Tank Kit Builder
Answer a few quick questions and get a recommended equipment checklist for your aquarium — sized to your tank, with the numbers to look for. A starting point, not exact figures: use the linked calculators for your precise values.
How your kit is worked out
The Tank Kit Builder turns your answers into a practical shopping checklist. Each recommendation uses a well-established aquarium rule of thumb — filter turnover from your tank volume, heater wattage scaled to the water, substrate depth for your planting style, and so on. These are sensible starting points to plan and budget a setup, not precise specifications.
For exact figures, follow the links on each item into our dedicated calculators: the filter capacity calculator to match a real filter to your stocking, the substrate calculator for an accurate bag count from your tank's actual footprint, and the tank volume calculator for your true net water volume. Planning CO₂? The CO₂ cylinder estimator and drop checker guide help you dial it in, and the parameter log tracks your water once the tank is running.
Why the numbers are ranges, not rules
Every tank is different — room temperature, fish species, plant mass and aquascape all shift the ideal kit. Filter turnover of four to six times your volume per hour suits most community tanks, but heavily stocked or high-flow layouts want more; heater wattage near one watt per litre works for a typically heated room but a cold room needs more. Treat the checklist as a guide, then refine with the calculators and your own judgement.
