Is this product poisonous to fish

I would not use this where fish are present.

Curious to learn if the successful comments relate to positioning of water-butt? Can anyone confirm success where water-butt has some exposure to sun?

My water butt is always in the sun but I keep it covered to preventing and protecting it from the sunlight and that prevents algae forming, still needs checking every so often.

Could this product be used for a water feature in the garden? Over winter, the water has acquired a nasty smell?

Hiya, I haven’t used it in a water feature, only water butt. I have water features and used a product called ‘Sparkle’ that clears green water and is ok for wildlife to the water.

Is it suitable after treatment to use the water for watering vegetables/plants in an allotment please

I don’t use the treated water for veg, only to water flowers, shrubs etc! Not had a problem with it that I am aware of!

A trusted product.

After a long period of high temperature and little rain. One of my 100litre waterbutts which gets a lot of sun started to smell. Not really sure about how much to use I gave it two measures. It killed the smell.
