Reverse Osmosis

Reverse Osmosis Systems — Pure Water Starts Here

Every healthy reef starts with pure water. Our Reverse Osmosis and RO/DI systems strip out chlorine, chloramines, heavy metals, nitrates, phosphates, and silicates before they ever have a chance to fuel algae blooms or stress your corals — giving you a clean, stable foundation for saltwater mixing and top-off.

As an aquaculture-first coral farm, we run these same systems ourselves to grow healthy, pest-free coral at scale. We don't sell what we wouldn't run in our own systems.

Featuring IceCap RO/DI Systems
We've partnered with IceCap to bring you reliable, high-performance RO/DI systems built for hobbyists and commercial-scale coral farms alike. IceCap has built a reputation in the reef industry for dependable equipment — and their water purification line is no exception.

Why Water Purity Matters

• Eliminates phosphate and nitrate sources that fuel nuisance algae
• Removes chlorine/chloramine that stresses fish and invertebrates
• Produces consistent, 0 TDS water for accurate salt mixing
• Protects your investment in corals, fish, and equipment from contaminated tap or well water

Shop IceCap RO/DI Systems by Capacity

• 70 GPD — compact footprint, ideal for nano and small reef setups
• 100 GPD — the sweet spot for growing tanks and frequent water changes
• 150 GPD — built for larger displays and multi-tank systems
• 200 GPD — commercial-grade output for frag farms and high-volume operations

Booster Pumps
Maximize efficiency and output on your RO/DI system — especially important for low incoming water pressure or higher-capacity units. A booster pump keeps your membrane performing at its rated GPD instead of underperforming due to pressure loss.

Filter Packs & Replacement Cartridges
Keep your system producing clean, consistent water. Replace sediment, carbon, and DI resin stages on schedule to protect your membrane and maintain 0 TDS output.

The WWC Standard
We stock systems built for reliability and consistent output — not just entry-level units. Whether you're setting up your first nano reef or scaling a coral farm, IceCap has the right GPD system for your water demand.
