My cichlids haven't cracked a single heater since I snapped this guard on—the plastic feels sturdy enough to take a knock from a rock or a tail. Fits my 2.4cm glass tight, and it's nice not worrying about shards in the tank anymore.

Alexander ★★★★★ Oct 20, 2026

My heater sits right where my cichlids like to dig, so this guard has been a lifesaver for preventing cracked glass. The plastic feels sturdy and the 2.4cm opening fits my older heater perfectly, even though it's a different brand.

Fits snugly over my heater's glass tube without any wobble, and the plastic feels sturdy enough to handle a curious pleco bumping into it. Installation was a breeze and it doesn't block the temperature reading at all.
