The Boyu EC series is a complete glass aquarium — tank, hood, LED lighting and a built-in top bio filter in one unit. It is aimed at someone setting up a first tank who does not want to specify a filter, a light and a lid separately, and it covers the two sizes most first tanks land on.
The EC-400 holds 33 litres and measures 38.2 x 26.1 x 45cm, with a 5W LED and a 290 L/h top filter supplied with media. The EC-600 holds 66 litres. Neither includes a heater, so budget for one if you are keeping tropicals. A 33L tank is small for goldfish specifically — goldfish grow and are heavy waste producers, and the 66L is the more honest starting point for them.
Specifications
- EC-400 — 33 litres, 38.2 x 26.1 x 45cm, 5W LED, 290 L/h top bio filter with media included.
- EC-600 — 66 litres, the larger option and the better choice for goldfish or a fuller community.
- Built-in top filter — no separate filter to buy or hang on the back.
- LED hood — integrated lighting and lid in one.
Setup
Rinse substrate and decor before use. Fill, run the filter and cycle the tank before adding fish — a new tank needs several weeks to establish its biological filter, and stocking straight away is the most common cause of early losses. Add a heater separately for tropical species. Do not move a filled tank.
Pair with a Boyu glass or digital thermometer and a gravel cleaner for water changes.
