Ornament Divers Helmet Med 7.5×10.5h — Medium diver’s helmet ornament for nautical-themed coldwater and tropical tanks
The old brass diving helmet is one of the classic aquarium themes, a single piece that tells the story of a sunken wreck without filling the tank with clutter. Ornament Divers Helmet Med 7.5×10.5h (SKU: 36123) is the medium Divers Helmet from Aqua One’s ornament range, about 7.5 cm across and 10.5 cm high. Aqua One describes its ornaments as adding life and colour to the aquarium and creating an aesthetically pleasing environment for the aquarium and its inhabitants, and it rates the Divers Helmet for coldwater and tropical aquariums. It is one of the pieces Aqua One shows in its 360-degree ornament viewer, so buyers can turn it round on the maker’s site before choosing.
The medium is the larger of the two sizes: a small Divers Helmet (36124) measures 4.5 × 6 cm for nano tanks and bowls, while this 10.5 cm piece suits tanks of roughly 40 to 60 cm, where it can stand in the foreground or tuck in against rockwork. A helmet sits well with other nautical pieces such as treasure chests, anchors and shipwreck sections, or on its own on a sandy patch of substrate. Aqua One’s range covers many designs, so the helmet can be grouped with others in the same theme; note that the maker also lists a separate Deep Sea Diver’s Helmet under code 24402, so check the code when matching an existing piece. As with any decoration, rinse it in plain water before it goes in and clean off algae with a soft brush during water changes, never with soap, detergent or household cleaners.
