20 Fishkeeping Questions Every Aquarist MUST Pass (Or Stop Keeping Fish!)
Most people shouldn’t own fish.
They buy a bowl, throw in a goldfish, and wonder why it dies in a week. But you? You call yourself an aquascaper.
Let’s test that.
This is not entertainment. This is ecosystem management.
Score under 15? You are harming your tank.
Q1: In typical Indian municipal water (KH 5–8 dKH, pH 7.5–8.2), what is the safest way to drop pH to 6.6–6.8?
A) Use “pH Down” chemicals
B) Use Driftwood & CO₂ injection
C) Use RO water only
Correct: B
Stable acidification requires natural buffering via CO₂ and tannins.
👉 Use proper CO₂ support:

Q2: Why is chasing pH meaningless without knowing KH?
Because KH buffers pH. High KH resists change. Zero KH causes crashes.
👉 Test and stabilize water before adjustments:

Better digestion = better water stability.
Q3: True or False — “0 Ammonia, 0 Nitrite, 0 Nitrate” is perfect.
False.
Plants require 10–20 ppm nitrate for proper growth.
👉 Feed balanced nutrition to support plant-fish balance:

Q4: GH vs KH : What’s the difference?
GH = Calcium & Magnesium
KH = Carbonate buffer
Both are essential.
👉 Stable diet reduces mineral imbalance stress:

Q5: Why is pure RO water lethal?
TDS 0 causes osmotic shock. Fish require minerals.
👉 Support stressed fish with:

Q6: What happens if you restart a canister after 8 hours off?
Anaerobic toxins get pumped back into your tank.
👉 Support recovery with immune-boosting feed:

Q7: Is the UV steriliser a cure for BBA or Green Spot?
No. Fix flow and CO₂.
👉 Reduce waste buildup with high-digestibility food:

Q8: Why is “1 inch per gallon” a lie?
Bioload matters, not length.
👉 Lower bioload through cleaner digestion:

Q9: Why are bio-balls inferior to sintered media?
Surface area = bacterial colony strength.
👉 Pair strong filtration with clean feeding:

Q10: Should you wash filter media under tap water?
False. Chlorine kills bacteria.
👉 Reduce clogging by feeding cleaner food:

Q11: Why do stem plants melt at the bottom?
Poor flow. CO₂ not reaching lower levels.
👉 Strong nutrition supports overall ecosystem balance:

Q12: Root tabs vs liquid fertilizers — interchangeable?
No. Different feeding strategies.
👉 Healthy fish waste = better nutrient cycling:

Q17: What is Old Tank Syndrome?
KH depletion + nitrate buildup + sudden water change shock.
👉 Maintain balanced feeding to reduce nitrate spikes:

Q18: Why is fishless cycling better?
Ethics + stronger bacterial colony.
👉 Support new tanks safely:

Q19: #1 cause of algae in new tanks?
Ammonia spikes + high light.
👉 Reduce ammonia production with cleaner food:

Q20: Why recommend insect-based food over cheap flakes?
Because corn & wheat fillers pollute water and cause bloating.
👉 Upgrade to clean, digestible nutrition:

Fishkeeping is not decoration.
It is water chemistry, biology, and discipline.
If you scored under 15, don’t buy another fish.
Upgrade your knowledge. Upgrade your equipment. Upgrade your nutrition.
