Which TurboStart 700 reference is used?
This freshwater record uses the manufacturer webpage reference of 29 mL per 50 US gallons. An older manufacturer PDF uses a different reference volume; compare your bottle before using the result.
Worked examples
These illustrations use 100 L of measured water, without a decor deduction. Choose the matching stage or formulation above for your own water volume. They do not select a treatment or establish livestock suitability.
New-system / biofilter-support normal addition
| Stage | Amount or action for 100 L |
|---|---|
| New-system / biofilter-support normal addition | 15.32 mL |
Example only. Your calculation above uses your own inputs. Small amounts and powder fractions still need equipment that can measure them reliably.
Before you measure
Keep refrigerated and within expiry. Remove chlorine/chloramine first; maintain aeration and follow the five-day UV/skimmer restriction. This is not a fixed promise of cycle completion.
Product-specific checks from the calculation record
- The current product webpage says 29 mL per 50 US gallons. Older manufacturer PDFs differ; if your bottle says otherwise, resolve the label difference before using this calculation.
- Keep refrigerated and use before expiry. Remove chlorine/chloramine first, maintain aeration, and stop UV/skimming for at least five days.
What if my bottle says 40 US gallons?
Stop and resolve the label difference with Fritz. Do not average two rates or assume the older document describes your bottle.
