Instructions
  1. Before installation, soak the sponge block in aquarium water for at least five (5) minutes.
  2. To clean sponge block, always rinse with water taken from your aquarium. Do not use tap or hot faucet water as this can damage the sponge block and impact bacteriological action.
  3. When re-installing the sponge block, submerge in aquarium water and squeeze gently to remove all trapped air inside the microscopic pores. This allows the sponge block to operate properly.
  4. For optimum performance, replace the sponge block every six (6) months. Allow the new block to soak in your aquarium water for a minimum of two weeks before installation to allow it to colonize with nitrifying bacteria.
  5. The Bacto-Surge® Sponge Filter requires a minimum of 30 days of use to operate peak performance. Care should be taken during this time to monitor your ammonia, nitrite and nitrate levels as the aquarium progresses through the nitrogen cycle. ClorAm-X® can help control ammonia toxicity during this period.

    Seems to be working ok

    By frodosmom on Oct 25, 2020

    It takes a while, but I've started noticing the water is more clear and crisp looking. It's gentle enough that it won't trap my betta or push it around.

    Great for Betta fish

    By Laura on Jul 11, 2020

    I use a sponge filter for my Betta fish who is in a 5 gallon and so far no complaints! There are always pros and cons with different filters, and I will say I have to clean his tank more thoroughly than the others, but I love that it causes low current and my parameters are usually pretty consistent so I'd say it's doing a good job.

    A good sponge

    By Summer on May 9, 2020

    I ordered the wrong size for the tank but that's on me. I'm still using it though, and it performs well. Safe for my shrimp and livebearer spawn. I let it soak in one of my tanks overnight before placing it. I'm a fan and would buy again for my other aquariums.

    Nice quality

    By Crispkringle on Apr 30, 2020

    Big, good for air pump powered tank filter. Grows good bacteria and some light mechanical filtration. Clogs easily tho if using a powerhead and dirty tank. It's not really designed for that use, too fine. I have several others on air only that work great

    sank right away

    By Nikki on May 12, 2020

    so sick and tired of hang on back filters breaking on me. This sponge filter is nice and quiet, obviously no mechanical bits and bobs to break on you. Finally my tank is sounding great and looking crystal clear

    No Weighted Base

    By Laura on Feb 13, 2020

    What a waste of money. I bought this for a hospital tank, but it did not come with a weighted base. I needed it immediately, so decided to give it a try by weighing it down with rocks. No go. The slightest movement from someone walking by, and this thing pops up. Super stressful for sick fish to listen to falling rocks and have the water flow change so suddenly. So frustrating!
