So when I opened and SLAMMED, I used the 10% (Walmart) but now that things are stable I'm considering going to the regular bleach @ 6% as it's a bit cheaper. However, seems that my local Walmart only has "no-splash" variety of their store bleach and something they call "Cleaning" bleach. Both are 6%. Which should I choose or should I bite the bullet and just keep buying the 10% stuff.
