In a marine aquarium strontium plays an important role in accelerating the growth of coral and calcareous algae and natural sea water contains approx. 7 - 9 mg/L strontium.
Strontium is very difficult to test for, but if there is found to be a depletion of calcium in the aquarium then strontium levels are likely to be very low as well. It is advisable to maintain a strontium concentration of between 5 and 20 mg/L.
Salifert was the first to introduce a strontium test kit and this test measures both ionically free and moderately complex strontium in increments of 5 mg/L.
Sufficient for up to 25 tests.
Marine use only.
All living organisms, even plants, require oxygen to survive and thrive.
A low oxygen concentration will cause the aquariums inhabitants to slowly suffocate making them increasingly likely to become ill.
Oxygen is also required by an aquariums biological filtration to convert toxic ammonia and nitrite to nitrate.
The Tetra Test enables you to easily measure oxygen levels in your aquarium to ensure that you are providing suitable conditions.
An easy guide and comparison chart is included.
Each test kits provides around 30 tests.
Innovative Marine HydroFill – 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 ATO Controller System 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 This departure from outdated float sensors, offers the latest automation in electronic sensing for precise accuracy, repeatability, and no-moving part reliability.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 chemically inert graphite electrodes are housed in each sensor for redundancy & consistent long-term performance in harsh marine environments.
Innovative Marine HydroFill –Pump
Pair your auto top off with the industry's first low voltage air lift pump specifically designed for ATO controllers. The HydroFill ATO Pump System eliminates the guess work, and comes complete with a lift pump, return pipe and acrylic mounting bracket, 10 feet of silicone tubing, 3 hose clamps, and an optional hanging mount.
Engineered for high performance, this external positive displacement diaphragm pump, outputs up to 15 gallons per hour and max 5 feet of head. This self-priming pump is equipped with a built-in check valve to safeguard against back siphoning.
The HydroFill diaphragm pump is the smart alternative when compared to submersible pumps, diaphragm pumps offer the benefit of safely running dry and are thermally protected against heat build-up.
Versatile design offers 3 options for pump placement: hang-on, cabinet mount, or simply place on noise dampening rubber feet.
