AQUANEAT Pre-Filter Sponge – 6 Pack (0.8” Intake Cover for Shrimp, Fry, Snails)

The AQUANEAT Pre-Filter Sponge is a simple but essential accessory for aquariums with shrimp, baby fish, or snails. Placed over the intake tube of a filter (HOB, canister, or powerhead), it prevents small livestock from being sucked into the filter while still allowing strong water flow.

Made of durable foam, the sponge also acts as an extra layer of mechanical and biological filtration—trapping food particles, plant debris, and waste before they reach your filter media. This keeps your main filter cleaner and extends the life of cartridges or biological media.

This pack includes 6 sponges (size: 1.8”D x 3.2”H, 0.8” intake), making it a budget-friendly option for multiple tanks or replacements. The sponges arrive vacuum-packed; simply rinse and they expand to their full shape. They are easy to clean and can be reused many times.

👉 In short: an affordable, reusable add-on that protects shrimp and fry while boosting your filter’s performance.
