Specific product picks
What NOT to buy
- Undersized kit HOBs meant for 20–40G.
- Carpets + weak light + no CO₂ on day one.
- Instant heavy stocking on a fresh 75G.
Common mistakes
- Buying a stand that can’t carry wet weight.
- Lights 10+ hours empty.
- Skipping heater because “room is warm”.
Why this shopping list
75G is a true community canvas. Keep biology honest with the stocking calculator, then graduate to high-tech $200–500 gear when you want soil + CO₂.
What fits this setup
- After cycle: classic community sized to calculator — not a “pet-store wall” dump.
- Avoid: oversized cichlids that uproot everything.

-
Day 5–7
Test if you can
Check ammonia/nitrite. Small water change if needed.
-
Week 2+
Stock when 0/0
Drip-acclimate. Stock slowly.
Spend-next upgrades
- Test kit — Cycle confidence (~$25–35)
- Better light / CO₂ — Next tier quality (Varies)
- More plants — Beat algae with mass (~$20–40)
FAQ
Is $500 enough for a planted 75G?
For a low-tech core (~$485) yes. Full high-tech soil+CO₂ usually needs a second cart.
Canister required?
Strongly preferred at this volume; dual HOB is a budget workaround.
When to add CO₂?
After plants/light are stable — see high-tech / CO₂ lists.
