When Something Looks Off

Test the Water. Then Support the Tank.

Use these two paths when livestock looks stressed or the tank feels unstable: check the water first, then choose support for shrimp, fish and biological filtration.

Test Your Water First

Before adding treatments, test your water. Ammonia, nitrite, GH/KH, TDS and pH changes can quickly affect fish and shrimp health.

Fish or Shrimp Look Stressed?

Start with the basics: temperature, water quality, oxygen and biological filtration. Check the cause before choosing support.

Winter Tank FAQ

Check First. Support Carefully.

Simple answers for colder days, changing water conditions and new indoor setups.

When should I check my aquarium heater?

Check the actual water temperature when colder weather starts, after a cold night, or whenever fish or shrimp seem less active. Use a thermometer to confirm the heater is working and avoid sudden temperature changes.

Should I add treatment straight away if fish or shrimp look stressed?

Start by checking temperature, water quality, oxygen and filtration. Test before adding treatments so you can choose support products based on the likely cause instead of guessing.

Which water parameters should I test first?

Start with ammonia and nitrite when livestock look unwell or the tank is new. GH, KH and TDS are also useful for shrimp and planted tanks. Choose support products based on the results.

How can I keep my tank stable during winter?

Keep filtration and aeration consistent, feed gently, remove waste regularly and avoid sudden changes. A steady routine supports a more stable aquarium through colder weeks.

What do I need for a new indoor winter setup?

Start with a suitable tank, heater, thermometer, conditioner, bacteria support, test kit and gentle filtration. Add lighting, plants and food based on the type of aquarium you want to build.
