- Enter tank outer physical dimensions (length, width, height in cm).
- Input cumulative fish biomass in inches of mature length.
- Review net water volume (factoring substrate displacement), hourly turnover multiplier, and recommended water change volume.
Scientific & Clinical Inquiries (FAQ)
Why subtract 15% from gross tank volume?
Substrate (gravel/sand), rocks, driftwood, and internal equipment displace water, leaving actual swimming volume approximately 10-18% below outer box math.
What is the recommended hourly turnover rate?
Standard freshwater planted aquaria require 4x-6x turnover; high-waste cichlid or monster fish setups demand 8x-12x filtration cycles per hour.
How is the 1-inch-per-gallon guideline interpreted?
It applies strictly to slender, small-bodied community fish (e.g., tetras). Deep-bodied fish (goldfish, cichlids) produce exponential waste relative to length.
