Shop Evolution Aqua filter media and aquarium and pond bacteria products at The Tech Den Australia. Explore K1 and K+ biological filter media alongside the PURE range for freshwater aquariums and ponds.

K1 and K+ filter media

• K1 filter media in 1, 25 and 50 litre packs for compatible static and moving-bed filtration systems.
• K-Plus advanced filter media in 1 and 25 litre packs for compatible biological pond and moving-bed filters.

Check media dimensions, filter compatibility and the recommended media volume before choosing a pack. Moving-bed systems also require an appropriate filter design and aeration.

PURE aquarium and pond bacteria

• PURE Aquarium in 25-ball and 50-ball packs, plus PURE Aquarium Bomb for freshwater aquarium cycling and biological filter support.
• PURE Pond 500ml and PURE Pond Bomb bacteria and enzyme products for pond and biological filter care.

Choose the aquarium or pond product suited to your system and follow its individual dosing and application instructions. Continue regular water testing and maintenance; bacteria products do not replace an appropriate response to ammonia or nitrite readings. PURE Aquarium Bomb and PURE Pond are not intended to clear green water.

Choosing and ordering

Compare the product instructions with your aquarium or pond volume and filtration setup. Larger K1 and K+ media packs carry additional delivery charges for bulky items, calculated at checkout. Check each listing for details.
