Silver salts have been used in the past as an antibiotic. They kill a lot of bacteria. However unless you're dumping commercial quantities, (hundreds of gallons), not a gallon or two, and in your case probably a lot less, it shouldn't cause any problem in a sewage treatment plant. I know some people will tell you otherwise but you really can't cause that much harm.

Aside from my Digital Pentax, I am the recipient of some of my Dad's cameras. Included in the lot are a couple of Contaxes and a Leica M4. The Tessar 50 mm is supposedly good. The M4 has an assortment of lenses including what can either be described as a cannon or a do-it yourself SLR. Besides, my PX-20 is feeling left out. I will have to exercise it as well.

So....I am cosidering buying a bottle of T-Max, a bottle of rapid fixer and a few rolls of Tri-X to use once I have shot up the ancient 4 rolls of Plus-X I found. I have a couple of Yankee tanks and a single reel tank and what I think is a 3 reel tank. I will dump the ancient Microdol down a convenient drain, clean the bottles and be in business, I think. My scanner will scan 35mm negatives so I don't have to fuss with my enlarger.

I have a few questions for the group though. If I dump the Microdol into the town's septic system, will the Treatment Plant blow up or otherwise stop functioning. Is there a good way to clean out the plastic and glass (fixer) bottles or should I add to my collection? Have I lost what's left of my mind. Do I shoot the 15? year old Plus-X at 125, 64 32 speed? PS my LunaPro still works...I will need a source for the PX625a cells though.

All suggestions read......some taken!
