Crestedchik - do what? The spreadsheet thingy? Or were you referring to something else? As to H2O2 by the gallon - yes, you can find it in places dealing with swimming pool/spa supplies. Also, they may carry it at higher percentages than the standard 3% available at your local WalMart, grocery store or drug store.
