Common examples
60 x 30 cm tank A starting estimate for a 60 x 30 cm tank at 5 cm substrate depth. 90 x 45 cm tank A starting estimate for a 90 x 45 cm tank at 5 cm substrate depth. 120 x 50 cm tank A starting estimate for a 120 x 50 cm tank at 6 cm substrate depth. 45 x 30 cm nano tank A starting estimate for a 45 x 30 cm nano tank at 4 cm substrate depth. Planted 90 x 45 cm tank A starting estimate for a planted 90 x 45 cm tank at 8 cm substrate depth.
Substrate depth depends on livestock, plants, and tank design. Check species-specific requirements.
