Hello. I've rescaped my 6x2x3 tall and added a large school of jumbo neon tetras and cory cats. Over the last week I've found over a dozen in the sump. Does anyone have experience in zip tying gutter guard or even a larger screen material on the weirs to prevent this. I have a low flow setup and would plan on leaving the very top open to prevent any overflow should something catastrophic happen. I'm also open to any other ideas. Thanks in advance.
