Lakes: Pellets can be distributed into a lake by a fertilizer spreader attached to the back of the boat. Pellets are typically 1/10th to 1/20th of the cost of dredging.

Decorative Ponds: Pellets are a nice way to keep the pond in check and keep muck to a minimum.

Retention Ponds: Retention ponds start out nice and beautiful and after a few years they become loaded with floating organic matter and muck. Shore Tech Black Label Pellets are an easy way to help balance them out and reduce muck. These pellets will also work well in retention ponds that may have a lot of road salt. A biologically cleaned pond is a happy pond. A mechanically cleaned pond can often be unhappy for some time as it tries to find biological balance.

Golf Courses: Golf courses can get a lot of muck due to runoff, high nutrient loadings, and leaf and grass waste. Our Pellets are an easy and affordable way to keep golf course ponds free of muck and more importantly to help keep them biologically balanced.

Shorelines: Used by homeowners to reduce muck around the shoreline. Just sprinkle some pellets around a dock once a month and let them sink into the muck. Month by month the lake bottom will clean up. Many customers have called them little vacuum cleaners as they see the muck reduce.

Aquaculture: Used to degrade fish poop that accumulates in the bottom of a pond. Our Pellets have proven to be economical and efficient for fish farmers who want to minimize fish waste and muck accumulation as an alternative to dredging.

Q: What kind of muck do the pellets work on? How do you define muck?
A: Weeders Digest defines muck as decomposing/dead organic material that has dropped down to the lake bottom. Our Muck Pellets are designed to effectively target muck as defined above.

Q: Can you overdose on muck pellets?
A: No. Oversaturation of the pellets would be wasting the product, however, there are no adverse environmental effects from putting in too many pellets.

Q: Does the muck ever increase?
A: Early in treatment as bacterial activity increases muck can get fluffier and less dense, however this is temporary. For the best judge of progress, measure initially, and again later in the fall when temperature cools off.

Q: Where do they work best?
A: In organic matter that is humus and has started toe degradation process. In laymen's terms if you step in the muck and it's gooey this is a good application. Works on dead leaves, dead weeds, dead grass, fish poop.

Q: Where do they NOT work?
A: They do not work on rock, sand, gravel or sticks. They work slowly on oak leaves, pine needles and other organic matter that is high in lingin (woody).

Q: Why are these pellets better than other pellets?
#1 We make them small so they cover a much greater surface area.

#2 The bacteria in the pellets are indigenous in many lakes. They are not just from a test tube.

#3 The pellets contain a broad spectrum of organisms. The broader the spectrum, the better the results.

    It really worked!

    Posted by Longlaker on 5th Aug 2019

    Last year (2018) I purchased 50 lbs. of muck reducer and distributed around our dock around the end of July. We had muck that would go up to your knees. As the summer turned to fall I wrote this experiment as a good effort but no cigar! This summer when our grandchildren went into the lake they all stated that the muck was just about gone. What a pleasant surprise. It really worked.

    Been using this two years now, and excellent results! You have to be patient, because it is slow, but given time the muck goes away.

    Posted by Andrew K on 27th Jun 2018

    For the past two seasons I have used shoretec on my new lake home beach. I started with 12 inches of muck at the shoreline and through consistent treatment and manual weed removal, I now have two dock lengths of hard bottom that my wife can even enjoy. Great product!
