Fertilizing

Can I replace the dip tube in my 1 gallon EZ-Flo unit (IEZ1GUP)?
The ¾ gallon dip tube (IEZDIP34) is the replacement part for this unit but the universal dip tube (IEZDIP) will work with any EZ-Flo unit. To connect the dip tube to the cap you will need two dip tube adapters (IEZBCF).
Can I use pesticides, herbicides and other chemicals in my EZ-Flo injector system?
Yes, the system can be used to distribute any chemical or fertilizer. Read instructions carefully on the packages of any chemicals you plan to use. Often, products can be combined for one-step applications, but make sure they are compatible before mixing.
How much fertilizer should I put in my EZ-FLO injector tank?
Fill the tank with the recommended amount of concentrated fertilizer for your unit.
I am using a diluted organic fertilizer, but I can't tell if my injector is working. What can I do?
Movement of weak solutions may be hard to see in the tank's outflow tube but a dose of food coloring can be added to the tank. If there still is no fertilizer flowing, make sure any tubing valves are open or shut the system down and wait a few moments to restart it.
What is a fertilizer injector?
A fertilizer injector inserts nutrient solutions directly into irrigation water which is then fed directly to the plants.
Do I need to flush my system after I fertilize?
Always flush the system after fertilizing to properly maintain your irrigation system. This is especially important when using organic fertilizers.
Is it OK to use organic fertilizers in an injector with a drip system?
Yes, they can be used as long as the organic fertilizers are water soluble.
How do I choose which fertilizer injector to purchase?
The need for accuracy, simplicity of use, and the size and diversity of your system will be factors at which to look. Visit our fertilizer injectors page for further information.
What types of fertilizers are the best to use?
Grow More is the brand we sell, but any water soluble fertilizer is good to use with a fertilizer injector. Fish emulsion is NEVER recommended for use with drip systems.
I turn on my EZ-Flo injection system and no fertilizer seems to be coming out while water is coming in. What should I do?
If there is no fertilizer flowing after a few minutes of operation, shut off the system, wait a few moments and restart it. When starting, the system water flows into the tank until it is totally full and at the same pressure as the watering system. Fertilizer will begin to flow once this has happened. This can take a minute or more when the tank is refilling. Remember, the tank must be completely full of fluid before fertilizer starts to flow. Fertilizer with dark dye coloring will look darker flowing through the clear tubing than lighter colored fertilizers, even though they are feeding at the same rate. With low flow systems the fertilizer flowing through the tubing may have less color because the system automatically adjusts the fertilizer ratio to the water going through the system. Dry fertilizers can take longer to begin flowing than liquid fertilizers because they need to dissolve first. If you are using tubing valves, make sure they are in the "on" position. The green cap fittings are connected to the clear, downstream tube, while the blue cap fittings are connected to the black, upstream tubing.
If I fertilize every time I water will I over-fertilize with an EZ-Flo?
The highest setting on an EZ-Flo unit is a 100:1 ratio (1%). If you "fertigate" (fertilize with lower doses over longer periods of time instead of intermittent bursts of higher doses), you are unlikely to over fertilize.
Does the fertilizer get weaker as my EZ-Flo system operates?
The fertilizer is pulled from the bottom of the tank to maintain as consistent a feed rate as possible. But, since the fertilizer at the bottom of the tank is heavier than the water entering at the top, some dilution takes place.
How do I know when the tank of my EZ-Flo injector is ready to refill?
If the water in the clear tube still has color, it has fertilizer in it. However, you can refill the tank at any time.
Can I use dry fertilizers with a fertilizer injector?
Fertilizers should be completely dissolved in a solution (usually water) prior to injection.
Do I need back flow protection with my fertilizer injector?
Yes. All fertilizer injectors need adequate backflow prevention to protect the originating water supply. Check local codes for the proper back flow unit required in your region.
Can I use acids, caustics and abrasives with my fertilizer injector?
Acids, caustics, and abrasives should not be used with fertilizer injectors unless the injector, like the internal bypass MixRite (IMR2INBYP)), specifies it may be used for this purpose.
Do I need to pre-filter water for my injector?
Yes. Injectors require a 120 mesh filter at minimum. However, your emitters downstream (like Drip Tape) may require filtration up to 200 mesh.
Can I use fish emulsion in my fertilizer injector for a drip system?
No. Use only water-soluble fertilizer in your drip system. Fertilizers that are not water-soluble should be manually applied into wetted areas around emitters to avoid clogging your filter and emitters.
Is it necessary to flush an injector before and after use?
Yes. Use clear water for the first 1/3 of your cycle, fertilize for the second 1/3, and then switch back to clear water again for the final 1/3. This will prepare the soil to better accept the fertilizer and flush your system afterward.
Is more maintenance involved in using organic fertilizers with a fertilizer injector compared to using chemical fertilizers?
Yes, organic fertilizers used in an injector system take more attention and maintenance than chemical fertilizers. However, after any fertilizer application, a thorough flushing of the system with water for at least ten minutes should be done.
Can I apply organic teas with my fertilizer injector?
Yes. Though when applying organic teas let the tea settle and then filter with a fine cloth before using your injector.
Will organic fertilizers clog my Drip Tape?
Yes. Drip Tape has a narrow turbulent flow path and particles gather in this narrow, serpentine pathway much like fats build up in ones' circulatory system. If organic fertilizers are required it may be best to use thin walled, relatively inexpensive Drip Tape, which can be replaced regularly as clogging demands.
Which injector offers the most precise dosing?
The MixRite fertilizer injector is the most precise injector we carry. You decide the dosage rate you want, set your injector and it will inject fertilizer at that rate.
Which fertilizer injector would you recommend for a small garden?
The hose thread EZ-Flo automatic fertilizer system is the simplest low cost fertilizer injector to put into a small garden.
What types of fertilizers can I inject into my drip system?
Water-soluble fertilizers are most reliable in injection systems.
Do I install my Mazzei injector before or after my filter?
Generally place your filter after the MixRite, or any injector, particularly if you are using your system with Drip Tape. If your incoming water has large suspended particles, you may want to install a second filter prior to your injector to prevent plugging.
