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

These balls are geared toward keeping tanks crystal clear—each one packed with beneficial bacteria that break down waste and boost biological filtration. Ideal for tropical or coldwater setups, whether you’re running sponge filters, external units, or internal boxes. Just drop them in—no measuring, no mess. Works well in tanks that get cloudy or need a boost after water changes. Fish stay calm, water clears up fast, and filters run smoother. Great for van setups, pet stash, or home aquariums where you want low-maintenance clarity. No smell, no residue, and safe for shrimp and snails too. Best used weekly or after filter clean-outs—keeps bacteria levels topped up without overdoing it. 👍 Pros ✅ Easy to use—just drop in ✅ Clears water fast—visible results ✅ Boosts filter health—supports bacteria ✅ Safe for all species—fish, shrimp, snails ✅ 50-pack—lasts months with regular use 👎 Cons ❌ Not a chemical—takes time to work ❌ No resealable pouch—store in tub ❌ Won’t fix poor filtration—needs working setup

These Evolution Aqua Pure balls are fantastic — they’ve made a huge difference in keeping my tank water clear, clean, and healthy. Within a few days, I noticed less waste buildup and a big improvement in water clarity. They’re super easy to use — just pop them into the filter or directly into the tank, and they do the work for you. Safe for fish and plants, and no mess at all. The 2-pack is great value and lasts a long time. Highly recommend for anyone who wants a cleaner, healthier aquarium with minimal effort! 🐠💧

I was a bit sceptical given the mixed reviews but they do work in a small 65ltr aquarium with 6 minows and a large shrimp with attitude. I was having to do a 50% water change, clean the glass and filter and vacuum the gravel about once a week before trying these - you do have to put them into the filter not lose as it suggests but the water is much clearer and doesn’t smell so much and reduced how much I have to change the water (50%) to about every 2-3 weeks so well worth it - I use about 5 balls in a PF2 under the sponges and they last about 7-10 days - will buy again

Worked like a treat, fish tank clear again .

Seems to work much cheaper than the most expensive brands

Confused. The Amazon advert tells you to put these directly into the aquarium, and it helps clear green water. The instructions on arrival tell you that they are not to clean green water and they should be placed in a filter bag, not directly into the aquarium!

Water is much clearer with this product

Brilliant they do work i put in side the external filter. I was recommended by aquarium shop

Product doet niet wat het beloofd

Ich habe vor ca 4 Wochen mein Aquarium umgestaltet neuer Kies neue Wurzel und neue Pflanzen. Ich hatte das Problem das die Wurzel trotz wässern weiter das Wasser eintrübte... Nach der wasserwechsel nix brachte habe ich noch einen Wasserwechsel gemacht und Bälle in den Filter mit reingemacht. Und siehe da es hat geholfen... In wenigen Tagen wurde das Wasser Glas klar und der Filter läuft mit voller Kraft... ich würde die Bälle wiederbestellen nur schade das der Preis so angezogen hat...

Hjälper inte ett dugg, helt värdelösa!

After trying everything for 6 months and nothing working to get rid of my ammonia problem I used this product and 3 days later my ammonia was 0. It has stayed 0 for 2 weeks. I have a 20 gallon tank and put 6 balls in my filter media. I have bought 2 more boxes. Will be using this from here on out.

En principio funciona bien, no hace milagros pero si se nota el agua más limpia de lo que solía estar (acuario con tortuga). Son bolitas de gel que una vez dentro del acuario en el propio agua son imperceptibles. Suelen durar (ser eficaces) una semana o 10 días maximo cada una. Vienen recipiente hermético. Bien presentado, de calidad.
