Aquarium Tips

Substrate Depth

For most planted tanks: 1-2 inches (2.5-5cm)

For fish-only tanks: 0.5-1 inch (1.25-2.5cm)

Flow Rate

For community tanks: 4-6× tank volume per hour

For reef tanks: 10-20× tank volume per hour

Common Tank Sizes

  • 10 gallon: 20" × 10" × 12" (50.8 × 25.4 × 30.5 cm)
  • 20 gallon: 24" × 12" × 16" (61 × 30.5 × 40.6 cm)
  • 40 gallon: 36" × 18" × 16" (91.4 × 45.7 × 40.6 cm)

Aquarium Volume

Gallons:0
Liters:0

Fill your tank to about 90% capacity to leave room at the top.

Recommended Substrate

For 2" Depth (lbs):0
For 2" Depth (kg):0

This is for a planted aquarium with 2 inch substrate depth. For fish-only tanks, use half this amount.

Recommended Flow Rate

For Community/Freshwater Tanks

Flow Rate:0 - 0 GPH

GPH = Gallons Per Hour | LPH = Liters Per Hour

For Reef/Marine Tanks

Flow Rate:0 - 0 GPH

Reef tanks typically need higher flow rates (10-20× tank volume).
