Seasonal Care: Adjusting Your Live Feed Systems Through the Year

A UK home doesn't hold a steady temperature all year round, even with a heater running. Here's what actually needs adjusting as the seasons turn.

Winter: Heating Load and Draughts

A heater set correctly in August can be working much harder — and less effectively — by January if a tank sits near a draughty window or an unheated room. Check your heater is actually holding the set temperature during the coldest snaps, not just assuming it is because it was fine in summer. Rooms that go unheated overnight are the usual culprit for a tank that reads fine in the evening but has drifted by morning.

Culture tubs kept without a heater (microworm, vinegar eels) will also slow down noticeably once room temperature drops — this is normal and not a sign of a failing culture, but it does mean planning for a slower harvest rate through the coldest months rather than being caught short.

Summer: The Overlooked Risk

It's easy to think of a heater as the only piece of temperature-control kit that matters, but a genuinely hot UK summer can push an unheated or under-ventilated room well above safe range — conservatories and south-facing rooms are the classic problem spots. Warmer water also holds less dissolved oxygen, so a heatwave is exactly the wrong time to also skip water changes or let filter flow drop.

Feeding Rate Follows Temperature

Metabolism in snails and shrimp is directly tied to temperature — a colder tank means slower feeding, slower waste production, and slower breeding, all at once. Feeding a winter tank at the same rate as a summer one is a common way to end up with uneaten food fouling the water, since it's not being consumed at the rate it was a few months earlier. Scale feeding down as temperatures drop, and back up again as they recover — not on a fixed schedule regardless of the season.

The Underlying Principle

None of this is about chasing perfect numbers year-round — it's about recognising that "normal" for your system shifts with the season, and checking in rather than assuming a setup that worked in one month still works unchanged in another. Our Temperature, Heating & Thermal Shock guide covers the fundamentals in more depth, and our general Tank Health & Maintenance guide is a good routine to build seasonal checks into.

• —  Check heaters are actually holding temperature during the coldest overnight periods, not just in the evening
• —  A hot summer is a genuine risk too — watch for overheating and dropped oxygen levels
• —  Scale feeding to temperature — colder tanks need less food, not the same amount
• —  Unheated culture tubs slow down in winter — that's normal, plan around it
