About this part

Shrimp fry are tiny, and an open intake slot can pull them right into the filter. These shrimp guard prefilter covers close off the Flex 2.0 intake slots and come with 30 PPI coarse sponge already in place. The sponge stops bits of food and plant, and your shrimp get a great place to graze.

Compatibility
  • Fits: the Fluval Flex 2.0, 9 gallon or 15 gallon. Each size is its own set; pick yours.
  • Does not fit: the original Flex 9 and 15. We make separate prefilter covers for those tanks.
Why it helps
  • Closes the intake slots so shrimp fry stay in the tank.
  • 30 PPI sponge comes already loaded.
  • A sponge surface for shrimp to graze on.
  • Upper and lower pieces, each engraved UPPER or LOWER.
  • 9 gallon set about 5.5 in long; 15 gallon set about 6.3 in long.
Installation
  1. Find the lower prefilter: its label says LOWER, and it has one short tab and one long tab.
  2. Turn each prefilter so its broad, engraved side faces the outer glass and its narrow side faces into the tank.
  3. Fit the lower prefilter first. Set the long tab in the bottom slot of the overflow and slide the prefilter toward the glass until the tab is seated.
  4. Press the short tab into the slot above, with a light downward push on the top end, until it clicks in and sits flat.
  5. Fit the upper prefilter above it the same way. Gentle pressure is all it takes; never force a tab.
In the box

One set: an upper and a lower prefilter cover with sponge, for the size you pick, in black or white.

Designed and 3D printed in Pennsylvania. One flat shipping price covers your whole US order, so a second part ships for no extra cost.

Great Product and Great Experience

It doesn’t snap on very well, and I’m not able to use it as my substrate goes up too far to put the lower piece in. Something like this isn’t practical if you have a high substrate in the back of your tank..

Finally! An intake guard that actually fits. I have tried multiple intake covers from different seller’s and they either had a poor fit or they were made of bad quality. This one is good. Thank you for making this product.
