@Erica-Renee I have the 3k also and it’s amazing. I don’t suggest you read the instructions lol they are pretty vague. It’s easy to set up, but trying to figure out the modes was not easy with its instructions. It was easier to watch the you tube video lol. But packaged very well, and it was easy to set up. The safety screens that came with mine were way way way too small. So I left mine off, and when you go to adjust it, make sure you hold the center then adjust it. The gyre ends will come off. Love to see pics of them in your tank .
