DIY aquarium enthusiasts, this one's for you!

These pre-cut, rounded bio sponge pads are designed specifically to fit inside a standard 5-gallon bucket, turning it into a powerful custom filter.

The set includes pads with three different pore densities (20, 35, and 50 PPI - pores per inch), allowing you to layer them for mechanical and biological filtration.

The 20 PPI is coarse for catching big debris, the 35 PPI is medium, and the 50 PPI is fine for polishing water.

Each pad is 11x11 inches with rounded corners to fit snugly in the bucket without dead spots.

The sponge material is super porous, giving beneficial bacteria tons of surface area to colonize and break down harmful ammonia and nitrites.

Perfect for small ponds, turtle tanks, sump filters, or as a pre-filter for larger systems.

You'll need to drill holes for water flow and connect a pump, but that's part of the fun.

It's a cost-effective way to build a high-capacity filter exactly how you want it.

Great for betta tanks, hospital tanks, or breeding setups where water quality is crucial.

If you enjoy tinkering and customizing your aquarium gear, these pads are a fantastic building block.

Get creative and build the filter of your dreams!
