Innovative Marine NUVO Fusion 20

89%of 19 owners recommend

89% recommend · 6% neutral · 5% don't

Owners praise

Leak-free durability over years of use, owners report tanks running 2+ years, changing hands through multiple owners, with no sagging, fatigue, or leaking
Strong build quality and value for the price, including the bundled/included equipment
All-in-one design hides heaters, filters, and skimmers in the rear sump so wires and equipment stay out of the display, unlike open tanks

Owners complain about

Rear pump chamber design lets the return pump run dry if evaporation isn't topped off regularly, and some owners find the stock return pump low quality and swap it out (e.g., for an Eheim Compact 1000)
