How to Choose Koi? A Guide to Finding the Right Water Temperature for Them
There are two main categories of temperature control equipment: heating equipment and cooling equipment. (1) Heaters. There are two types of electric heaters: one is an ordinary electric heating tube, and the other is an automatic temperature-control electric heater.

(1) Heaters There are two types of electric heaters: one is an ordinary electric heating tube, and the other is an automatic temperature-control electric heater. The latter can effectively regulate water temperature automatically, but its price is relatively high.
At present, keepingkoimostly uses automatic-control electric heaters.

(2) Bottom heating cable: It is placed under theaquarium's substrate sand and can slowly release heat energy, promoting hot-and-cold exchange in the water at the bottom layer. As hot water rises and cold water sinks, a convection cycle forms, breaking the temperature layers and making the water temperature in the aquarium uniform.
Bottom heating cables are generally used in aquariums of 90 cm or more. Laying them along the bottom can achieve an excellent temperature control effect, but their price is relatively high.
(3) Automatic temperature controller : It is the hub for regulating temperature. As the temperature rises or falls, it can automatically cut off or connect the current to ensure a constant temperature. Its shape is like a glass test tube, and it hangs on the upper part of the aquarium.
At present, there are also many electronic regulators on the market that use microcomputer control systems to regulate temperature.

(4) Cooler: For koi in an aquarium, excessively high temperatures can likewise affect their normal metabolism and various functions, causing disease or death. Therefore, in hot summers, installing a cooler in the aquarium to lower the temperature and maintain a balanced and stable suitable
water temperature is equally necessary. Most products currently sold on the market are powder-box designs that combine a heater and a cooler.
