anti-bacterial soap and the tank

[Paintbug]

me and a fellow reefer were chatting today, and got on the subject of hand washing. i was explaining that i have a feeling that the soap i use in the household is causing my pods to slowly decrease in population. my thoughts are that the anti-bacteria soap residue is either killing off the food supply for the pods, and/or the pods directly. i do try to rinse all the soap off. most the time i spend 2-3 mins just rinsing. i started using the soap about 6 months ago. i used to have tons of amphipods especially. now i may see one or two a night if im lucky. my parameters are good, other than the nitrates are bouncing around 10ppm. i have been feeding phytoplankton for about 2 months straight to help feed them as well. so im kinda lost LOL. me and the fellow reefer thought this may be a good topic for discussion . any thoughts, or have any studies been performed on the subject or something similar?
