ATO Automatic Top Off System Water Level Controller by JBJ : Tired of lifting heavy buckets to refill sumps or tanks due to evaporation?
There is finally a professional grade product that automates refilling evaporated water. The All-New A.T.O. (Automatic Top Off) device is the most advanced water level controller system on the market. Lifting heavy buckets and spilling water is now a thing of the past. Maintaining stable salinity and specific gravity are no longer a problem since the A.T.O. will refill as soon as the water level drops.
The A.T.O. will keep all salt levels at consistent parameters, ensuring an optimal environment for your tank inhabitants.
Advanced Features:
Float Sensors
The A.T.O. is equipped with (2) float sensors that activate within seconds when your water level drops and automatically refills your sump or tank until it reaches your desired set point. Each float sensor has been designed with an exterior guard preventing snails & hermit crabs from attaching to the sensors.
Electronic Controller Module
Our state-of-the-art electronic controller allows for (2) modes of operation with a total of (3) different set up scenarios, allowing you more choices for installation for your unique set up. Our compact controller also incorporates a visible LED panel + our innovative Audible Signal alerts when in operation mode.

AquaMedic Reefdoser Aquarium Dosing Pumps : The Reefdoser Aquarium Dosing Pump can independently control up to 4 dosing pumps. The interval controller allows for adjustment of the duration of the on/off cycle for each pump over a broad time span -from seconds to days. The Reefdoser can automate many tasks in an aquarium.

SP-3000 Dosing Pumps by AquaMedic : The SP 3000 dosing pump is an economic peristaltic pump for pumping small volumes of water. It is used with all bypass filters like the Nitrate reductor and Calcium reactor, but also to top up evaporated water combined with Kalkwasser reactor.

Niveaumat Auto Top-off Pump by AquaMedic : The Aqua Medic Aquaniveau top-off systemis an excellent solution, providing two low-voltage float sensors. One senses the level within the filter reservoir to turn on a top-off pump when the level there drops and another to shut off the top-off pump when the water level in the R/O reservoir gets too low, to prevent it from running dry.

The new LiterMeter III is an automatic precision dosing pump for the aquarium and horticulture industry. Three independent programs control one built-in pump and one or two external pumps. Perform 2-way water changes, in addition to eliminating the manual drudgery of dosing Kalkwasser, trace elements, or topping off evaporated water. Quiet operation, auto-calibration, and virtually maintenance-free.

The new aquarium dosing pump is crafted from precision-machined aluminum fabricated to exacting aerospace tolerances. For example, such critical tolerances as the rollers are machined to +/-0.0005". The outer surface is polished to a mirror finish. Internal surfaces are held to a 63 micro inch finish and hard anodized to provide a durable and low-friction raceway. The pump's planetary direct drive is at an 11:1 ratio, thus providing enough torque to generate over 40 pounds of pressure. This incredible lift enables the LiterMeter III to pump over 60 feet above itself at a flow rate of over 250 ml/min. It can also draw up from 25 feet below. The motor in the LiterMeter III is made by a manufacturer of precision high reliability motors made to our specifications as a peristaltic drive motor. The pump is so reliable we now offer a five year limited warranty.

Calcium maintenance and alkalinity control are essential for a healthy reef tank. SpectraPure's LiterMeter III eliminates the manual drudgery of dosing Kalkwasser, trace elements, or topping off evaporated water. Kalkwasser replenishment, to be most effective, should be added to your aquarium slowly and consistently to avoid precipitation of calcium carbonate. The LiterMeter III automatically and reliably performs this task for you.

The LiterMeter III offers features found only on expensive laboratory pumps. Built-in calibration features eliminate the guesswork of un calibrated competitive units. Unlike noisy industrial metering pumps sold to the aquarium trades, SpectraPure's LiterMeter III was specially designed for critical aquarium dosing and is so quiet you can use it in your living room. Improved three-roller direct-motor drive eliminates noisy gears and improves flow accuracy and tubing life. It can be run dry without damage. Three independent programs control the internal pump, as well as two optional external pumps. The LM3-RPM is a LiterMeter III pump mounted in a small plastic box. The LM3-TCM is an optional level sensor that interrupts power to the LiterMeter III when a high water level is detected. The LM3-WXM combines an LM3-RPM and an LM3-TCM in one package, interrupting power only to that pump. See the Operations Manual for application examples.

 

Aquaniveau Two Switch Dosing System by AquaMedic : A common mistake in the aquarium hobby is to run the output from an R/O filter directly to a mechanical float switch on the aquarium filter to compensate for evaporation. In this application the R/O produces very poor quality water because it is operated only in short bursts. An R/O filter produces its best water quality when run for an extended period of time. Therefore the ideal top-off system begins with a reservoir that is filled periodically by an extended run of the R/O filter. Water is then pumped, via a peristaltic dosing pump such as the Aqua Medic SP3000, from the R/O reservoir into the aquarium filter “on-demand” as water evaporates.
Obviously this type of top-off system requires a reliable level sensing system within the aquarium filter and a switching controller to operate the top-off pump to maintain the water level.
The Aqua Medic Aquaniveau is an excellent solution, providing two low-voltage float sensors.
One senses the level within the filter reservoir to turn on a top-off pump when the level there drops and another to shut off the top-off pump when the water level in the R/O reservoir gets too low, to prevent it from running dry. For larger systems the peristaltic pump can be substituted for a higher flow rate pump to better suit the inherently greater rate of evaporation.
In a second mode the Aquaniveau can be connected with an M-Ventil solenoid valve to control the R/O filter with a minimum and maximum reservoir level set by the pair of float switches.

Level Loc Top Off system by GAP Products : Fits most any aquarium or other type sump.
The water level is maintained by a polypropylene float with stainless steel hardware. The float has an adjustable arm for fine-tuning water height and can be swiveled nearly 180 degrees to the desired orientation.
The float is mounted on a riser arm that slides up and down allowing you to position the float at the desired height in the sump. The riser is secured with a nylon bolt.
A float switch and solenoid valve provide safety backup in the event the float valves fails or becomes obstructed by a pesky snail or power cord
The solenoid is 12V 5W for mininum power consumption and safe operation near water. As an added safety backup, the solenoid can be plugged into a timer (see our accessories) so that the water is only flowing for short intervals each day. This also allows your RO/DI unit to run less frequently and produce more water when it is running.
The bracket is built of rigid PVC for durability. The bracket is secured to the sump by two 1.5" nylon bolts on the outside and a large 1 7/8" suction cup on the inside.
Optional Timer:
Pre-programmed electronic timer that is set to come on 4 times per day. You can change the programming to whatever you prefer. The timer adds another layer of safety to the ATO and allows an RO/DI unit to run only 4 times per day which allows it to produce more water at one time.
