When choosing an aquarium water pump for your set-up, you will need to have an idea about what flow rate you need:

It should be quiet, shouldn’t leak of course, and be reliable. After all, these outlays aren’t cheap… JBL makes some excellent external filters with thoughtful designs, excellent media options and interesting add-on bits like a surface skimmer.

For tropical fish, you can accommodate more fish per litre: the ratio is 1 litre per 1cm of fish. So, you could safely hold two 10cm fish, three 5cm fish and five 3cm fish safely in a 50 litre tank.

I know why they’ve done it — meaning instant prime — and it has many other useful features like ease of filter maintenance, but the jury is out... Instead give me an Ecco Pro or a standard Professional 3, or, better still, a Professional 3 thermofilter option, and I will surely feel in filtering heaven.

Key Features of Our Diversa Glass Fish Tank: Consider the type of plumbing you have in your aquarium. Some set-ups are quite simple while others have more complex designs using aquarium sumps or external equipment. Whether your aquarium filter system is directly underneath your tank or across the space of a room, you will need to take into consideration the distance the pump will be required to move your aquarium water. The greater the distance, the stringer the flow rate your pump will have to have. As a result, a good rule of thumb is to get a fish tank which has one litre of cold water per 0.5cm (excluding tails and fins) of fish. For instance, a 50 litre tank could safely house two 10cm and one 5cm fish. Or, alternatively, you could accommodate six 4cm fish. You could probably squeeze a couple more in, but this will all vary depending on the types of fish you want to keep, alongside other tank components such as plants, lights and filters. If in doubt, bigger is always better.

You’ll also want some kind of lighting setup for your environment so you can see your new pets night and day. However, bear in mind that lighting is essential for keeping corals in a saltwater tank, as corals have specific requirements for intensity and duration of lighting throughout the day. The same is true of heating systems which tropical fish may need during British winters. Complete Aquatics are pleased to offer all four sizing options available for the Fluval Roma aquarium, including the 90, 125, 200 and 240 ranges, all of which come complete with LED lighting.
