Is Hydro Vescense™ toxic to fish?
Hydro Vescense™ will not harm any type of fish (including koi and trout) when used as directed. In fact, here at Russell Watergardens, we spread Hydro Vescense™ over all our display ponds by tossing it over the water by hand – and the fish just swim through it as it sinks with no problems. Stop by some time and ask for a demonstration. Just be aware, as with any other cleaning product, if you allow large amounts of build-up to decay within your pond it may cause dissolved oxygen to drop to dangerous levels. Make sure your water is heavily aerated either with waterfalls, fountains, or submerged aerators during Hydro Vescense™ applications. One way to avoid this problem is to treat early – before the water feature is fully loaded with build-up.
