Large double head bio-sponge filters provide both mechanical and biological filtration. Simply install an airline into the unit and provide both aeration and filtration for your fish. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. In addition, the sponge traps larger waste particles. It mechanically cleans the water without trapping baby fish.
These filters are useful as breeding filters, as a secondary filter or they can be used as pre-filtration unit by fitting to an external or a top filter.
IMPORTANT: These sponge filters require 3/16" aquarium tubing and either our DB-300 or DB-333 model pumps to function.
Thank you for submitting a review!
Your input is very much appreciated. Share it with your friends so they can enjoy it too!
This filter seems to be working great. This is our first sponge filter and we bought it for a pair of Rams who seem to be pairing up. The flow is great across the top of the water will still being gentle enough for a breeding tank. We are happy with it so far!
Wow, thanks for all the feedback! We wish you the best for your Cichlids!
I think its pretty good for the price and i would definitely recommend it.
Have not used them yet but nice design
I'd recommend these filters to others. They work very well. AquaDream had them in stock and shipped them quickly. I like the black color.
Thanks for the feedback Kim! :)
My filters arrived in just bubble wrap. They appear not broken but they were a gift so not sure how they worked
We're sorry to hear your disappointment with the packaging Amanda. If you find they are broken, feel free to contact us for a refund.
