Let customers speak for us

We used DX50 to sanitise a permeate tank after fecal coliforms were high at 450 and after treatment it dropped to 30. Very happy with this product.

The product was so simple to apply to the tank and would definitely re-order more. How often would I have to dose I have a 31,000 l8tr tank👍🏽

We have found our water smells better and looks cleaner

Great product that I use for my Peonies! Definitely does the job.

DX50 Water Tank Treatment

Worked well so far

I compared many options for chlorine dioxide but no others came close. I'd prefer a smaller quantity, say one litre, but at this price I can't complain.

Nice clear water again thank you

Great stuff !!!

Good

Test delivered quickly. Easy to use. Fast results. No hassle.

Won't know how well the product works until next fruiting season. If I get no brown rot then I will be happy.

I need someone to call me looks like I bought wrong product

We have been using DX-50 for about two years now and think it is great. Our water supply is tank water from the rain off of our roof. It tastes much better with the DX-50 treatment. We also use a 5ml per one litre of water as a mouthwash each night. It leaves our mouths feeling fresh and clean and prevents the buildup of plaque. Good Stuff !!

Works great with minimal odour
