great for planted aquarium
I use them for my planted aquarium. Hydro filters do filtering very well. However, if you cannot stand any bubble noise, these filters may be not for you. However, compared to other sponge filters with inverted L-shape outflow tube, Hydro filters are much quieter.
Since Hydro filters must be placed inside your tank, unless your tank is big or you have many tall plants to hide them, they will be seen and take some space. But, these filters cannot be beaten with their simple setup and easy maintenance and effectiveness.

Provides beneficial bacterial an keeps tank cleaner
I recently purchased two Hydro-Sponge Pro Filters Pro II . I'm using one in a 55 gallon tank and the other in a 37 gallon tank. I also use hang-on back filtration. I read that the sponge filters helped to remove fish waste and provided beneficial bacteria. My hang-on filters were clogging up and I needed additional filtration to releive the build-up on my filter elements. The Hydro-Sponge Pro Filters are doing a great job. I used to change filter elements on my hang-on filters once every 10 days. Since installing the Hydro-Sponge Pro Filters I have not had to change one and the sponges have been installed for approximately one month. I wish I had known about them a long time ago. I could have saved myself a lot of money on filter elements. I am very pleased with this product and I would recommend them to any fish keeper interested in supplementing their filtration.

Excellent Sponge Filters
I these days of HIGH tech lights and filters for fish tanks sometimes the simplest design is still the best. That is what you get with Hydro Sponge Pro Filters, excellent biological filtration and easy maintenance.

Needed an add-on for my canister filter
While at the local fish store I noticed they had sponge filters in all their tanks and wanted to give one a try in my 55gal tank. I have a OTB 110 filter and it kept the water good but not polished. Adding the sponge filter seemed to help polish the water so I bought a larger one for my 125 gallon tank and that one is also looking better. Will put a battery back up air pump to both of these just in case the power goes out; cheap insurance for protecting my fish. Great product and fast delivery.
