    absolutely the best for my turtle/Goldie pond

    By on

    Hands down the best algae and sludge and cloudy water cure I have ever used in 12+ years. I have don’t the liquid pour in, the rock salt in the filter, vacuuming daily, you name it-we’ve used it. I got these on a whim and thank god, they have been a game changer. My pond gets full full hot sun all day and turns to pea soup quickly. Sure I get huge goldies from the algae but I look to see what my pond looks like rather than a dark green sludge farm. I have only used 6 tablets in my 400gal pond so far and absolutely loving them. So easy so simple and they work. I can’t rave enough about them. Until your have a large red ear slider, 12+ large goodies and live feeding you have no idea the work involved Hands down the best algae and sludge and cloudy water cure I have ever used in 12+ years.

Until your have a large red ear slider, 12+ large goodies and live feeding you have no idea the work involved in keeping a pond looking somewhat ok. Now my pond is crystal clear, the rocks inside aren’t even covered in algae anymore. Like I said hands down game changer and now a customer for ever. … more

    Poor packaging

    By on

    The package was not properly packaged and arrived two weeks after the order. Although the box was undamaged, the lid of the jar inside was broken into three pieces and all the contents were scattered inside the box

    Highly recommend

    By on Top 1000 Contributor

    I dont like using chemicals in my outdoor goldfish pond. Last year the algae and sludge were a nightmare towards the end of summer. I couldn't even see my 8 goldfish. Nothing i did naturally helped. After doing ALOT of research on this product, i decided to give it a try. I also use the API Sludge Remover which isnt a chemical. Its been 2 weeks and i can finally see my fish. If your pond is bad, this product will NOT work overnight as some claim. You still need to put some time into helping these products along. At first, i was cleaning my filter pads 2x/day. Now i dont have to change them but once every other day. You also need to net out the dead algae. No scrubbing tho.

I don't have time for heavy pond maintenance so I am glad i found both of these products. I will always keep them on hand plus use the minimal amount just as a maintenance regime. I am extremely pleased with these products and would highly recommend them. But again, you must have patience as these products will not work overnight. … more
