Blue Planet Filter Media for Classic 20/80 6pk
For small tanks - compatible with Blue Planet Betta Tanks, Classic 20L, Classic 28L and Hexy Midi
Small aquariums can become dirty surprisingly quickly, especially in tanks under 30 litres where waste and leftover food build up faster. Replacing your filter media regularly helps maintain clearer water, healthier fish, and better overall filtration performance.
The Blue Planet Small Tank Filter Media cartridges are designed for quick and easy replacement with no cutting, measuring, or mess required. Simply swap out the old cartridge and let your filter get back to doing what it does best — trapping waste, reducing impurities, and helping keep your aquarium water crystal clear.
For best results, most aquarium owners replace their filter media every 3–4 weeks depending on stocking levels and feeding habits. Keeping spare cartridges on hand means you’re always ready when water quality starts to decline.
Perfect for beginner aquariums, family tanks, betta setups, shrimp tanks, and small tropical aquariums from 8–30 litres.
- Suitable for Classic 20L, Classic Tall 28L, Hexy HPLED, Deco-O Mini 10L, Panoramic HD 20L, Betta Plus LED and Deco-O 20L (new versions only)
- Comes in handy 6 Pack
- A small handle is added for ease of change so say goodbye to touching dirty filter media!

Blue Planet Filter...
These Filter Media Blocks are simple and easy to replace and keep our fish tank water sparkling clean. Each block can be cleaned by rinsing out in water several times but eventually need to be replaced a couple of times a year. Having six blocks in the pack gives you a couple of spares after changing four out for new ones. Filter pack is quite inexpensive and easy to change out.

Blue Planet Filter Pack for Small Tanks
Bought these replacement filter modules for my 20 litre fish tank. My filter only uses 4 modules so I will have a couple of spares. They are easy to clean and replace and quite inexpensive. They ensure my tank water remains crystal clear.
