Just to add that the reason I use only water on grassy areas is that I have a Koi/sterlet pond, it's really hard to find out weather any disinfectants are harmfull to my fish. There are
pond products I can't use for the koi as the sterlet wont tollerate them & vice-versa so I wouldn't want to put thier healt at risk. I've looked at the safety sheet for 'Safe4Pets' and allthough the ad says frienldy to the envioronment, the actual safety sheet states there is no data available for Aquatic & Eco toxicity :(
