Setting up a 120 cm Tank (48 in)? Instead of googling real water volume, water-change amount, heater wattage, filter flow and CO2 bubble rate every time, enter your numbers below and get all the figures for this tank size at once. Real volume is auto-adjusted to about 80% of the brim-full volume to account for substrate and hardscape.
These are general guidelines. Optimal values vary by livestock, plants and product. Dechlorinator defaults to 10 ml per 10 L — override with your product's label.

A logging feature for water-change dates, temperature, pH and dosing — to catch problems early — is in the works.
Notify me at launch (coming soon)About 243 L when brim-full; the real volume after substrate and layout is roughly 194 L.
A common guide is 20–30% of real volume once a week. Increase frequency for heavily stocked or heavily fed tanks.
For this tank size, roughly 486–680 W is a good guide. Pick the higher end for cold rooms.
