I am all excited now because my boat is in the water and in a week or so I will start to go collecting. I want to get a new influx of bacteria in my tank and I need to go about a mile from my marina for that. The water under my boat, although teeming with life is not a good place to collect as that water is mostly sludge, gas, tar, fuel oil, anthrax, paint, sewage, some meat from Lady GaGa's dress, and a few high heels from the swim suit models they sometimes have there when there are new boats to show. I go there when they have those shows just for the research factor.
My tank depends on bacteria and that is one important aspect of why it has lasted so long with no problems and it also allows my fish to keep the immunity they were born with. If I have the disease problems many people have I would get out of this hobby and perhaps start a new hobby like guessing the phone numbers of Supermodels or seeing how long I can grow my toenails.
My tank runs with no disease problems as it has for decades and I realize it is because as many people tell me "I am lucky". I guess I am lucky as I have no varicose veins, acne, the heartbreak of psoriasis, gout, nose piercing, athletes foot or any number of other things many people have. My tank depends on bacteria, viruses and parasites to keep it immune.
I will go to that tide pool and grab a few handfuls of mud along with amphipods and anything else I can find and dump it all in my tank as I have been doing since Nixon was President. He didn't have a reef tank as far as I know but if he did he kept it at the Watergate hotel (google it)
