This calculator gives a planning range, not a quote. Local prices, brands, shipping, and used equipment can change the final number.

What it includes

Tank, light, filtration, substrate, hardscape, plants, fertilizer, tools, CO2, livestock, and early maintenance items.

Best use case

Planning a new freshwater planted tank before you buy equipment, especially 45 cm, 60 cm, 90 cm, and larger display tanks.

How to plan a planted aquarium budget

A planted aquarium is usually more expensive than the glass tank suggests. The major cost drivers are lighting, filtration, substrate, CO2, hardscape material, and the amount of healthy plant mass used at startup.

For a low-tech tank, you can avoid pressurized CO2 and use slower plants, but you still need stable light, good circulation, and a realistic maintenance schedule. For demanding stem plants, carpeting plants, Dutch layouts, or rare species, pressurized CO2 and stronger lighting become part of the system rather than optional upgrades.

The safest budget plan is to buy fewer decorative extras and spend properly on the core system: light, filter, substrate, CO2 stability, and plant mass. A tank started with too few plants often spends the saved money later on algae fixes, livestock losses, and repeated rescapes.

Frequently asked questions

Is CO2 required for a planted tank?

No. Low-tech tanks can work without pressurized CO2, but plant selection and lighting need to be more conservative. For carpeting plants, dense stem plants, and rare species, CO2 usually improves stability.

Why is substrate included in the estimate?

Active soil, base fertilizer, sand caps, and replacement substrate can be a major startup cost. They also affect early water chemistry and plant rooting.

Can I use second-hand equipment?

Yes, especially tanks, stands, tools, regulators, and filters. Check seals, scratches, leaks, regulator safety, and filter noise before trusting used gear.

How accurate is the result?

The estimate is intended for planning. Real prices vary by region, brand, shipping, livestock availability, and whether you buy new or used equipment.
