7” it’s in a 75 that now has a Eheim 2217, 2 Aquaclear 110’s, and a large sponge filter. And I still vac twice a week.That’s INSANE lol. How big is yours? I’ve got really good flow but that’s worse than the royal and blue eye put together!
I’m so glad mine don’t have that kind of appetites. I’d estimate my royal at 5” and my blue eye is 12”7” it’s in a 75 that now has a Eheim 2217, 2 Aquaclear 110’s, and a large sponge filter. And I still vac twice a week.
