How do you prevent bacterial growth in your watering/feed reservoir?
I’m not a hydro guy. but I expect @Myfriendis410 can nail this one.

First: keep water temps below 70F. A product like Hydroguard added to the nutrient solution will also help. Keeping good cleaning practices is important.
Folks have tried to maintain temps using frozen water bottles, but this is not very effective. You will be changing them out hourly and spending a huge amount of time. Kind of defeats the idea of hydro.
How about more information and pictures? Lights, nutes, type of hydro (DWC, RDWC etc.).
I am growing in coco (not hydro) but I am setting up an auto watering system. The system features a reservoir that will hold the water/nutrients. The reservoir will probably need to be refilled weekly (it is a 7 gallon black bucket with aeration). So, is there something that I should treat the water with to prevent bacterial growth? I would prefer not to kill the beneficial microbes that exist in the growing medium.
No need to maintain temps (unless they’re out of hand) for gravity feed bases. I use Autopots with a 14 gallon rez outside the grow space and it has never caused problems. I do recommend agitating the liquid: I use an aquarium wavemaker.
You can still add Hydroguard to your rez if you think you need it.
Thank you
