IceCap 200 GPD Reverse Osmosis RO/DI Water Filtration System

Description

IceCap 200 GPD RO/DI System — Maximum Output, Minimum Waste

The highest-capacity RO/DI system in the IceCap line — built for reef keepers who refuse to compromise on water quality, even at scale.

If you're running a large display, a frag rack, or multiple tanks, waiting on water is the enemy. The IceCap 200 GPD System pumps out up to 200 gallons of pure, 0 TDS water per day — nearly double the output of entry-level systems — so your next water change, top-off, or coral dip is never held up by your RO system.

And it does it efficiently. At a 1.5:1 waste-to-product ratio, this system wastes significantly less water than the 75 and 100 GPD models (3:1 ratio) — meaning you get more purified water per gallon that goes down the drain. For anyone on well water, metered city water, or in a drought-restricted area, that efficiency pays for itself.

Why Reefers Choose the IceCap 200 GPD

• 200 GPD output — the fastest fill times and largest water change capacity in the IceCap line

• 1.5:1 waste ratio — dramatically more water-efficient than lower-output models

• Dow Filmtec TW30-1812-100HP membrane — 96–98% salt rejection at 65 PSI, commercial-grade filtration

• Color-changing DI resin — see exactly when it's time to refill, no guesswork

• Auto shut-off valve — stops water flow automatically once storage is full, no wasted water or flooded floors

• No electricity required — runs entirely on household water pressure (65–80 PSI)

• Same compact footprint as the 150 GPD — 16" x 6.5" x 18", so more output doesn't mean more space

Built For

• Large reef systems and frag farms where daily top-off can't wait

• Multi-tank setups and fish rooms where output is the bottleneck

• Hobbyists on metered or drought-restricted water who still want maximum production

• Anyone with 65–80 PSI supply (or already running a booster pump) ready to maximize it

What's Included

Auto shut-off valve, manual flush flow restrictor, glycerin-filled pressure gauge, refillable DI cartridge, and all installation fittings and tubing — everything you need to get up and running.

Specs at a Glance

Same footprint as our 150 GPD, but with a higher-capacity membrane delivering 33% more daily output — if you're already considering the 150, the 200 is worth a second look before you buy.

Standard 10" canisters and 1/4" push-connect fittings mean replacement filters are always easy to find — no proprietary parts, no supply headaches down the line.

Compare IceCap RO/DI Systems by GPD

Not sure which size is right for you? As a rule of thumb: match your GPD to roughly 3–5x your weekly water change volume so your system keeps up without running constantly. Low incoming pressure? Every model pairs with the IceCap Booster Pump Kit below to hit peak output.
