BarleyMAX+ is a concentrated liquid barley extract designed to support clear, balanced koi pond and water garden conditions through natural plant-based processes — without the mess, debris, and inconsistency of traditional barley straw bales.

Made in the USA under controlled conditions, BarleyMAX+ captures the beneficial compounds of 100% organic barley in a ready-to-use liquid that disperses evenly on contact with water. The fast-dissolving formula is ideal for ponds with active water flow, filtration systems, and bottom drains, ensuring the beneficial compounds reach every area of the pond.

When used as part of a routine maintenance program, BarleyMAX+ helps manage the excess nutrients and organic residue that contribute to cloudy water and unbalanced pond conditions — naturally, over time. It works in harmony with your existing filtration and biological systems rather than disrupting them.

Unlike bulky barley straw that can decompose unevenly, introduce debris, and require physical removal, BarleyMAX+ delivers consistent, measurable application with zero mess and no residue. Simply pour and apply — no soaking, no nets, no mess.

Safe for all aquatic life, wildlife, plants, and domestic animals when used as directed. Suitable for year-round pond maintenance and compatible with most pond care programs.

How to Use

Calculate your pond volume in gallons. Use the pond size calculation guide on the packaging or product page.
Shake the bottle well before use to ensure even distribution of the concentrated extract.
Measure the correct dose based on your pond volume using the application rate chart.
Apply BarleyMAX+ to areas of highest water flow — near waterfalls, pump returns, or surface agitation points — for best distribution.
For routine maintenance: apply every 2 weeks at the standard dosing rate.
If pond water is turbid or cloudy: apply a double dose weekly until clarity improves, then resume biweekly maintenance dosing.
For best results, use consistently as part of a regular pond maintenance program year-round.
Safe for use in ponds with fish, plants, birds, and domestic animals when used as directed.
