Pond Boss CBBPR5 Pro Block Bacteria, 5-Pound

Convenient and one of the better muck reducers I've used for my pond. Bottom noticeably cleaner after only 1 week.

Pond had a heavy algae load. This combined with pond dye has dramatically improved the water quality.Prior to this we tried alternating the jugs of bacteria and algaecide with very little improvement.

Product came quickly and is as described.

I was skeptical when I first purchased this, but the price was right and the reviews were good, so I bought it. Well, it has been only two days and I'm already seeing remarkable improvements in the looks of my 1 acre pond. I purchased this to help clean up the muck that is at the bottom of the pond, but in two days it has cleared up 85% of the algae that was floating on top and I can also see that the clarity of the water is better. I'm excited to see what it looks like a week from now. I cut the block in four and threw it into four different sections, so that may have sped up the process. I'll definitely be purchasing this again in a few weeks and throwing in another one in order to keep the pond clear through the whole summer. I definitely recommend this product.

Has eliminated one third of the sludge in our pond over the last 2 years. Non toxic and easy to toss in pond

We've had algae problems in our pond for the last 4-5 years and have tried everything from carp to colorant to algaecide with absolutely no positive results. Within 2 weeks of putting the Block (2 in our pond), we've had an approximately 90% reduction in algae, no growth or blooms and the pond cleared up significantly. I'm a believer. Will definitely continue to use as needed. Great product! Thank you.

The Block isn't magical but compared to other products, I think it excels in both use and price. Simply unwrap the block and toss it into the deepest area of your pond and let it do it's work. You can start to see results in as little as a few weeks. But remember, this is not a one and done process. Ideally, you should drop two of these per year, or at least one annually. I'm happy with the results and will continue buying.

Well …. I wish I had more details was kinda excited but it got lost somewhere so I didn’t reorder I bought muck tabs and seems to be working very well so far. Pond water is brown so I know it’s taking care of leaves and whatever is down there. Sure wish they’d send me one so I could try it out
