Sarah L BailesSarah L Bailes: I absolutely love these tabs. My pond is in the sun all day so algae was kicking my butt. It’s a pain to try to drain down scrub and keep the pond clear. I put one of the tablets in the waterfall and within a week my pond was crystal clear and every piece of algae was gone. I had quiet a bit of algae buildup prior. I have river pebbles on the bottom of the pond and they were all green now look wayyyyy better. My waterfall was completely covered in algae as well. I have about a 500gallon pond but only use one tablet at a time. Being in the waterfall I have to replaced about once a week vs month Now that the algae is under control I’ll probably just drop one by the pump and replaces as frequently.

laura: These are very easy to use as there is no measuring involved (Once you've determined your volume, you're all set), I really like that! They do a good job of helping to keep the water clear. I throw them in our pond every 30-45 days, depending on the time of year. It's changed my pond experience from a battle to get the cloudy, mucky water back under control once or twice a year, to practically care free. I've been using for about a year now and have had no adverse reaction with our fish or plants. The current ones are not always fully dissolved when I add new ones, that seems to not be an issue. The only negative would be if you don't want to see the little squares in (bottom) your pond.

MuffinMuffin: Have been looking for an effective algae control product for our pond but none worked. Thought to try after reading reviews as we have a lot of sun. We have to use 2 blocks instead of one to better control the algae. Will definitely buy more.

mlphmlph: Update 6/15/16- I have already purchased my second package of these, I am that happy with the results. I had to use a few to get it going, and then I think my turtles ate one! Seriously, it was only half dissolved this morning and now it is gone. They are acting fine, added a new one up on the waterfall so they can't get at it this time. I will never be without these again. Will look into getting the big tub of them next time.
My pond was a big green mess. I previously tried barley bales and liquids which did nothing at all. I decided to try these algae control blocks and am glad I did. I just received these 2 days ago, and already I can see my fish, turtles and the bottom of my pond again. Still has a ways to go to be totally clear, but I am amazed. I dropped 2 of these tablets in along with one of their sludge reducer blocks. My pond is not large, it is a preformed plastic one we bought at Home Depot, I think 250-300 gallons. Nothing I have ever tried has worked, summer is the worst, full of algae all season long. As well as being able to see to the bottom and my animals again, the walls of the pond are clear from the thick algae that was growing. I don't have any plants in...
