29 gallon aquarium equipment plan

The 20-long footprint with a taller water column.

Its length matches the 20-long example, but the extra height changes reach, heater placement and the depth at which plants receive light. Do not transfer a light-performance assumption solely because the fixture spans both tanks.

Manufacturer dimensions and top variants checked 2026-09-07. These match the named Aqueon format, not other brands with the same volume label.

The current top page’s dimensions include folded or packaged measurements, so they are not used as an installed span. Dry-fit the support ledges and rear accessory strip. Confirm the current package matches the listed SKU before fitting the top.

The Aqueon 2025 catalog lists this stand for the named tank format. This is documented compatibility, not a current stock or condition claim. Match the exact part and current assembly/support instructions before purchase. Stand weight is not published in this record and remains blank in the weight worksheet.

Start the weight worksheet with this empty-tank weight. It leaves substrate, decoration, equipment and stand weights unknown.

Complete each equipment job

  • Use the Aqueon tank and lid identifiers below. Match a suitably designed aquarium stand to the exact tank and support instructions; include its load and service space.

    Check stand and lid fit →
  • Choose material and depth for the intended care plan, then calculate the amount from the inside footprint. Record dry weights and displaced water separately. A generic pounds-per-gallon rule cannot describe every substrate.

    Calculate substrate quantity →
  • Compare the manufacturer rating for the 29-gallon job and measure the outlet/intake route down the taller tank.

    Compare filters →
  • If the chosen filter is air-driven, add its pump, airline, check valve and required fittings. Match actual depth, outlets and lift-tube height; keep backup mode as a separate check. A HOB or canister does not automatically require a sponge system.

    Build an air system →
  • Choose the intended water temperature and note the cooler room conditions. Use the exact heater chart, working water volume, allowable placement and an independent thermometer.

    Read heater sizing →
  • Confirm the exact fixture span and mounting arrangement. For plants, check measurement depth and conditions where the maker publishes PAR; watts alone do not establish light at the substrate.

    Check light fit →
  • Choose the actual parameters you need to measure. A general freshwater master kit does not automatically include GH and KH. Follow the current conditioner label for new water; this plan does not generate a dose.

    Plan water tests →
  • Choose a siphon that lets you work at the base without awkward overreach, and confirm the container route before filling.

    Choose water-change tools →
  • Keep connections dry, identify equipment plugs and follow the manual’s drip-loop and disconnect instructions. If a backup air pump is part of the plan, include the air path and check its battery behavior.

    Plan electrical access →

Set this equipment up in order, then make the separate cycling-readiness decision.

Checkboxes are a temporary page checklist. Printing preserves the current selections.

Measurements still to finish

  • Exact external dimensions and stand requirements for the selected aquarium.
  • Internal waterline dimensions and displacement for working volume.
  • Tank trim, wall clearance, lid openings and lighting mounts.
  • Cabinet opening, hose route and room to remove filter media.
  • Water-change route, container size and electrical access.

Use the volume tool and electricity estimate once the measurements and device labels are known. The first-year planner keeps unpriced supplies visible.

Filters rated for this tank size

The manufacturer’s tank-size range includes 29 gallons for these filters. Compare installation space and upkeep, then choose for the fish and plants you plan to keep.

Manufacturer-rated for 10–30 US gal aquariums.

Fluval 107

Compact external filter with separate maker ratings for pump output and filter circulation.

Consider: Allow room to lift out and service the canister. Measure its 13.7-inch height plus the hose route before choosing it for a cabinet.

Manufacturer-rated for aquariums up to 35 US gal; needs 2.75 in wall clearance and fits trim up to 13/16 in.

Seachem Tidal 35

Self-priming HOB filter with adjustable flow, surface skimmer, basket media, and maintenance indicator.

Consider: Rule it out if the trim is thicker than 13/16 inch or rear clearance is under 2.75 inches; measure both before ordering.

Manufacturer-rated for aquariums up to 55 US gal; needs 3 in wall clearance and fits trim up to 1 in.

Seachem Tidal 55

HOB filter with adjustable intake and return flow, surface skimmer, heater holder, and basket media.

Consider: Needs 3 inches behind the tank and trim no thicker than 1 inch. Measure both; a wall position that fits the Tidal 35 may not fit this model.
