1“ Fertilizer Injector

I installed this on my lawn irrigation system and appears to be working fine. This product should have more specification information. The one inch adapter I bought needs water flow between 8 to 28 gallons per minute to work. The flow rate in the specifications is shown as cubic metters per hour and needs to be converted to gallons per minute for us americans. This also needs about a 5 psi pressure drop from inlet to outlet to work. The pressure drop is not stated in the description. I am a novice but i think if you have less water flow then buy a smaller size.$100 cheaper than the name brand model so worth a try imho.

This product worked very well for my hydroponic system

no leaks, very powerful. 5 gals in 5 - 10 mins.

Use this to help put oxygen in pond and help from freezing water over in winter. Working just great

works perfect for my fish tank,bery little water pressure ,lots of bubbles,love it

I hooked this up to a powerful water pump to make a air jet and to create a strong current for my koi to swim against plus adding oxygen
