I visited a guy who just got out of the breeding business and he used it in high levels to, I quote "burn" all the organic matter off of all of his equipment and inside his tanks. It looked like it did a good job too because all his tanks looks brand spanking new. Definitely something to think about if you ever have a sponge filter or something that is extremely clogged with organic matter or just to clean out the inside of your tank instead of scrubbing it. He basically just filled his tanks to the brim and tossed PP right in and it did the rest.
Maybe jr could use it to kill that BBA?
