About this part

This is our original fine-mesh overflow cover, the one shrimp keepers have recommended to each other for years. It snaps over your tank's built-in overflow slots or intake grill and keeps shrimp, shrimp fry and betta fins out of the filter chamber, without cutting your normal flow.

Find your tank in the choices. Each choice is made for the overflow slots of that tank model. The price is for one cover unless the choice says pair or set.

Compatibility
  • Fits: the original Fluval Flex 9 and 15 gallon, the Fluval Spec V 5 gallon and Spec III 2.6, the Imagitarium 3.7, and many all-in-one tanks: JBJ, Innovative Marine, Coralife BioCube, Fiji Cube, Seachem Tidal, Waterbox, Lifegard and more.
  • Does not fit: the Fluval Flex 2.0. Its fine-mesh cover pair is a separate product.
Why it helps
  • Fine mesh keeps shrimp, fry and fins on the display side.
  • Snap-in install: no tools, no glue, no suction cups.
  • Low profile, so it disappears against the tank trim.
  • Fluval choices come in black or white.
Installation
  1. Pick your tank model.
  2. Line the cover up with the overflow slots.
  3. Press until it snaps in.
In the box

The first intake cover I ordered was a tiny bit short (I don’t think it was Adam’s fault, I think they revamped the UNS AIO 40A at some point), and he sent me a replacement that fits like a dream. Excellent customer service. Highly recommend this shop.

Seller was very responsive. When the original piece didn’t exactly fit my UNS A40 tank, a second one was sent and it fit perfectly. I thought I didn’t need to measure since the piece said it was for my exact model. I would recommend measuring and confirm with seller before ordering. The second piece we also went with skinny slates vs a bunch of tiny holes. The tiny holes were not allowing enough water into the filter and that section was getting low water levels. The second piece sent was perfect and allows water through easily, but catches little leaves and should be narrow enough to keep small fry out of the filter section (a big general risk with that tank model if using it for breeding or very small nano fish). Very pleased with my purchase!

nice thought of making the item. but the holes are so small like pinholes. what animal something needs a hole that small? my tank almost flooded my living room 5 min after I put them in. luckily my ATO auto shutoff and I was able to turn off return pump in time. I ended up drilling out 6/94 inch holes. I probably could have gone larger easy, like 1/4. i do not get the logic of the pinhole size openings. if seller updates to a design with larger holes I will buy again, since now mine have a bunch of plastic burrs.

I wish I knew about these when I had my guppy fry but now I can no longer worry about my shrimp and snails getting sucked up into the overflow. The water flow does slow down which is something I didn't think of but it's not too big of an issue so far. Shipping was fast and I got 2 for the price of 1! Thank you!

This is one of the worst designs I’ve seen on the market. Please make sure your products are properly tested before releasing them for sale.

This screen is an excellent fit and keeps my fry from going into the overflow. The only drawback for me is that it slows my overflow to the point that the return pump will run dry/suck air. This may only be exclusive to me and my setup. My work around was to enlarge some of the holes to match the flow. I bought 2 and do not regret it.

Works great and keeps my shrimp from accessing the back chambers on the Fluval Flex 15 gallon aquarium.

These guards are perfect! I set my new top fin 3 gallon tank and put some tiny shrimp in it. Within minutes, I watched in horror, one get sucked up into the intake. I was sad thinking I couldn't put shrimp in my tank until I found this company on Etsy. Thank you so much for these two small pieces that make it possible for me to be able to have shrimp in my tiny tank, especially when the tank isn't really big enough for anything else.

I ordered for my biocube16 and the top cover didn’t fit at first. But the seller was absolutely outstanding and sent me a new filter cover that was cut and fit perfectly. I would absolutely recommend. These work so well and keep all my beautiful shrimp protected.

Had to do a little bit of shaving on the back to get it flush with the panel. Other than that works great especially if you have a shrimp tank so the shrimp can’t pass into the filter area

Arrived well packaged. Fit perfectly and easy to install. Exactly what I needed for my blue dream shrimp fry that I raise in a 15 gallon Fluval Flex.
