FAQ
How often should I replace the activated carbon cubes?
Replace the carbon cubes every 4 to 6 weeks depending on tank size and fish population, or when the water starts to lose clarity or develop odor.
Can I use the small cubes in a large aquarium?
The small cubes are best suited for compact tanks. For larger aquariums, use the large 10×10×10cm cubes to ensure effective filtration.
Does the carbon block remove harmful chemicals from the water?
Yes, it effectively removes chlorine, chloramines, and organic impurities, but does not remove ammonia or nitrites. For complete water balance, use with a complete filtration system.

The carbon cubes work well in my 20-gallon tank. Water clarity improved within a week and the odor has been almost gone. I used the small cubes and they fit perfectly in my filter. Easy to install and maintenance is simple.

Good filtration results after a few weeks. The large cubes are sturdy and don’t break easily. I noticed less fish waste buildup. Would recommend for medium to large tanks.

My betta fish now swims more calmly. The water looks cleaner and the smell is gone. The honeycomb design seems to work better than flat carbon. I’ve used it for two months and it’s still effective.
