Budget Setup

55 Gallon Planted Tank — Low-Tech Budget Path

A 55 gallon planted community tank on a real budget. The core essentials (~$295) cover glass, capable filtration, LED, heater, sand, and easy plants — with CO₂ called out as a later upgrade, not a fake “all-in under $300” claim.

What NOT to buy

  • Undersized “10G HOB” on a 55G.
  • Carpets + no CO₂ + weak light.
  • Instant heavy stocking.

Common mistakes

  • Skipping quarantine mindset.
  • Lights too long.
  • Buying CO₂ without a drop checker.

Why this shopping list

55G is a community sweet spot. Keep biology honest with the stocking calculator, then graduate to CO₂ or high-tech when ready.

What fits this setup

  • After cycle: classic community mix sized to calculator.
  • Avoid: large aggressive cichlids in a “planted show” plan.

Week-1 checklist

  1. Day 0 Build & start filtration

    Rinse substrate. Fill with dechlorinated water. Start filter/heater as listed.

  2. Day 0–1 Seed bacteria & short lights

    Add bottled bacteria. Run lights 6–7 hours.

  3. Day 2–5 Observe — limited livestock

    Spot-clean. Do not overfeed. Watch cloudiness.

  4. Day 5–7 Test if you can

    Check ammonia/nitrite. Small water change if needed.

  5. 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

Can I do CO₂ under $300 on 55G?

Usually not with quality gear — core here is low-tech; CO₂ is optional upgrade.

HOB vs canister?

Strong HOB works; canister is comfort/upgrade.

How long to cycle?

Often 2–6 weeks — test, don’t guess.
