nothing.....I mean nothing hits my tank without being dipped........I dont care where it comes from....for the twenty bucks and 20 seconds it takes I find its worth it.....a good iodine based dip will work for most pests...."coral rx" is slightly more aggressive and will kill almost everything(save redbugs)....seachem either has already, or will have, a new coral dip that is said to also kill red bugs...do follow the instructions to the letter with the last two products.....one mistake with either amounts or dip time could prove to be
