Frequently Asked Questions

Do HOB filters provide enough oxygen?

How long do HOB filters last?

HOB filters can last 4-5 years or more with the proper maintenance and cleaning routines. Some options will even come with year-long warranties to guarantee it. It’s one of my more valued attributes when buying a HOB filter for aquarium tanks.

But the one issue is HOB models do require a bit more cleaning than canister filters. To maintain it, buyers must clean them out at least once per week or bi-weekly. If you do, the filter will be fine, lasting as long as possible.

Is a sponge filter better than a HOB filter?

It depends on what you want in your tank’s filter. In other words, there are situations where a sponge filter would be a better fit than HOB filters and vice versa.

For instance, sponge filters are more suitable in basic tank setups with a flow rate lower than 30 gallons/hour. Therefore, it makes a better choice for people who want something simple and affordable. After all, sponge filters tend to be much less expensive than HOBs or power filter aquarium models.

On the other hand, HOBs are better in tank setups with a high flow rate. These options are also known for their endless versatility concerning filtration media. HOBs are more efficient and productive than a typical sponge filter.

So buyers must determine whether they value simplicity or efficiency when choosing between these two filter types. In my case, I’ll always select a HOB like Seachem Tidal HOB Filter due to their practicality.

How do you get grease out of a HOB filter?

The most suitable way to remove grease from a HOB filter or a power filter for fish tank aquariums is by using tank water and sponges/brushes. Use the tank water to rinse the grease while scrubbing away hard grease deposits.
