Seasonal care is made twice a year: in the spring and autumn. In the spring, for example, you need to reduce the power of heaters and artificial lighting. It is worth cleaning the aquarium thoroughly and remove yellowed plants from it. And also rinse all technical devices. Autumn you have to transfer the aquarium back to the winter mode. Increase lighting and heating power. Check the serviceability of the thermostat and compressor. Also check the condition of the feed that is divorced at home. Now you are ready for a long winter. And your pets will delight you with cold long evenings.
