That's good to hear. I currently have a 6g fluval edge, so the XL425 will be a significant upgrade for me. I hope I haven't bitten off too much!I got the XL425 too and was my first tank with a sump. Now I wish I had started with sumps and not AIO. I was debating about swapping out my JBJ45 for either a Reefer 170 or 250 or an SCA 50 gallon.
