In summer i started testing my Aquaphonics system, that will be installed in greenhouse in future. I got several barrels nearly for free and I maked a siphon system. Than I bouth 12V pumps. Because I expected to have a source of electricity from solar panels.
I did set it up and start circulating water. I purchased 20 fishes and everything looked good.
And than problems started. My pump died. Luckily I had a backup pump installed. So I fishes were secure. I run to get a new pump and installed it. After several days new one died as well. This did repeat several times. After while I decided to go fro 220V pump and my problem disappeared.
In future green house I have to get really proper pups for 24V. My solar system is now 24V, but that is different story. And the pumps have to be really durable and high quality.
And Aquaphonics system has to be so setup, that when pumps stops pumping fishes will not die and flower will by flooded well.
Thanks good I did this experiment.
