The AquaClear 30 aquarium filter provides biological, chemical and mechanical filtration and was designed for easy use and maintenance. AquaClear Filter media is contained in a convenient filter media basket to hold your filter media in place and make it easy to replace when the time comes. The foam filter insert provides a large surface area for debris and waste retention and beneficial bacterial colonization. AquaClear filters include media cartridges to get you started. AquaClear insert may be rinsed and reused, or replaced when necessary. Pre-measured Activated Carbon AquaClear Inserts eliminate hassle: just rinse and drop in. The premium research quality carbon removes organic compounds and odors.
The filter is easy to setup and it works as advertised. it is quiet. I have it running on a 10 gallon tank with no problem. It holds 3 filtering elements; sponge, biomax for biological filtering and one other for either carbon or amonia filtering.
