Several years ago at the Oregon Gathering a couple had a huge mess going on in their black water tank. Wouldn't clear when dumped... had to disconnect a bunch of pipe, etc. Rubber gloves to the arm pits! They had used the Geo method for several years. Obviously that homemade concoction didn't work well for them. I hope it works for you.
Donna , I don't dump my black tank on fields or in ditches or any place that it is not designed for waste but many of the companies in my area who pump residential septic tanks for a business spread the waste they collect on fields where non agricultural crops are grown.
Waste containing industrial chemicals are not allowed to be spread on fields and must go to a sewage treatment plant..
I stopped at the store today and they had 2 types of black tank chemicals for sale
. One said NO formaldehyde and biodegradable ,the other had warning labels all over the bottle . The biodegradable stuff was considerably more expensive . Guess which one most people would buy.
