how many moth balls can i put safely into a 16 gallon take and will they totally disolve or do i have to make them dissolve before hand

I think the most important thing here is , what kind of moth balls should I use ? then how manny per gallon ? Ok , make sure your moth balls say on the box "OLD FASHIONED" and NAPTHA . If the box says "Paradichlorobenzene" yes thats right para- di - chloro- benzene , DO NOT EVER USE these ! Its akin to a five pound bag of sugar after a while with blend grade (caseys) gasoline . Your not gonna gain that much . Seven to ten balls to a gallon was the number . Why don't you try a bottle of " ZERO TO SIXTY" available at your local Wal-Mart store for about five bucks .. I willl personally stand behind this stuff (IT WORKS DAMN GOOD). It has MMT , Oh alright ,here we go " Methyl-Cyclopentadienly-manganeese-tricarbonyl and other petroleum distillates ! (WASH HANDS AFTER EACH USE ) !! Don't let it sit if you spill it on painted surfaces !!! It works great for five bucks !! PBN
