KascoMacro Zyme Time Release Muck Block Beneficial Bacteria | Muck Remover for Ponds & Lakes | Non-Chemical Lake & Pond Treatment for Eliminating Sludge & Odors | Treats Up to 6 Acre-feet 6 lb.

For the price works great toss in pond an forget about it

In the past I have applied a liquid cleaner atleast every 3 weeks. This is so much more convenient. Its been less than a week and the water is much more clear. I have an aerator so it does disperse through out.

Might or might not work at this early date, advertising indicates it would be gray in color which doesn’t attract attention.Will see if the muck block does anything that could be detected in the next 2 monthsUpdate: did absolutely nothing! DO NOT BauY

This block is supposed to be for much larger ponds than my 5800 gal. one, but I was having such a problem establishing a balanced ecosystem with crazy long string algae taking over, I bought it. That was about 3 weeks ago and I'm not sure it's made a difference. Currently, the algae has not increased, so maybe that's due to this marine bacteria block and the liquid bacteria I've added. As a standalone treatment, I don't think it would have much effect on the filamentous or planktonic (green water) algae. You need to combine forces with liquid bacteria.A few side notes: the bright, turquoise color of this block surprised me; it's not gray, like in the image. It was very visible on the bottom of my 4 ft-deep pond until it finally dissolved after about a week. Also, once I got it wet, it crumbled easily, so relocating/moving it is not a good idea.

I have tried many muck busters over the years with various success and failures. This product started to show results in 2 days and the best part about it that you drop it in and forget it. No dosing , no timing , no mess (liquids).

Synopsis "It restored my septic drain field"Since it is a facultative bacteria colony forming product, and since I use a large aerator in my septic system to support aerobic bacteria digestion of waste, I gave it a try. Yes it says it treats two acre feet of water, and yes that is the standard equivalent of two years water consumption of a typical household. But hey septic systems are not equivalent to a typical pond.I dropped the six pounder next to the aerator in the sewage pump tank, the bacteria consumed the biomass buildup and within 6 weeks the water standing over my septic drain field was gone. That was equivalent to letting the system "rest" unused for 12 months. Minus 1 star for price 😁

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.

I have tried a couple other muck blockers. This one worked quickly and did a great job. The first time I'm purchasing the same muck remover product twice. If you have muck- give this a try. Safe for fish and pets.

I would like to believe that it did work as promised but it did eliminate the odour. As far as the silt goes I think I was short on my calculations. By that I believe that I should have used 2 of them.

Wish I could rate a zero. This does absolutely NOTHING. This is the biggest waste of $175 plus.

Only one block used in an area which has lots of muck. Too soon to tell
