Pond & Lake Q & A

Q: I have a pond that the dogs swim in almost everyday when the weather is warm. It is overrun with Algae. Is there a chemical I can use to kill the algae but not affect the dogs? – Corinne of Ohio

A: Another Great Question! I talk to quite a few pond owners who have pets that love to play in their pond and this is always a concern when it comes to treating a pond with algae. The answer is yes, there are treatments you can use to kill the algae and not harm any pets. One such product is Algae Defense.

Algae Defense is a liquid algaecide that has no “water use” restrictions such as irrigation, swimming & other recreational activities. We suggest to use Algae Defense in ponds that do not contain koi, goldfish or trout. They are very sensitive to this treatment.

If your pond does contain koi, goldfish or trout we would suggest to use a product called Hydrothol 191. The only downside are its restrictions. With dogs or other pets, we would suggest to keep them away from the pond for 7 days if possible.
