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

DX50 Water Tank Treatment

Was having SO much trouble with our tank water - test results came back with ecoli 14 times higher than safe drinking levels. The water stunk and it was a nightmare. I shock dosed the heck out of our water with this, the company states 10times the regular dose is still within safe range - so that’s what I did and also poured some down our gutter pipes for good measure. It’s now clean and test results have come back safe to drink. Will now be using this as a regular monthly dose to keep it that way.
So thankful for this product. Will be using this for as long as we are on tank water!

Southwell Fungicide

No smell of dirt etc in our drinking water , bet the cows love it too , good stuff

DX50 Water Tank Treatment

Glad you sold DX50 in 2Ltr containers.
Product working great.
