Zoe Alsop –
I’ve used these cartridges for three months now and noticed a big improvement in water clarity. The tank smells much cleaner and the fish seem more active. Easy to install and fits perfectly with my E-filter.
Ryan Arnold –
Works well with my undergravel filter. I replace them every 3 weeks and the water quality has stabilized. A little more expensive than other brands, but the performance is worth it.

Great product for maintaining chemical balance. The odors in the tank have reduced significantly. I noticed less discoloration in the water after switching to these cartridges.
