I use this filter media in my sump. It works great I like using different PPI material. Before aquarium co-op filter media I just use one type of PPI media and it is restricting too much flow.

Move over, polishing pad. There’s a new kid in town.

We all know about the amazing coarse pad. When optimizing my filtration, coarse pads are my first and main media. I use them in my hobs, box filters and of course, sponge filters. I even use them to create little in tank habitats for black worms. Then, I’d finish things off with the a polishing pad. Worked great except for the polishing pad eventually has to be replaced. It can only be rinsed out so much. I’ve been looking for a polishing pad that lasts as long as the coarse ones. The blue fine pad is a dream come true. If you’re looking for a reusable polishing pad, this is it. If blue requires more rinsing than you are able to do, go green. 💚

I got the medium coarse to go in between my coarse pad and filter floss and it works great, my filter floss isn't getting as nasty as fast and stays
cleaner for longer.

I wanted something better for my Tidal filter & man this thing was worth the money!! The original Blue sponge it came with is half the size of this Green optimizing pad!!

These are an awesome product! You get so much foam, it's a very generous package, that if you are an average hobbyist these sponges will last a long time. I was able to customize all 5 of my HOB with plenty to spare. So much better than what comes standard with them and they are a WAY cheaper than rebuying the filters that the companies want you to buy. This combined with biological filter media and you are set. Pairs well with the filter floss they sell too.

The size and price .the customizing is a great thing . I like how Aquarium Co-Op thinks about how to make things better , keeping products reasonably priced also helps
Thank you for all the great now products you make.

I converted to using these large porosity filtersinstead of the prefab filter set. So much more economical and sustainable as well because they are reusable. I wish I had know sooner.

I appreciate the style of it and it’s better than the stuff from other filters

This is a replacement for a biological filter that came in one of my hang-on-back filters. I love using the coarse or medium sponge pads as they are easy to put in, easy to squeeze-rinse in aquarium water, and put back. I was having issues with the ceramic rings, especially with rinsing and replacing them after a planaria outbreak. Was due for some new filter pads.

Great. I used them to replace old filter media in different types of filters. Canister to corner.

These pads are great for Matten or even just inside the hob or canister filter! Will buy again.

The Filter Optomizing Pad(s) have worked great for my fish needs, extra protection for water quality.

Great product, I do recommend the product.

can't beat the price or the quality of these filter pads!

These pads are great for DIY people like me. Just make sure you measure twice and cut once! lol

Great service and all types of aquarium products.

Seems like a high quality sponge pad.

Easy to use and cut to your specific needs. Works great.

Nick work guys

Purchased the medium pad and installed it in 3 filters so far. The pad is easy to cut and seems dense enough to perform proper filtration. Will continue to monitor them. So far they seem to do a good job.

Always the best products and customer service!!

As always, wonderful shipping time.

Just set up a 21.4 Tideline cube and was able to stuff two sections of the back filter chambers with pieces of the medium green foam, both as extra physical filtration and to prepare as media in case I ever need to set up a quarantine tank. Looking forward to using the ammonia filter pad in my order too, as a second line of defense when I’m vacation and my friends inevitably overfeed. May consider getting the blue fine pad, wish you offered a smaller/half size!

I have used the fine and medium sponge pads. I cut them to shape for my Tidal 110s. They do a good job of trapping stuff. Happy!

I'm really loving these filter pads! They are easy to cut and make better replacements for the standard foam that comes with certain filters. I appreciate that these come in 3 different porosity options so you can stack your filters for optimal filtration. As we all know, sponges make the best filter media!

Great experience

Love the quality

All products ship quickly!

Works great paired with coarse sponge, and I haven’t had any problems with bypass like I had with coarse sponge and fine floss. I did have to butcher it with scissors to reduce thickness by half. The thickness of this product would not allow me to fit any other media into the HOB.
