Do I need a reverse osmosis machine for rain water and hydroponics? - Page 2 - Indoor Grows - Hydro - International Cannagraphic Magazine Forums

If that is the only water you have to work with, I think I would pursue chemically treating the water in some kind of storage tank. Then work on filtering out the particulate matter and the chlorine (or what ever oxidizer you choose) after it is 'safe' to drink. 30 ppm isn't much, it would be nice to know what makes up that 30ppm, but it shouldn't cause too much havoc, so I don't know that I would pursue RO. I'm thinking hauling water may be a better option than trying to turn that water into potable water; which in my opinion is what you need to do. If I wouldn't be willing to drink it, I don't think I would want to put it into a hydro system. Bottom line, I think this is a bit more of a task than popping a filter on, or dumping a little bleach in; and not sure it is worth it. But that is something that you would need to decide.

That's good honest advice. I appreciate it. Thank you.

I've used well water, seasonal creek water, river water, City water, city water on ro, well water on ro, and currently rain water stored in a very large plastic tank.

I honestly don't believe it's your water that is the problem. If you fill a bottle of water and let it sit in your grow room, you will see what is growing in it. You can even add a drop of molasses to feed the bacteria and funji, that will speed up the process.

hey buddy! 30 ppm is nothing! i let my ro filters get dirtier than that before changing. even if it is organic contaminant of some kind there is just not enough of it to kill your plants unless there is a toxin of some kind involved.

by your description of a delayed response it could possibly be an algal bloom that uses up all the free o2 and then dies, releasing toxins. but you would be seeing algae in the water.

i didn't see a mention of ph? algal blooms can cause rapid ph changes.

"The water itself has a slight yellow tinge to it." typically plant matter decaying in water gives off tannin and has a yellow/orange tint to it.

what is your cistern ph?

what nutrients are you using?
