Aqua One Betta Duo Aquarium Spares

Aqua One Betta Duo Aquarium

The 20 litre Aqua One Betta Duo Aquarium is designed to accommodate two Siamese fighters (Betta) in their own luxury compartments.

A 25w Aqua One Nano heater should be added to the rear compartment to keep the aquarium warm (Bettas are from South East Asia). The heater will fit next to the pump.

We suggest changing the Aqua One 1c Carbon Cartridge every month and changing 25% of the tank’s volume every two to three weeks. Replace the Aqua One 102c ceramic cartridge every three to six months or so and treat the filter pump to a new impeller once per year to ensure continuous performance.

The Aqua One 113s sponge insert will last around a year before replacement becomes necessary. Please note that the acrylic cover clips are easily broken but easily replaced too – we usually have hundreds of packs in stock.
