High-Output 4-Stage RO/DI System with Improved Waste Ratio
The IceCap 150 GPD RO/DI System is a four-stage water filtration unit designed for hobbyists who need higher daily output and want to reduce wastewater at the same time. At 150 gallons per day with a 1.5:1 waste-to-product ratio, it produces twice as much purified water per gallon of feed water as the 75 GPD and 100 GPD models, which operate at a 3:1 ratio. For hobbyists on metered water, in water-restricted areas, or who simply run through a lot of purified water, this ratio improvement has a meaningful real-world impact on water use and cost.
The 150 GPD uses the same Dow Filmtec BW60-1812-75 membrane as the 75 GPD, which provides 96 to 99% typical salt rejection. The improved waste ratio comes from the higher operating pressure requirement: 65 to 80 PSI optimal, compared to 50 to 80 PSI for the lower-output models. Hobbyists whose home supply pressure falls below 65 PSI will need a booster pump to achieve the rated output and waste ratio on this model.
The system is slightly taller than the 75 GPD and 100 GPD at 16" x 6.5" x 18", but the footprint width and depth are the same, so it fits in most of the same under-sink and utility room installations. All other features are identical to the lower-output models: auto shut-off valve, manual flush flow restrictor, glycerin-filled pressure gauge, and all installation fittings and tubing.
Key Features:
- 1.5:1 waste-to-product ratio produces significantly less wastewater per gallon than the 75 GPD or 100 GPD models.
- 150 GPD output for faster fill times on larger systems or more frequent water changes.
- Dow Filmtec BW60-1812-75 membrane provides 96 to 99% typical salt rejection.
- Refillable DI cartridge with color-changing resin for visual exhaustion monitoring.
- Auto shut-off valve and manual flush flow restrictor included.
- No power source required; runs on 65 to 80 PSI household water pressure.
- Standard 10" canisters and 1/4" push-connect fittings.
- Glycerin-filled pressure gauge included.
- Same footprint width and depth as 75 GPD and 100 GPD; 3" taller at 18" height.
Ideal For:
- Hobbyists on metered water or in drought-restricted areas where reducing wastewater is a priority.
- Larger reef and saltwater systems where 75 to 100 GPD output creates a bottleneck during water changes.
- Installations where the supply pressure is reliably 65 to 80 PSI without a booster pump.
- Hobbyists stepping up from a 75 GPD or 100 GPD who want both more output and less waste.
Pro Tips:
- Confirm your supply pressure reaches 65 PSI before purchasing. Unlike the 75 GPD and 100 GPD models, the 150 GPD requires a minimum of 65 PSI to achieve its rated output and 1.5:1 waste ratio. At lower pressures, both output and waste ratio will degrade toward the performance of the lower-output models. A booster pump resolves this if the supply pressure is marginal.
- The 1.5:1 waste ratio means for every 2 gallons of RO/DI water produced, approximately 3 gallons go to drain. At 150 GPD production, this adds up quickly. Routing the drain line to a garden, lawn, or utility use is a practical way to put the reject water to work rather than losing it entirely.
- Flush the membrane before first use. Run water to drain for 30 to 60 minutes before collecting product water to clear the membrane preservative.

Warranty
CoralVue, Inc. hereby guarantees this product to be free from defects in material and workmanship for a period of:
- 1 Year
Warranty is activated on the date of purchase.
This Standard Limited Warranty applies and is limited as follows:
- To the product only as long as it remains in the possession of the original purchaser.
- To the product that has not been subject to accident, misuse or abuse.
- To the product that has not been modified, altered, defaced, or had repairs made or attempted by other than CoralVue, Inc.
- That CoralVue be immediately notified in writing within ten (10) days of first knowledge of defect by owner or his agent.
- That CoralVue, Inc. shall be given first opportunity to make any repairs, replacements or corrections to the defective construction within a reasonable period of time.
- Under no circumstances shall CoralVue and/or the Manufacturer be liable by virtue of this warranty or otherwise for damage to any person or property whatsoever for any special, indirect, secondary or consequential damages of any nature however arising out of the use or inability to use because of the product defect.
Instructions:
- Check feed water pressure. Confirm your tap water line delivers 50-80 psi. Use the included glycerin-filled pressure gauge after installation to verify. If pressure is below 50 psi, a booster pump is required before the system for consistent output.
- Mount the bracket. Secure the filter bracket to a wall or cabinet in a location within reach of your feed water supply line and a drain for the waste line. Keep it out of freezing temperatures.
- Connect feed water. Use the included installation fittings to connect the system's inlet to your cold water supply line via ¼-inch push-connect tubing.
- Connect the waste line. Route the concentrate (waste) line to a drain using the provided fittings. Do not restrict or cap the waste line — this will damage the membrane.
- Connect the product line. Run the purified water output line to your storage container.
- Flush before use. Run the system for a minimum of 30 minutes before collecting water for use. Discard this initial flush volume to clear preservatives from the membrane and carbon fines from the block filter.
- Verify output TDS. Use a TDS meter on the DI output to confirm 0 ppm before using water in your system. Color-changing resin in the DI cartridge will begin shifting from blue/purple to yellow/amber as it exhausts.
Filter replacement intervals (general guidance — actual intervals depend on feed water quality):
- Stage 1 – Sediment filter: every 6-12 months
- Stage 2 – Carbon block: every 6-12 months
- Stage 3 – RO membrane: every 2-5 years
- Stage 4 – DI resin: when color change is visible, or when output TDS rises above 0 ppm
