Frequently Asked Questions
Which Chemilizer model should be used in my application?
Answer: For flow rates of 1 GPH to 12 GPM - use the HN55, for flow rates of 12 GPM to 2500 GPM the CP33 should be used
What chemicals can be used with the Chemilizer injector?
Answer: Fertilizers, algaecides, fungicides, insecticides, pH controllers, bio-stimulants, Wetting Agents, Disinfectants, Spraying and more. Chemilizer injectors are very resistant to attack from most solutions.

- For a cart installation click here...
- For a parallel series installation, for double the flow rate, click one... CP33 HN55
- For installation with Hammer Arrestors, click one... CP33 HN55
How do I determine how to mix my stock solution?
Answer: This can be done on our fertilizer calculator 
How do I determine what PPM or amount of chemical is being injected into my system?
Answer: This can be determined by using the PPM chart . The amount of chemical is determined by the flow meter which is calibrated from 1 OPH to 6 GPH.
Disclaimer: to accurately determine PPM of fertilizers an, EC meter is recommended to test the water supply 
How do I use the PPM chart with the CP33?
Answer: This is an easy 3-Step Process:
First: Determine the total GPM in your irrigation system:
- Multiply total number of emitters by the water flow rate rated for each emitter.
Second: Determine PPM desired for application.
- Start at the top LEFT box on PPM chart:
- Go to the RIGHT to the total GPM setting in your irrigation system, and go DOWN to desired PPM setting.
- Then follow the PPM setting all the way to the LEFT to the float setting. This is your meter setting, and this is set by adjusting inlet or outlet valve on bypass installation.
Third: Ex. While looking at the PPM chart:
- If your desired PPM is 100 and the total GPM in the irrigation system is 25, then the setting should be approx. 1.5.
Would I use the PPM chart with the HN55?
Answer: No, because the HN55 is a preset injector that delivers a specific PPM based on the ratio pump you choose.
- 2:100 = 20,000 PPM
- 1:100 = 10,000 PPM
- 2:128 = 15600 PPM
- 1:128 = 7800 PPM
- 1:250 = 3900 PPM
- 1:500 = 1950 PPM
How do I change the ratio on my HN55?
Answer: The chemical pump assembly is available in different ratios and can easily be removed and changed to a different ratio when desired.
Will the external or remote injection of the chemicals mix properly into my water system?
Answer: Yes, we have tested this and chemicals are thoroughly mixed by time they have traveled 18" into any irrigation line
Why is the Chemilizer unit recommended by so many fertilizer suppliers for fertigation
Answer: Chemilizer has had 25 years of experience in this application, and our injectors have features not duplicated by any competitor's product. Refer to our Fertigation page for additional information that explains why Chemilizer injectors are the best choice when applying liquid fertilizers.
