Evolution Aqua Pure Aquarium - for a Crystal Clear Healthy Aquarium (50 balls)

This is a completely new concept to me, but one I was willing to try in cycling an aquarium that's live planted and has some delicate species. So easy to use and absolutely they work! After completing a water change, and disturbing the live planting the water was left a little cloudy. Popped the recommended amount of orbs into the filter unit, and in what felt like no time at all, the water quality improved and was crystal clear. The fish are unaffected and I'll be interested to see if they make a difference to the health of the live plants. Brilliant stuff!

Works , easy to use

The outside of the box says drop straight into aquarium but the leaflet says add to filter. My tank has a separate area at the back so I dropped them into that space. I used them in my Dad's tank years ago and added them to the filter in a Biorb tank. I believe they do help with keeping the water clean.

Perfect for turtles and pleco

Great as described and a great price

This product is essential for supporting the life cycle of fish in your aquarium. However, I noticed that the balls are smaller than expected, and there are other products available that offer larger sizes. One well-known brand is Pure, which is a valuable addition to your tank for maintaining fish life.It will improve water quality.

My first time using this product, put two in my tank as the water wasn't fully clear and within 3-4 hours the tank only crystal clear. Will be using these from now on

Now I purchased these on a whim. I've been doing large water changes as tank water was a bit greeny. But it wasn't clearing it. It's a heavily planted aquarium.Within 48 hours the difference was remarkable! Super clean water and the green tinge has disappeared! Will be using these regularly now. Would highly recommend to anyone. Plus they are so simple to use!
