How long it takes to see a result?

Time for results to appear varies with each and every pond. Results are best when the application instructions are closely followed and when the pond has an aerator or water fountain running in it to assist with maintaining good pond health. Please call us at (833) 779-2837 to speak with an aquatic biologist who can better answer your specific questions. Thank you and enjoy your pond!

Have an acre pond how offen do you put these in how long do they last?

I think varies a lot. Our pond stays on the cool side and the pellet slow disappeared over a 3 to 4 month period. Have seen a huge difference in muck. This will be my third year using them.

Where is this manufactured?

All Kasco Marine beneficial bacteria products are manufactured in the USA. Please contact us at (833) 779-2837 if you have any questions. Thank you and enjoy your pond!

How big are the blocks? Are they the size of a softball?

The Kasco Marine Muck Block is a little bigger than a softball. Please let us know if you have any other questions, you can always reach us at 833-779-2837. Thanks, CSJ&J Aquatic Gardens
