Pond Boss Forums Thread Like Summary - Using a venturi to add dye and chemicals

Hello, I'm a newbie here. I have a 1 acre pond in my back yard and have recently purchased an aerator for it. It has 3 diffusers and a Gast 87R compressor. Every year, I need to spend money to put chemicals in to keep the algae away. This past summer I was using a yard sprayer mounted to the front of my Coleman Crawdad to distribute it. It worked, but was time consuming to get the sprayer, battery, trolling motor, etc in the boat. To help speed the treatment process up, I was thinking of using a venturi between the compressor and the diffusers to treat the pond. Has anyone tried this or am I destined to continue to use the boat to treat the pond.

Yes it would, but it still wouldn't help. When you apply the algaecide you are supposed to use a strong stream to break up the mats so the algae is exposed to the algaecide. If left in mats, the outer pieces of the mat are exposed, but it has a hard time penetrating the mats because water doesn't flow easily through the mats to carry the algaecide with it.

You can do an experiment by just taking the boat out in the pond and dumping the algaecide in the plume. BUT you'd have to trickle it in to get the same effect.


I still applaud the out of the box thinking, but I don't think it will work as well as you are expecting. Only one way to know for sure is to try it, at the very worst you will either stall out the compressor or plug the diffuser. Both are just mechanical things that can be fixed or repaired.

You will have to meter the algaecide in somehow so you don't overdose the area. Some fish are more sensitive to copper than others and if you see some dead fish, after doing it then that is what I'd attribute the deaths to.
