Mad Farmer Oxygenator, 1 gal, Case of 4

Concentrated Peroxide Sterilization for Reservoirs and Equipment, 1 Gal

Stagnant reservoir water breeds odor-causing bacteria and biofilm on pumps, tubing, and fittings faster than most growers expect, and diluted general-purpose cleaners rarely keep pace between full reservoir changes. Mad Farmer Oxygenator is a 35% aqueous hydrogen peroxide solution dosed at a fraction of a drop per gallon to keep reservoir water sterile, eliminate odor, and clean equipment surfaces as it circulates.

At 1 gal, this size suits regular indoor and greenhouse growers dosing one to several reservoirs on a recurring schedule through a full growing cycle. Sold in cases of 4, it fits growers who reorder on a routine basis.

Key Features & Benefits

• 35% aqueous hydrogen peroxide — a concentrated oxidizer that sterilizes reservoir water and equipment surfaces as it breaks down.
• Odor elimination — keeps reservoir water and equipment from developing the sour smell of bacterial buildup.
• Sterilizes pumps, tubing, and fittings — circulates through the system to clean surfaces a manual scrub can't reach.
• Low dosing rate — used at roughly one drop per gallon, so a small volume treats a large reservoir.
• Breaks down to water and oxygen — leaves no persistent chemical residue in the reservoir once it reacts.

Who Should Use Mad Farmer Oxygenator

Growers who want to keep reservoir water and equipment sterile and odor-free between full changeouts, from home growers running a single reservoir to commercial operations maintaining multiple systems.

Frequently Asked Questions

What is Mad Farmer Oxygenator made of?

It's a 35% aqueous hydrogen peroxide solution, a concentrated oxidizer that sterilizes reservoir water and equipment surfaces as it breaks down.

Is this safe to handle at 35% concentration?

At 35%, hydrogen peroxide is far stronger than the 3% peroxide sold for household use and can burn skin and eyes on contact, so growers should wear gloves and eye protection when handling the concentrate and always dilute it per label directions before it reaches the reservoir.

How much should I dose per gallon?

Typical dosing is roughly one drop per gallon of reservoir water; because the concentrate is strong, growers should measure carefully rather than estimate, especially on larger reservoirs.

Does this replace mechanical aeration like an air pump?

No, it's a sterilizing and odor-control additive, not an aeration device; growers still rely on air pumps or air stones for the ongoing dissolved oxygen a root zone needs.

Can this be used to clean pumps and tubing, not just the reservoir?

Yes, because it circulates with reservoir water, it also helps sterilize pumps, tubing, and fittings that a manual wipe-down can't easily reach.
