Question cooling down 45L water tank as cold as possible? (for no more than $200)

Hi,

what is an economical way to cool water in a 45L tank? i want the water to be as cold as possible. now the water temperature is 35c.

- if i get a cheap water cooler like this one: https://ae01.alicdn.com/kf/HTB1BiiVO...9q6xyypXai.jpg
, then connect the cold outlet to the tank and put a water pump in the tank and send it back to the water cooler? if yes, can you help explain it?

- or, these cheap aquarium coolers https://www.aliexpress.com/item/4000462429723.html, are they useful? how low can they get the water down, if it is 35c ?

- another way?

Little deep feezers can be found cheap on c r a i g s l i s t or similar. Really depends on how cold you want it... If you want it frozen, get one big enough to put the 45l container in. Otherwise, plumb it through the freezer.

Perhaps the more important question is how much lower than room temperature you need to go. Things like room air conditioners will provide a certain amount of temperature drop and that is also true of many of the cooling items we might use for the tank.
A cooling fan system can make a good difference in the tem but not if the room and humidity are too high. So how many degrees do you feel you need to drop?

what kind of room is it going to be kept in? if everything around it is too hot then you're going to end up burning out the cooling system.
