Fluval Edge Heater Cover
The Fluval Edge Heater Cover is designed specifically for the glass-and-stylized Fluval Edge aquariums, offering a low-profile protective shroud that preserves the tank's aesthetics while preventing fish contact with heater elements. It holds a best-in-class spot for small-tank applications because it balances design integration and affordability better than heavier-duty cages like the EHEIM, though it is less universal than EHEIM and lacks the inline capability of Hydor's kit.
