Common questions
Is this a substitute for a veterinarian or aquatic specialist?
No. Product suggestions reflect common, widely-used options for the issue described, not a professional diagnosis.
Do you get paid for these recommendations?
Yes. We're an Amazon Associate and earn a commission on qualifying purchases. See our disclosure for details.
How accurate is this?
It matches your answers to the most common cause for that combination of symptoms. Aquariums are full of edge cases, so treat this as a strong starting point, not a certainty.
Why only freshwater tanks?
Saltwater and pond setups have different common issues and products. We'd rather cover freshwater well than everything shallowly.
What if my symptoms don't match any answer?
Several paths include a "not sure / something else" option that asks a follow-up question to narrow it down further.
