I just put this into our black and grey water tanks, so I am anxious to see how well it works. The color is a nice orange, like the fruit, which smells great as well. I like that the container has the measuring which also is amazinf. Will make adding to the pluming the best. The container also seems very durable and the caps seem to go on tight. No worries of spilling and harder for out dogs to get into. I also felt the price is affordable so if this works like I am hoping, I will purchase again. My son, dogs and I live full time in our camper. With winter approaching, I am hoping we won't have septic issues, like we had last winter. But that was a my fault issue. Over the summer, when it was time to drain our septic, I knew because the camper got the foul smell, and upon draining and airing out the camper, that awful smell would go away. I also noticed we were draining every 2-4 days. Mind you, I was using some pods that were recommended by a few other people living in campers. The only thing I used, so I am searching other things to use that may be better. I will later update how well. But it arrived when it was supposed to and smells like citrus and nice. The package it arrived it even has the smell. Update: I've been using this for a few months now. Works like a charm. I don't have to drain the poop shoot or the grey water tank for 3-4weeks, vs 1 week, yes, j used his in out grey water tank too. That for me is awesome! Update: I don't have to empty our takes for almost a month! We still like in our camper full time and use the toilet several times a day, use shower at least 2x a day and wash dishes. It's great compared to before using this stuff.

Liquified is simply the best! While there are other similar products on the market, the formula used by Liquified gets the job done. The RV black tank is usually not something people like to talk about, but Liquified definitely helps the black tank to smell better and function more effectively. The bottle is very convenient for measuring just the right amount of Liquified to pour into the tank. The value for money is good, and the product just works. Can't ask for much more than that from an RV toilet treatment.

Great product! Our tank had stuff blocking the sensors so we never knew how full it was. This was the only product that worked to clean things up. If you know...you know!

The Perfect Partner to Unique Digest-It+ – A Double Whammy for Black Tank Maintenance I use this Matts RV Reviews Liquified RV Toilet Treatment in conjunction with Unique RV Digest-It+, and together they make an absolute double whammy for keeping the black tank clean, clear, and odor free. The orange scent is pleasant and fresh without being overpowering, and the digester formula does an excellent job of breaking down waste and keeping things moving through the tank the way they should. Used alongside Digest-It+, I've noticed a significant improvement in overall tank performance, odor elimination, and peace of mind knowing I'm giving the black tank the best possible treatment on every trip. The combination of both products has made black tank maintenance one less thing to stress about on the road. For any RV owner serious about proper holding tank care, pairing these two treatments together is a strategy I highly recommend. This one earns every bit of 5 stars as part of that routine.

I absolutely LOVE Liquify blank tank treatment. It comes in a wonderful bottle that eliminates the need to measure the liquid each time. I can say that we have never had any leaks with this bottle. It has a nice scent that is light, not overwhelming. The product lasts for a long time, such as when the RV is in storage and the tank hasn't been dumped since the last use. Through the years, I have used many, many products in the black tank of our RV. There is nothing that even comes close to this product. It is a great value for your money. You will not be disappointed if you try Liquify!!!
