The new SpectraPure® LiterMeter III is an automatic precision dosing system for the aquarium and horticulture industry. Three independent programs control one built-in pump and up to 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 pump is made out of 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 custom-designed by the premiere U.S. manufacturer of precision high reliability motors made to our specifications as a peristaltic drive motor. For example, many of the cars in NASCAR® use five or more motors of this design for cooling purposes; a major ink-jet printer manufacturer also uses them.
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 uncalibrated 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. Superior three-roller direct-motor drive eliminates noisy gears and improves flow accuracy and tubing life. It can be run dry without damage, and pumps either from a draw height of 12 feet or to a delivery height of 16 feet.
Three independent programs control the internal pump, as well as two optional external pumps. The SpectraPure® Remote Pump Module is a LiterMeter III pump mounted in a small plastic box. The SpectraPure® Top-Off Control Module is an optional level sensor that interrupts power to the LiterMeter III when a high water level is detected. The SpectraPure® Water Exchange Module combines a Remote Pump Module and an Top-Off Control module in one package, interrupting power only to that pump.

SpectraPure® LiterMeter 3 Remote Pump Module (LM3-RPM)

Another great Spectrapure product. Just plug it into the Litermeter III, calibrate the pump, set the flow rate and tell the Litermeter III to put the extra pump in run mode and you are all set.
My Litermeter III is about 4 years old, I did notice this new external pump is much quieter than the original pump in the Litermeter III base unit.

I have been running my remote pump for about a week now with no problems. In my system I have it drawing water from the basement (+- 8 feet) to a resevoir near the tank. Calibration was simple, although I would recommend recalibrating after a few days use. I would recommend this product for many applications. I plan on setting up a water exchange system using 2 pumps.

Great product so far
Great product so far... bought 2 at the same time I got the main unit and had all three pumps running within an hour... Seems just as efficient and quite as the main pump... Great product
