SS diffuser stone and Oxygen

[Beau815]

So i decided that I need these items to aerate when i do my full boils... i looked on ebay and saw no SS stones... can i just pick em up at a pet store? Also I did see small liter sized oxygen tanks for like 15 bucks at hardware stores... How long do these last? I read 30 seconds per 5 gallons thats GREAT! Should last a while... Ill also need a special tube im guessing to connect... I couldnt find a thread that answered all these relating so specifically to a SS diffuser stone and Oxygen bottle with tubing... or how long they last... shed any light?

Got mine from Williams Brewing. Sainless wand, tubing, stone, and valve. I get several batches from one small tank. I pay about $6 for them at the local hardware store. I aerate for 30-45 seconds for 12 gallon batches.

Do you usually sanitize the wand in the boil or in starsan(or whatever)?
