Frequently Asked Questions
Should I use actual water volume or tank size?
Use actual water volume, which is typically 10-15% less than the rated tank size due to substrate, rocks, and decorations.
Can I overdose aquarium medication?
Yes, overdosing can stress or kill fish and beneficial bacteria. Always measure carefully and follow dosing instructions.
Should I remove activated carbon during treatment?
Yes, activated carbon absorbs most medications and reduces their effectiveness. Remove it before treatment and replace it after.
Do I need to treat the whole tank or just sick fish?
For contagious diseases like ich, treat the entire tank. For localized issues, a quarantine tank may be better.
