GrowMax Maxquarium 000PPM RO Filter Unit 500 L/Day

Ultra Pure Water at 000PPM, Straight From the Tap

The GrowMax Maxquarium pairs reverse osmosis with a de-ionisation stage for water at a true 000PPM. It produces up to 500 litres per day and up to 20 litres per hour, and the 10" de-ionisation filter removes 100% of the mineral salts left in the RO water. That is a genuinely blank baseline for nutrient mixing, and water pure enough for aquariums, keeping algae minimal and pH balanced.

Key Benefits

• 000PPM EC from the combined RO and DI stages – nothing but what you add
• Up to 500 L/day at 20 L/h, with no waiting around for the tank
• Eliminates 100% of salts and heavy metals and removes up to 99% of chlorine
• Reduces up to 95% of mineral salts, heavy metals, chloramines, nitrates, nitrites, sediments, sand, oxides, herbicides, pesticides and volatile organic pollutants, plus sediment to 5 microns
• Helps stabilise pH and improves fertiliser performance
• Protects beneficial soil microorganisms that chlorinated water knocks back
• Doubles as an aquarium supply, making water quality, nitrates and alkalinity easier to manage

High Starting EC and Unstable pH

When the water going into your reservoir already carries dissolved salts you are feeding blind: EC readings mean less, pH drifts between feeds, and you get poor nutrient uptake and slow growth no amount of tweaking the chart fixes. Mixing from 000PPM water means the EC on your meter is your nutrients and nothing else, so a recipe that works keeps working.

How to Use

• Connect to a cold water supply and run the pure outlet into your reservoir
• Check your pressure – if the supply is weak, a booster pump brings production up to spec
• Change the 10" filter pack roughly every 4000L
• Change the 150 GPD high flow RO membrane when EC rises or production drops off
• Change the 10" de-ionisation filter on the same signal
• Mix nutrients after filtering, then set pH as usual
