If you plan to be away for longer then 14 days then you’ll need a far more sophisticated filtration system including several filter systems.

Container size

If investing in a filtration system is not an option then moving to a more substantial container may be an alternative solution, with a more substantial container comes a more substantial body of water, meaning the water will need much longer to be toxic because to overfeeding, as well as minimize the chance of the container evaporating and becoming dry because of heat.
