Trojaner im MeerwasseraquariumManche Wirbellose und Algen gelangen unbemerkt in das Riffaquarium und vermehren sich hier stark, so dass die Artenbalance gestrt wird. Sie breiten sich aus, drngen Korallen zurck und schdigen sie. Solche Arten, die sich zu einer Plage entwickeln knnen, nennt Autor Daniel Knop daher in Anlehnung etwa an die Computer Terminologie "Trojaner". Der Aquarianer muss nun eingreifen und steuern, damit die Balance zwischen den gepflegten Wirbellosenarten

I finally got around to cleaning up the cable disaster on my home office desk and these grommets were exactly what I needed. They fit perfectly into the 2-inch holes I drilled, and the plastic feels surprisingly sturdy, not like that cheap, brittle stuff that snaps the moment you try to pop the cover back on. The little brush-like opening is a nice touch because it keeps the cords from sliding back down when they aren't plugged in, and the black finish looks really clean against my wood tabletop. For a 4-pack, the price was a total steal, and it honestly makes the whole setup look way more professional than just having raw holes in the desk. If humans are looking for a quick and cheap way to hide cord clutter, these are a solid bet.

I used this grommet for the entertainment center wall behind my TV and it looks good and works great. Came with all the tools I needed to cut the hole in the wall and install it.
