Easy to order and use. Does what it says and stops the water becoming stagnant. Would recommend.

Goods arrived quickly and well packaged, thank you. Always a pleasure dealing with with this company.

I’ve used this now every year, about twice a year keeps my koi very healthy in there environment

I haven't seen any slugs or snails since I started using it, so great product!

Order was dispatched quickly but have only just used product so can’t rate as yet. However if it’s as good as the other products I’m sure it’ll be great.
