I’m thinking about tarps for the IBC tanks. The tanks are clear enough to get enough light to grow algae. I guess those tarps that are brown/silver and do silver side up for most of the year and brown side up for winter to help keep them from freezing. Tarps will be ugly but oh well. Better than green slime water clogging up the drip. Seems like after the green slime, comes little swimming things too.
I’ve been using it too fast for algae to grow but it won’t always be that way. Had a little once but it rinsed out easy and was only near the bottom. Don’t really want to add bleach/chlorine. Most anyone with city water and a garden is likely watering with chlorinated water at 1ppm or so and it doesn’t seem to hurt anything. Would prefer pure rain water though.
I keep hoping you find a job that earns enough to get a well! Or, next job is with someone who drills wells and you can get it done for less!
In any case, good luck!
