    Our fish tank was very cloudy, so I had a look online and came across these. Reading the reviews I thought I’d give them a go, I put them in at 8:30 pm and took a picture 9am the next morning, and the difference in so little time is fab. Il be buying these again.

    4.0 out of 5 stars make sure you put them in the FILTER or bag
    By Ian on 21 August 2019
    just a precaution I found the balls have not dissolved properly in the filter so if people are dropping them in the Fishtank ? DO NOT as you can see from the picture they do not dissolve properly after a week and half some have dissolved to small rubbery balls the fish may eat them if they was to get in the tank my piranhas eat anything that comes near them so they would have swallowed these undissolved little balls if they was in the tank

    By Theresa on 21 August 2018
    Really great product we have a small 10ltr tank with 4 tiny fish in we were changing the water and filters every two weeks, we have been adding one of these balls a week and we haven’t had to change the water for 5 weeks and only need to change one filter every two weeks rather than both filters. 100% would recommend this product. The water is clean and clear and our fish seem happy. The water in the photo is 4 weeks old!

    5.0 out of 5 stars Brilliant Product - Took a view weeks to lower levels 👍
    By Whitread20 on 16 February 2019
    I purchased a tub for £8-67p with 50 Evolution Aqua Pure in it, for my 100 litre aquarium as you can see from the picture below the first one...my Nitrite and Nitrate levels kept coming in high and for my 100 litre tank i added a net in the left hand corner of my second picture with 8 balls inside.

    I didn't need the product to clear my water as you can see from the first picture...as i add AquaSafe to my water besides API zyme and stresscoat.

    I'm very pleased with the product and shall be purchasing more...highly recommend.
