Sludge Reducer

It is a warm weather product basically. It won't harm anything but won't have any effect in cooler temperatures so do not use it in water that is less than 60 degrees Fahrenheit. BREX

As long as the pond was sealed properly, yes. BREX

No, not at all. I like to sprinkle it over the water though, and then take a hose and spray the surface to push it downward. Assuming you are using the powder form.... BREX

This is an enzymatic product, and it slowly dissolves over a period of a month, so yes, as long as they don't get it and eat the entire thing, it's fine. Keep in mind, pond water can harbor various bacteria and protozoa that can affect your dogs, however. BREX

Cleaning the pond completely means removing all of the biological filter and it has to re-establish one. Also, Pond Block should not be used with live plants so the plants probably are not doing much at this point. Test your water quality to see what is off, and add a bacterial supplement/treatment. You don't mention any equipment such as filters or UV lights, etc. You may need to add some of these to help clear the pond. BREX

You would use about 1/4-1/3 if you can cut it into that size. Always better to under dose something like this, then over dose. BREX

Yes, that's fine. It helps to break down sludge, it does not help remove algae. BREX
