Aptus SYSTEM-CLEAN, 20 L

Maintain Planting Media, Irrigation Lines, and Growing Surfaces With a Single Acid Wash

Over time, any recirculating or irrigation system accumulates biofilm, mineral deposits, and organic residue — in the lines, the medium, and on cultivation surfaces. Addressing each of these with separate products adds cost and complexity; a single product that handles all three simplifies the maintenance routine without sacrificing effectiveness.

System-Clean uses hypochlorous acid — a weak acid that forms when chlorine dissolves in water — as its active ingredient. At the instructed dilution rates, it is safe to use in feed solutions and directly over planting media, making it usable as part of a regular feeding routine rather than only as an occasional system shutdown.

Two dosage modes cover the full maintenance spectrum: a low-dose regular maintenance protocol for ongoing use, and a higher-dose flush for end-of-cycle system cleans.

Key Features & Benefits

• Hypochlorous acid active ingredient — a weak acid that effectively cleans biofilm, organic residue, and mineral deposits without the harshness of strong acid cleaners.
• Safe for plants at instructed dilutions — can be applied directly over planting media and in feed solutions at the labeled rates without harming the crop.
• Cleans irrigation components — removes biofilm and mineral buildup from lines, emitters, and reservoir surfaces during regular maintenance and system flushes.
• Cleans planting media and substrate — penetrates the growing medium to break down accumulated organic matter between and within cycles.
• Cleans growing surfaces — effective on cultivation surfaces — trays, walls, benches, and containers — between cycles.
• 20 liter drum for commercial-scale operations — sized for facilities where system cleaning is a frequent, large-volume operation requiring reliable concentrate supply.

Who Should Use Aptus System-Clean

Commercial-scale growers running recirculating or irrigation-heavy systems who need an effective, plant-safe cleaner that handles media, lines, and surfaces in a single product — and want a 20 liter drum to keep the maintenance routine running without frequent restocking.

Dosage and Application Rates

Regular maintenance — add to every tank or reservoir: 2 ml per gallon (0.25 ml per liter). System and substrate clean — flush between cycles: 5 ml per gallon (0.5 ml per liter). Always follow label instructions for specific application methods and contact times.

Frequently Asked Questions

Is System-Clean safe to use directly over plants and planting media?

Yes, at the instructed dilution rates on the label. At 2 ml/gal for regular use or 5 ml/gal for a system flush, it is safe to apply over planting media and in feed solutions.

What is hypochlorous acid and how does it clean?

Hypochlorous acid is a weak acid that forms when chlorine dissolves in water. It's effective against biofilm, organic residue, and mineral deposits at low concentrations, and breaks down to benign byproducts at the dilutions used in System-Clean.

How often should I run a System-Clean flush?

Use at 2 ml/gal as part of every tank fill for ongoing maintenance. Use at 5 ml/gal for a full system and substrate flush between growing cycles.

Can System-Clean be used in recirculating hydroponic systems?

Yes — it's well-suited to recirculating systems where biofilm and mineral buildup in reservoir walls and irrigation lines are ongoing concerns. Apply at the regular maintenance rate with each reservoir fill.
