Energen Grey Water Tank Treatment - Holding Tank Odor Control and Cleaner - RV Water Tank Deodorizer - 32 Ounces

Our ignorance of gray water treatment caused really bad odors started to come out of the sink when the tank came close to full. This treatment works really well when used as instructed. Clean smell. Works good.

I had to use the one ounce dose several times over the first week to conquer to swampy smell, but in fairness I did not empty and clean the tank first. Now that I seem to have a handle on the problem I am satisfied with this product. I will be curious to see how long this little jug actually lasts me.

This really stopped any smells coming from my gray tanks.

This is an awesome product. We used the recommended amount in outer grey water tank for our food truck and it began to work immediately. We will definitely buy again and keep it stocked in our food truck.

Great product

Only used this one tine. No odors from gray tank but we dont usually have any. Too soon to tell how it will work long term but OK so far.

Worked well in my holding tank. This liquid replaced the bad odor with a pleasant smell. The amount of product purchased was smaller in quantity than k was expecting it to be, I should have reviewed the product description closer.

Easy to use. Time will tell with continuous use.
