Q: I've just added Pond HealthGuard™ to my pond and now there is all kinds of foam and suds at the surface and my fish are dying left and right. What is going on?
A: You must have used Demalin in your system at some point in the past. Even if it has been many months ago, it is still present in your system. When Demalin and HealthGuard™ interact you get the foaming that you're seeing. This mixture is very toxic and is what is killing the fish. The only way to get rid of the Demalin is to do a 100% water change. We don't address this issue on the label because Demalin is a FDA controlled substance and technically you probably shouldn't have been using it all.
Q: How do I determine the exact gallonage of my pond in order to properly dose with Pond Healthguard™?
A: To calculate gallonage, multiply average length by average width by average depth in feet and multiply by 7.5. To obtain average dimensions of irregular shaped ponds (e.g., kidney), take as many measurements as practical to avoid overestimation and consequent possible overdose. Account for water displacement by potted plants, rocks, or other decorative materials. Dispense product widely to avoid localized overdose.
Q: Is Pond HealthGuard safe for snails (rams horns and black melenthos) and frogs?
A: Pond HealthGuard is safe for all pond inhabitants, including snails and frogs, as long as the directions are followed. It is a disinfectant that in most cases does not last any longer than 24 hour
