Is a small aquarium harder to maintain than a large one?

A poorly designed small tank can be challenging, but a properly designed desktop aquarium is very manageable. PNW Custom tanks are specifically built to help maintain stable water conditions, and because the water volume is smaller, maintenance is quicker and more predictable. Many beginners find small tanks easier to stay consistent with long-term than larger systems.

What size aquarium should I choose?

PNW Custom aquariums are specifically engineered for desktop setups, with built-in filtration and carefully selected components to make success easier in smaller volumes. Choose your aquarium size based on your space, goals, and interests:

What comes included with a PNW Custom aquarium kit?

Each PNW Custom aquarium kit includes the core essentials needed to get started: • Display tank • Filtration system or media basket • Return pump • Aquarium light • Evaporation cover or lid • Leveling mat (on applicable models) Everything is selected to work together as a system, so beginners aren’t left guessing or mismatching equipment.

Do I need any additional equipment to get started?

In most cases, you’ll just need a few basic extras: • Saltwater (for saltwater setups) • RODI water • A salinity checker • Livestock, sand, and rock when you’re ready For water, we recommend beginners purchase saltwater and RODI water from their local fish store to keep the process simple in the beginning. Water is inexpensive and lasts a long time for small aquariums. We provide setup guides, videos, and checklists to walk you through every step so you’re never left wondering what comes next.
