The Ultra Reef UCS range of calcium reactor integrates and maintains the level of calcium and alkalinity within an aquarium. The reactor is filled with calcium-based media and continuously filled with aquarium water that flows out slowly. Using the CO2 provided by the connected vessel, it lowers the pH of the water that recirculate in its interior to the Point of dissolution of the medium which slowly consumes and release carbonate and calcium ions (and other elements) constantly in the Aquarium.

The experience gained in more than half a century in the field of fluid dynamics has made it possible for Ultra Reef to offer a product with the following characteristics:

An efficient and economic integration system

The calcium reactors are a simple and functional device for the maintenance of the values of calcium, magnesium and KH in marine reef aquariums. The lower perforated plate diffuses the flow of water, ensuring a constant and homogeneous recirculation in the chamber and in contained material. This solution reduces the risk of medium compaction and allows it to be exploited until exhaustion.

Modern design and smart pump positioning

The pump is placed on the bottom of the reactor to reduce the lateral ingots. This solution significantly reduces power consumption and the risk of dry operation by preventing accumulation of carbon dioxide bubbles in pump housing. Pump submerged position prevent its harmful overheating while the reactor chamber remain raised by the water of the sump, preventing the heat generated by the melting process heating the aquarium water.

Strong and durable structure

Most of the reactor is made with PVC components machined from solid and bolted together. The absence of small moving parts gives the structure an excellent solidity. The covers use a system of silicone gaskets O-ring and are tighten by titanium screws, while the rapid connection fittings with O-ring seal allow quick and safe installation of discharge and load hoses.

Integrated CO2 recovery system

The recirculation pipe is installed in the upper part of the conical cover and performs the function of recovering CO2. This solution significantly reduces the consumption of carbon dioxide and limits the emission of the same in the aquarium.

Complete of connection hoses

The reactor is supplied complete of water load hose, water drain hose with regulation valve, CO2 load hose, bubble counter and pH probe attack.

Easy and thorough maintenance

The product can be disassembled virtually in every single component. The generous thicknesses of the materials used ensure excellent resistance during all maintenance, while small component reduction facilitates cleaning and replacement of individual worn components.

Design, Quality and Performance

During the product development, from the very beginning the focus is set on what the aquarist really needs. The construction choices used by Ultra Reef always have a practical logic and often depart from a direct need, which could not be fully satisfied by products currently available on the market.

Made in Italy product

The company was founded in 1957 and since then has produced hydraulic equipment and flow devices of the highest quality without compromise. At Ultra Reef they work with care and passion, which has always characterized Italian companies. Their success is based on customer satisfaction through efficient processing and delivery of high quality products at competitive prices.

CNC machining of full blocks of PVC

Ultra Reef performs all of the internal development of their products in house, from design to production. The brand guarantees a deep and careful evaluation of the operation, both technically and aesthetically, thanks to the CNC machining of full blocks of PVC.

Research and development without reliance

Thanks to continuous research for innovations and new technologies to be used in manufacturing process Ultra Reef is always at the forefront in development of their products. Flexibility and speed of response to recent searches in the sector guarantee their products excellent performance.

Anticorrosion Titanium Screws

The screws according to DIN7985 are made of titanium G2 and are resistant to corrosion caused by sea water - even the smallest components are of the highest quality.

ISO 9001 Quality certification

The best quality can only be achieved if everyone involved in production is aware of their responsibility and production processes are continuously improved. The company is certified and complies with ISO 9001, the most widely used international standard for quality management systems.
