Question: Is Biological Laundry Powder Septic System Safe?

Can anyone tell me if I am correct in thinking that you are not supposed to use biological washing powder if you have a septic tank? Does its use upset the system?
Many thanks.

I believe its safer for the septic system than regular detergent. REgular detergent interferes with the ecosystem in the tank and kills off the natural bacteria. Try to stay away from harsh cleaners that do that.

this past week-end my septic backed up, i've had the house for 4 years, the previous owner said it had only been 5 years since it was pumped, but the septic tank guy said it had to be much earlier since it was only me and my husband who live here it would'nt be that full that soon!
anyway, he and the plumber both said .ridx and other similar products don't work, that once a month flush a pack of Fleischman's Yeast down your toilet even if you have more than one toilet just flush it down one of them this wil help your pipes and your septic tank. also to only use 1 ply toilet paper, 2 ply does'nt disenegrate well and you can block up your pipes more, and don't flush tampons or napkins either, i always inform any ladies who are guest of my house to dispose of another way, they understand the reason and have no problem with my request.

Question: Septic Tank Safe Cleaners

What can I use to clean the toilet tanks? Right now they look black stained. I recently put in a water filtration system and expected to see clear water in my toilet tanks. Instead whenever I open the toilet tanks it is all black. I have a septic system, so I don't want to use anything that will cause a problem with the septic system. Any help would be appreciated.

The water that comes into the house is dispersed to all outlets, the sink, shower, toilet. If the water is not black in the kitchen or bathroom sinks then I don't think the water in the toilet tank is black either. When I took the top of the toilet tank off my tank to insulate the inside of the tank I also noticed black mold on the walls which made the water look black.

I took the tank off the toilet, took it outside and cleaned the tank with bleach. I then insulated the inside of the tank and replaced the tank. If you think the water is black and not from mold on the inside of the tank I suggest you scoop out a glass of water from the tank and hold it up to the light and see what the color of the water or when you flush the toilet look and see if the water is black or clear.

We have a septic tank . The problem we have is the stains that are in the toilet bowls. We have to be very careful what we use to clean with due to the septic tank. Any solutions on how to clean without harming the septic tank?

We also have a septic tank, so we use a very small amount of Lime-Away on a green Scotch-Brite pad and the stains scrub off pretty easily. We've tried using baking soda, but it doesn't work as well as the Lime-Away does with our hard water. Your water might be different. Good Luck. (10/27/2008)

I use a little Comet in my toilet. First flush the commode. Then sprinkle a little Comet and then brush as usual. I also have a septic system. Another substance that wouldn't be as harsh for your septic tank would be baking soda or Borax powder used with the brush in the same manner. (10/28/2008)

I have had a septic tank for almost 9 years, and I use plenty of detergents, bleach and other cleaners. I've never had a problem with my septic system. We do put in the additive stuff that you buy to keep the system working. We've never had a backup or a field line problem at all. (10/28/2008)

RE: Septic Tank Safe Cleaners

I also have a septic tank, and to top it off, water that has high iron content. I had very bad stains. I found a miracle in the cleaner section of Walmart not too long ago. Bathroom Stone. This is not a cleaner, but a stone that looks and feels like pumice, but it's not. It's completely environmentally safe, and chemical free, and I swear by it. I promise you won't go back to chemicals and elbow grease. This is even better than baking soda, Comet, bleach, you-name-it. In case you're wondering, I don't work for this company. (10/30/2008)

RE: Septic Tank Safe Cleaners

All that you need to be concerned about is "killing" the good bacteria in your septic. We have lived with ours for over 15 years. Once a month I put 3 packages of yeast, yes, powdered yeast down the toilet. It helps keep the good things doing what they're supposed to. We have only had to have ours cleaned out once and had no other problems. Don't spend the money on Rid. Just buy yeast. (11/18/2008)

RE: Septic Tank Safe Cleaners

A pumice stick available at hardware stores and cheap will do the trick, with no chemicals unless you count elbow grease. (11/25/2008)
