The carbon works well to eliminate the yellow tint in my tank. I’ve used it for three months and the water stays clear. Easy to install and fits perfectly in the C2 filter.

Good improvement in water smell after switching to these inserts. I noticed less odor after a week. I’d recommend for tanks with fish that produce waste.
