Every time I use the commode I put bacteria in it I don’t feel that it’s necessary to put artificial bacteria in the commode to eat up the waist
I don’t leave the Blackwater gate open only open it to dump
In the last three years I have had no problems

I use the natural addatives made by unique. Ive used both the drop ins as well as the liquid. Worst thing is during the summer heat…theres still ordors when doing a full flush. If i maintain a half full bowl and do a half flush…no odors. I live FT in a stationary location and find this product to be very effective. To clean the bowl, shower and the sinks, i use simple green…as it doesn’t interfere with the natural enzymes in the unique products.

No commercial treatment for years. Only use Costco drop-in laundry detergent in black and gray tank. If we do get any oder will add pinesol. I answered no to survey.

I use Tank Tech, in the black tank and Happy Kamper in the grey tank. Every time.

A copious amount of Campa Chem does my black tank well. It also helps my gray tank.

You need to define “additives” as either commercial rv tank additives or non rv tank additives. For instance, I only use a cup of liquid laundry detergent and a cap full of Calgon water softener in both my black and gray tanks along with about 5 gallons of clean water whenever i travel. At the next destination, I drain and add about another 5 gallons to both tanks. I repeat this procedure every time we travel. So…. I answered “NO” as i don’t ever use any commercial rv tank additive of any type.

I take an empty one-gallon jug to which I mix a cup of Calgon bath beads and 32 oz of PineSol. Careful. Do this slowly as you will get a lot of fizzling foam. Once this slows down, finishing filling the jug with with water, near the top. With your new brew, add about a cup to your toilet and flush. I will usually add a cup, every other dumping and thorough rinsing. I will also use a Bio tab (greenie), supposedly organic. Available from Walmart. Take the time to do a rinse each time you empty.

Be aware that Pine Sol is a petroleum based product and is detrimental to rubber and plastic gaskets/seals. Better to use a pine scented product like Pine Power…you will get the same results in tank cleaning.

Rid-X RV and Happy Campers are my go-to tank treatments that I like to use.

If moving I use nothing. If in a park for a week or longer,Rid-x. I trust the bacteria to work. Never had a problem but like they say” an ounce of prevention is worth a pound of cure.

Good dose of Rid-X. Controls the odors, digest everything to liquid, helps keep the sensors clear. Also after every dump I use the black water rinse, and when driving add a couple gallons to swash around and soon after setting up at our next stop use the black tank rinse and dump again to give the tank a deep cleaning. Never have any issues.

I’ve been using BIZ Laundry Detergent for years. Claims to have enzymes that eat up the stains, and well you get the picture. Main thing is it works!
No odor issues and no sticking valves. I use it in both black & grey tanks.

15 years full-time and have only used water. Once in a blue moon, we have used rid-x when we will be away from the motorhome for a week or more. No problems so far.

Hi, Dave. Hey, there’s a blue moon on Halloween this year. Better get your Rid-X out. 😆 Take care. —Diane at RVtravel.com

Absolutely do insert additives. Calgon and dawn as well as a digester product. Plenty of water added after each dump and flush procedure

We always add one ‘helping’ of whatever black tank chemical we’re using when traveling normally (moving every week or so), but right now we’re motionless for about six months so we add a double dose of the stuff. When we dump, we use the rinse thing several times to get clean (or as clean as you can get when the rig is motionless). Then we add 3-4 gallons of water.
