Review: Muck Block - 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.
Review: Easy to use! - I can't see that it has done anything for the pond yet!

I can't see that it has done anything for the pond yet!

### ⭐⭐⭐⭐⭐ Works if you do your pre work.
*by D***E on August 29, 2017*

We have a 100 foot x 200 foot pond that receives our flood irrigation water. It has bass and other fish in it. I have fought the algae and weeds for years. This works IF you treat for all the other growth first. Then put the block in and your work is cut down to almost nothing. I use way less Cutrine plus and Weedtrine than before.
