Oxygen Blocks
Oxygen Blocks – Healthy Water & Active Fish
At Wonderworld Aquarium & Pet Centre, our Oxygen Blocks provide a simple, effective way to increase dissolved oxygen in freshwater aquariums. Ideal for community tanks, densely stocked setups, and planted aquariums, oxygen blocks help keep fish healthy, active, and thriving.
Our range includes blocks suitable for continuous slow release or emergency oxygenation, perfect for use with air pumps, air stones, or standalone in smaller tanks. Easy to use and safe for fish and plants, these blocks are a practical addition for any freshwater aquarium.
