One of the most common issues we see? Fish that simply shouldn't be living together 😬

Before adding anything new, ask: same water requirements? Similar temperament? Enough tank space for both? A peaceful community can unravel fast — aggressive feeders outcompete shy ones, fin nippers stress long-finned species, and territorial fish claim the whole tank.

Our team at the trade counter are always happy to help you plan a compatible community before you buy. Worth a quick chat before you commit.

Quick tip that catches a lot of people out 👆

When it's time to clean your filter, always rinse the media in a bucket of old tank water — never tap water straight from the tap.

Tap water contains chlorine and chloramine, which will kill the beneficial bacteria living in your filter. That's the bacteria that breaks down ammonia and keeps your water safe. Losing it causes a mini re-cycle and can crash your water quality fast.

Gently squeeze sponges in old tank water, and if you're swapping out media, do it gradually rather than all at once. Simple habit, massive difference. 👍

As temperatures rise, your pond needs a little more attention 🌞

Warmer water holds less oxygen — which means your koi and goldfish are working harder to breathe. Keep your pump running continuously, consider adding extra aeration, and make sure your UV and filter are performing at their best.

Now is also the perfect time to check your UV lamp. Most need replacing annually, and summer is when they work hardest against algae blooms.

Hot weather is on the way — and your aquarium feels it too ☀️

When room temperatures rise, so does your tank water. For tropical fish that means stress and reduced oxygen. For corals and marine setups, even a degree or two above the safe range can cause bleaching and livestock losses.

The fix depends on your setup:

Cooling fans — the affordable first line of defence for most freshwater and tropical tanks. DYMAX fans from £15.99 and TMC fans from £34.99 clip straight on and drop temps by a few degrees with minimal fuss.

Aquarium chillers — for reef keepers where precise temperature control isn't optional. Hailea chillers from £279.95 cover most home setups. For larger or more serious systems, the Teco TK range (£721 to £1,338) offers chiller/heater combos that maintain the perfect temperature year round — no separate heater needed.

Whatever your setup, we've got the solution. Browse the full range here 👇
