Reverse osmosis and skimmers

The foundation of a stable aquarium is impeccable preparation water and efficient waste removal . Reverse osmosis systems guarantee ultra-pure water for your salt/bacterial strain mixes, while skimmers ensure continuous extraction of organic compounds before they turn into nitrates and phosphates.

• Prepare your water with our seawater aquarium reverse osmosis systems for stable parameters from the start.
• Optimize water quality and oxygenation with Arka skimmers , designed for fine foam, precise adjustment and simplified maintenance.
