Great choice for my planted tank. No carbon means my plants are thriving without any discoloration or nutrient loss. Fits perfectly in my Emperor filter and has been working well for over three months.

I was worried about carbon affecting my live plants, so I switched to this carbon-free cartridge. Water clarity is excellent and my anubias and java ferns are growing strong.

Works well with my Emperor filter. No carbon is a big plus for a planted setup. Slight delay in installation, but otherwise very reliable.
