Calculating water parameters using rain water?
Hi everybody, I'm getting ready to start filling my tank and stocking soon! But before I do that, I need to test the water in my area first. Right now, I'm just using a Brita filter to get rid of most heavy metals, leaving the container sit for 24 hours in front of a fan to (not only keep my room at above 0%humidity but also to) get rid of chlorine, and will neutralize with prime anything else. However, a friend of mine just tested her water, and she said that the GH and KH were so high that they went over her tests parameters...luckily, it's been raining a lot here, so I can collect some rain water to at least figure out what my parameters are before I try to get livestock. For reference, HC 'Cuba' is growing quite well at least DSM wise, as well as some unknown Rotala/Ammania species. But how do I go about figuring out pH and GH using rain water to reduce pH and GH to testable levels? I know that you can do this...but I can't for the life of me remember how to do so....
Oh, and additionally, can I add driftwood and carbon to the sitting water to bring the pH and GH even down harder while keeping the water clear? If so, how long should I let it sit?
So many fish to keep, not enough aquaria.
