Poly (methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others (see below).
However, total elimination of algae is considered unlikely in a hobby aquarium. Algae can be used as an bioindicator to inform an aquarist on water chemistry and other conditions. [2] Some species are intentionally cultivated within algae scrubbers. Few algae, such as marimo or red moss, are sought after for aquascaping in freshwater aquaria.
Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms. [ 1 ]
A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass. [2] Water-absorbing polymers, which are classified as hydrogels when mixed, [3] absorb aqueous solutions through hydrogen bonding with ...
Appearance. Shark Tunnel at the Georgia Aquarium. A shark tunnel (or aquarium tunnel, acrylic tunnel and exhibit tunnel) is an underwater tunnel that passes through an aquarium, typically with sharks and related aquatic life. They are usually made of thick acrylic glass.
Plastic Bottles Can Leach Microplastics. Roughly 10% to 78% of bottled water samples contain contaminants, including microplastics. These are often hormone (endocrine) disruptors, and they're not ...
The swim bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth without having to waste energy in swimming. [1] A fish with swim bladder disorder can float nose down tail up, or can float to the top or sink to the bottom of the aquarium.
