OPTIONAL DILUTION INSTRUCTIONS IN HYDROPONIC SETTINGS: The following dilution chart is consistent with the other dilution instructions contained in this technical bulletin. It is tailored to the typical dilution ratios of 1:5, 1:10 and 1:200 necessary for hydroponic applications. Use this chart, or dilution instructions presented elsewhere, most compatible with available dilution devices.
NOTE: Verify concentration using Gard'nClean® Test Strips. For concentrations above 10 ppm, use Gard'nClean® Wide Range test strips; for concentrations of 10 ppm or less, use Gard'nClean® Low Range test strips.
1 Exceeds capacity of 55-gallon drum; activating the GC 30 in a 55-gallon drum and diluting with a 1:10 injection device will yield an application solution at a concentration of about 5.76 ppm— effective, but higher than necessary.
2 Exceeds capacity of 55-gallon drum; activating the GC 30 in a 55-gallon drum and diluting with a 1:200 injection device will yield an application solution at a concentration of about 0.27 ppm—effective, but higher than necessary.
To control and suppress bacteria [(Erwinia chyrsanthemi)], including algae (Phormidium boneri); [(Penicillium digitatum, Botrytis sp., Fusarium solani,] Pythium aphanidermatum, Pythium irregulare, Fusarium oxysporum f. sp. Basilicum (Fob)) on ornamentals, edibles in hydroponic gardens.
(Not For Use In California):
- Activate GC 30 according to “Directions for Use” on the package label.
- Prepare a 10.0 ppm solution of GC 30 OR prepare a 500 ppm solution of activated GC 30 and use a 1:50 dilution device or add one part 500 ppm solution to 49 parts water.
- Immerse or ornamentals, edibles. Ensure crops are visibly wet with solution for ten (10) minutes.
- Dispose of package and spent envelope according to instructions on package label.
AS A DIP, SPRAY, OR DRENCH AT A CONCENTRATION OF 5.0 PPM
- Activate GC 30 according to “Directions for Use” on the package label.

FOR CONTINUOUS TREATMENT TO SUPPRESS BACTERIA AND INHIBIT ALGAE, BIOSLIME, SLIME, AND BACTERIA AT A CONCENTRATION OF 3.0 PPM
- Activate GC 30 according to "Directions for Use" on product label.
- Using a dosing pump, add activated GC 30 to watering system until water reaches a concentration of 3.0 ppm (required concentration levels vary according to site-specific conditions—monitor the microbial content of the water and increase or decrease the addition rate of the activated solution as needed); [higher chlorine dioxide injection rates, such as 3.0 ppm can ensure chlorine dioxide residual of up to 0.8 ppm is sufficient to provide adequate treatment]. Residual disinfectant and disinfection byproducts must be monitored as required by the National Primary Drinking Water Regulations (40 CFR Part 141) and state drinking water standards.
- Dispose of package(s) and spent envelope(s) according to instructions on package label. Do not reuse.
NOTE: Use ultra-low-range Gard'nClean® Chlorine Dioxide Test Strips to verify concentration at downstream production points. Organic loads vary across water supplies, and will influence injection level necessary to ensure 3.0 ppm concentrations at emitter hoses, mist nozzles, and drip tubes.
FOR CONTINUOUS TREATMENT TO SUPPRESS BACTERIA AND INHIBIT ALGAE, BIOSLIME, SLIME, AND BACTERIA AT A CONCENTRATION OF 0.8 PPM
- Activate GC 30 according to "Directions for Use" on product label.
- Using a dosing pump, add activated GC 30 to watering system until water reaches a concentration of 0.8 ppm (required concentration levels vary according to site-specific conditions—monitor the microbial content of the water and increase or decrease the addition rate of the activated solution as needed); residual disinfectant and disinfection byproducts must be monitored as required by the National Primary Drinking Water Regulations (40 CFR Part 141) and state drinking water standards.
