Just like us, our fish friends feel stressed when it’s extremely hot outside. Here are seven ways you can help them stay cool and calm.
Extreme heat creates problems. When temperatures are high, fish go into metabolic overdrive, consume more oxygen and produce more waste products. These waste products can be more toxic at higher temperatures. Here are some simple tips to use when temperatures are extreme:
- Cool the water
Add ice (which does not contain chlorine) or frozen water bottles to help reduce temperatures for species that need cooler temps. Be careful if you have Marines, as adding frozen fresh water will reduce salinity.
- Maintain oxygen levels
Ensure that tanks are well aerated to maintain oxygen levels (the hotter the water, the less oxygen it can carry). Adding extra air lines will help to increase oxygen exchange. Also check to ensure that filters are working properly, with adequate water flow.
- Check water parameters
Make sure water parameters, such as pH, are correct. Not sure? Visit us in store for a water health check.
- Do not overstock
Be careful not to have too many fish in your tank. Overstocking tanks increases oxygen consumption, which in turn decreases oxygen levels. Overstocking also increases the amount of waste that your filter system has to cope with, which means it may not work as efficiently.
- Frequent water changes
More frequent water changes can help by reducing water temperature (if tap water is colder than the tank) and build-up of toxic metabolites.
- Reduce feeding
This can help cut back the metabolic stress and production of wastes. Obviously resume normal requirements once things cool off again.
- Minimise lighting
Some lights can emit heat that will increase the temperature of your tank even further. On days of extreme heat, turn off your lights (if possible).
