Lee's Dual Action Foam Filters are biological filters composed of open-celled foam which provides enormous amounts of usable surface area for beneficial bacteria to colonize. This bacteria breaks down harmful waste substances (ammonia & nitrite), making your aquarium a safer environment for your fish to live and breed. This fundamental filter is excellent for breeding all types of aquarium fish, as well as for hatching and raising brine shrimp as it will not trap nor harm them. Great for fresh or saltwater aquariums up to 5 gallons. Shipping weight: 1/3 lb.
Even though these were running behind due to issues beyond petguys control, they got here, and we were called at home, which was a nice touch. This product is excellent, long lasting and working great. I look forward to future business.

Good filter for fry
This filter is good for a tank containing fry as they are not sucked into the filter.
