Have Questions About Freshwater Accessories?
We Have Answers.

Get quick answers to common questions about Freshwater Accessories

What are essential accessories for a freshwater aquarium?

Essential accessories include airline tubing, air stones for oxygenation, nets for safe fish transfers, feeding tools like auto feeders, thermometers, suction cups for securing equipment, breeding boxes for fry protection, and backup air pumps. These items help keep your aquarium running smoothly and make care tasks easier.

Do I really need an air stone in my tank?

While not mandatory for every setup, air stones help improve oxygen exchange and water circulation. They are especially beneficial in tanks with higher bio-loads, warmer temperatures, or limited surface agitation. Air stones also create a pleasing visual effect with streams of fine bubbles rising through the water.

What is the purpose of a breeding box?

A breeding box provides a safe, separated space for fish fry, livebearers like guppies, or injured fish needing isolation. It allows water from the main tank to circulate without exposing delicate fry to adult fish that may predate them.

How can accessories make maintenance easier?

Accessories like airline tubing kits, suction cups, or surface skimmers streamline tank maintenance by improving equipment placement, boosting oxygen levels, or removing floating debris. Automatic feeders and light timers automate feeding and lighting schedules, helping maintain consistent conditions with less daily input.

Are all aquarium accessories safe for fish?

Only buy accessories labeled as aquarium-safe or made specifically for aquariums. Avoid items that may rust, leach toxins, or have sharp edges. Charterhouse Aquatics carefully selects all accessories to ensure they are fish-safe, durable, and functional.

How often should I replace or clean accessories?

Soft tubing, air stones, and nets should be checked every few months. Replace tubing that stiffens or cracks, swap air stones if bubble output decreases, and disinfect nets regularly to avoid spreading disease. Most durable items like thermometers and suction cups last a year or longer with proper care.
