Boyu makes aquarium hardware — complete glass tanks, filtration, air pumps and the everyday accessories a tank needs. The range covers the practical end of fishkeeping rather than the display end: it is what you buy to get a tank running and keep it running, at prices that make a second or third tank realistic.
The line-up splits into EC Series aquariums (33L and 66L complete units with a built-in top filter and LED hood), filtration (internal filters, the SP submersible series, air-driven sponge filters and activated carbon), air pumps, nets and breeders, thermometers, artificial plants and tank maintenance tools.
Sizing a filter — aim for turnover of four to six times your tank volume per hour, and err upward for goldfish and cichlids, which produce far more waste than community tropicals. Fine-finned fish such as bettas and fancy goldfish struggle in strong flow, so size down or baffle the outlet for those. A sponge filter is the right choice for fry and shrimp tanks, because it has no intake that can draw them in.
What the tanks do not include — the EC Series comes with a filter, media and lighting, but no heater. Budget separately for one if you are keeping tropical species, and cycle any new tank for several weeks before stocking it.
