The Deltec Km500s is the compact and ultra-efficient solution to bring lime water to your Aquarium. This hydroxide reactor (RAH) is the ideal ally of reef bins to maintain stable alkalinity and crystalline water.
The Calcium reactor (RAH) Deltec Km500s is high precision technical equipment designed for marine aquariums. Although often called calcium reactor, its first function is the production of Kalkwasser (lime water), essential to counter pH variations and support the growth of small consumer corals.
In one Aquarium Reef, the pH tends to fall during maintenance phases or during the night. The Deltec Km500s allows to inject calcium hydroxide in a controlled way. This method presents three major benefits:
| Feature | Detail |
|---|---|
| Mark | Deltec |
| Product name | KM500S Hydroxide Reactor |
| Manufacturer reference | 87002000 |
| Water flow | 10 l / h |
| Reactor type | RAH (Hydroxide Reactor) |
| Compatibility | Seawater water aquarium / reef |
The Recifart Tip: The Deltec KM500S is particularly effective when connected to your osmole system. Osmotic water crosses the reactor before entering the tray, ensuring a regular and secure intake.
The Deltec KM800, also called Rah, is designed to maintain the calcium rate in low-consumer reef aquariums. It plays a crucial role in the pH of the water and helps precipitate phosphates (PO4) for healthier water.
The calcium reactor Deltec KM800 is designed for a passage rate of about 30 liters per hour.
Unlike limestone reactor (RAC) that can acidify the water, the RAH as the KM800 makes it possible to reassemble and stabilize the pH, which is ideal for aquariums tend to have a low pH, while naturally eliminating some of the phosphates.
Yes, with its reference 87002000 and the quality of manufacture Deltec, this reactor is a standard of reliability. It usually connects to a reserve of osmosis water coupled to an osmole system to compensate for evaporation.
