For a full cleaning like the OP asked, i wouldnt suggest spraying something and whiping it out. If your going to do a full tank clean i feel itd be easier to rinse with bleach. Since your doing a full cleaning, your already taking everything out of the tank (substrate, plamts, etc) so pouring in a bleach solution and wiping it around then rinsing isnt that much more work.
and i apologize Grif, this is not a personal jab or me trying to be mean. i am just trying to state the facts. There are plus sides to using both but for me, i guess bleach is just the easiest and most effective way. I know from reading your posts, you are very smart and very informative. Im not trying to take a jab at ya :P
