaling.

    Hanna HI774 Ultra Low Range Phosphate Checker - Marine

    Our HI774 Ultra Low Range Phosphate Checker will be essentially the same specifications as the HI736 Ultra Low Range Phosphorus Checker however it will not require a conversion but read directly in parts per million phosphates compared to parts per billion phosphorus.

    The HI774 Ultra Low Range Phosphate Checker HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems including reef tanks. Phosphate is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results in a few easy steps.

    Innovative Marine HydroFill Ti- ATO Controller

    Automate freshwater replenishment, and say farewell to heavy lifting, unstable water parameters, and the need to frequently watch your water line.

    Topping off evaporated water for our aquariums is a tedious but essential task that every hobbyist encounters to maintain stable specific gravity & salinity levels.

    The HydroFill Ti ATO Controller takes advantage of your water's conductive properties to complete a low voltage circuit and cause a control relay to actuate and replenish water as it evaporates. This departure from outdated float sensors, offers the latest automation in electronic sensing for precise accuracy, repeatability, and no-moving part reliability.

    Customize your own "High and Low" set points to prevent constant On/Off cycling prone to single sensor design.

    Sensors utilize rare earth neodymium magnets for stationary placement and simple out of the box installation.  Small form factor makes it the ideal choice for nano to full size aquariums. Two Titanium electrodes are housed in each sensor for redundancy & consistent long-term performance in harsh marine environments.
