🐟 Efficient NACX Aquarium Fish/Shrimp Mesh Net Filter Guard- Stainless Steel Cover for 12mm/16mm ID Fish Tank Intake Strainer Pre-Filter Review

Good quality screen but sloppy for 15mm blocks. I would like it to be about 3x longer for a high flow setup, but 1 works fine until fully clogged (2x on day one). This is for an outdoor pond, so more for protection from dirt and critters.

I no longer fish shrimp out of the external filter! I didn't know they existed until I accidentally stumbled upon them. I just run the toothbrush over the surface to reopen the holes and I'm done. The downside is that large particles don't get into the canister, but I'd rather do the extra work in an aquarium than with fish or dozens of juveniles. from the layers of the environment.

They are well made but one of the two screens arrived with a large dent. I pulled it out again, but there are creases on the opposite sides. So I can't rotate it so the damage isn't visible from the front of the aquarium. I probably should have returned them but the tank was ready for water and I didn't want to wait. So if you're a perfectionist, you might want to make sure supplies have enough time to send back and timely replacements when they're needed.

Cutting the plastic spacer at the top makes it easier to insert the filter intake tube (quickly learn not to cover the very end of the intake tube). On the first day we cleared the tube of dirt several times. However, on the second day we found out that the fish and snails do the cleaning for us! Now I just stir the water around the substrate every few days. Small particles rise into the water, are caught by the filter fabric and cleaned by the pool residents. Works perfectly! In the meantime…
