I think the issue most people think they can just throw this in their pond, and everything is going to be the end all fix all. you need. beneficial bacteria You need aeration. You. need Pond dye. combatting algae takes multiple fronts and most people don't know what they are doing. Their pond water is probably really terrible

These bacteria blocks are working well in our pond.

So far it's working well I've only used one block so far on my 120 feet of lake front 🤞🤞

In less than 2 weeks, our lake was visibly cleaner and algae was practically gone. Will be buying this again.

I’ve used this for years. It is a great product. However, the last two orders were basically powder. This might be from shipping, maybe a decline in quality, but, either way, at this price I cannot continue to buy the product. FYI I did have to speak with support early on and they’re great, so it is a shame to see this happening.

I was able to chisel these in two, so a two pack would last 4 months in my 3/4 acre pond. I'm already seeing results.

I added 2 of these at my dock last year. They just lowered the lake and they are sitting under my dock complete intact after two seasons.. Worthless.

I’ve always had a battle with pond scum, duckweed, algae, etc in my farm pond. Used many different products and put in a large fountain.This block placed by my inlet pipe has really done the job!
