Snappy has high levels of toxins in his tap water, so the original idea (though I'm not sure why he didn't put in the OP?) WAS
to have floating plants or stem plants floating in the water in order to attempt to remove the impurities that would be found in the tap OR rainwater, or both, as will probably end up being the case, as the bucket will be outside.
So I think this thread was to figure out what issues might arise from using the rain water that can and will get into the bucket along with the tap water. . .
Snapz, I'm confused as to what the questions on this topic are now. . .
If you've decided that rainwater is not going to be pure enough to risk putting in your tank, we're back at square one, and I REALLY
wish you had a basement to keep the thing indoors and use a light. Perhaps you could keep it in an area - like under the shade of a porch - where it will still get enough lighting to keep the plants healthy, but be protected from much rainwater getting in? My bucket is on my back porch, and the plants thrive, though it is in the shade most of the day.
Using a fine mesh screen will keep the buggies out and let enough light in, but won't do anything for any impurities that the plants can't take care of that might be present in the rain . . . Have you looked into trying to find any local environmental groups? I don't know about there, but around here there ARE
people who actually test the rainwater regularly for toxins etc., and keep reports on the health of the local ecosystem. . . something maybe that you could look into? Oftentimes in my area, these groups can be found through the water supply company (they are often hired by the government) and/or through local colleges.
More research is needed for sure, but I'm STILL
really excited about this experiment! So glad you're going to try it. I'd have done it myself, but I'm lucky enough to have nearly perfect water in my tap. Too bad everyone can't be so lucky!
