Cost is crazy and upsetting.....But I bought 3 muck blocks earlier this year and a large fountain for a 1 acre pond. I dropped the MB's in the last 4 months just below the fountain. Because I cannot see the bottom I must gauge by smell. The smell is profoundly better. The water, due to the fountain and muck block combo, is not stagnat and nothing grew on top of the water besides normal bank weeds. I am so thankful. This is a headache/heartache every single year. My worry diminished. Note: we have had above normal rainfall in CS TX this year and cooler temps but just the look makes me so happy. Thank you.

I placed the Muck Block at the end of our dock. This took place on June 8, 2021. It is now June 18th, 10 days later. Does not seem to be having much effect. I understand it is time time release but I would have thought I would see some activity after 10 days but nothing yet. Still lots of muck around the block and the water is about the same clarity. Disappointed so far but I will check again after 30 days since it is supposed to last 2 months.

Seemed to work very well.

I have seen great improvement in our pond with this bacteria block placed near the fountain. It’s a bit pricey but I think worth it.

Put 3 of these in my 1/3 acre pond. They are having a profound effect in clearing up the organic muck. Bottom is cleaning up beautifully.
