- Before installation, soak the sponge block in aquarium water for at least five (5) minutes.
- 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.
- 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.
- 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.
- 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.

Not good at all
By Doris on Oct 12, 2021
Base is not weighted and the sponge just floats to the top. It needs either a weighted base or something to anchor it to the tank. For the price you can get better like Seapora.

AIR PUMP NOT INCLUDED
By foamfilter on Jun 26, 2021
Amazing!! Works great!! A little bigger than the picture makes it seem. As a first time fish owner and doing this by myself I had to learn that It dose not come with an air pump the hard way. Other than that wonderful product!!!

Pretty big
By Angel on Apr 30, 2021
The size is deceiving! I don't have a problem with it being bigger than I would have liked, it just doesn't look fantastic in the background. It is a good hiding place for fish though so I'll give it that. It filters wonderfully though, my water was a bit cloudy and within a few hours, it was sparklingly clear. Shrimp will like to eat off of it so that's nice as well. Follow the instructions and it should sink down without a problem, just have to get the air bubbles out.

So far so good
By Nice on Mar 21, 2021
This sponge is big. Whole lotta surface for that bacteria to thrive. Did have to make a small altercation to add my own air stone though, which of course will void any type of warranty. Other than this I have no complaints.
