Hydrologic MicRO Reverse Osmosis System - 75 GPD

Cleaner Source Water for Nutrient Mixes - 75 GPD Capacity

Tap water carries dissolved solids, chlorine compounds and minerals that make nutrient feeding harder to control. This reverse osmosis system filters water through a pre-filter and membrane, so you start from a more consistent baseline. Its capacity rating is 75 GPD.

At 75 GPD, this unit fits home gardeners, hobbyists and small indoor setups that need a steady supply of treated water without a large installation. Larger commercial rooms may want to compare higher-capacity systems.

Key Features & Benefits

• Compact reverse osmosis design — fits small grow spaces and is easy to place.
• Rated at 75 GPD — suits small to moderate daily water needs.
• Pre-filter and membrane stages — reduce sediment, chlorine and dissolved solids before water reaches your reservoir.
• Single unit — one complete system per order.

Who Should Use Hydrologic MicRO Reverse Osmosis System

Growers with hard or heavily treated tap water, hobbyists building a hydroponic system, and small-scale cultivators who want better control over nutrient strength.

Frequently Asked Questions

Q: What does reverse osmosis do for a grow?
A: It pushes water through a fine membrane that removes much of the dissolved material. That gives you a cleaner starting point for mixing nutrients and adjusting pH.

Q: What does GPD mean?
A: GPD stands for gallons per day. It is the rated amount of treated water the system can produce over 24 hours under suitable conditions.

Q: Is reverse osmosis water different from filtered water?
A: Basic carbon filters mainly reduce chlorine and odors. Reverse osmosis also reduces many dissolved solids, so the result is generally purer.

Q: Will it need maintenance?
A: Yes. Pre-filters and membranes wear over time, so plan to replace them on a regular schedule. Water quality and usage affect how often.

Q: Does it produce wastewater?
A: Reverse osmosis systems send a portion of incoming water to drain as part of the process. Plan a drain connection when you set one up.
