Learn exactly how much water feature cleaner to dose for a 140L pond or feature, plus a step-by-step routine to keep water clear without over-treating.

Quick answer

For a 140L water feature, dose 7 capfuls of AllPondSolutions Water Feature Cleaner (1 capful per 20 litres). Add it to the running feature and expect clearer water within minutes, but always double-check your actual water volume first.

Why 140L needs a measured dose, not a guess

Water features with tiers, spouts, or narrow basins are hard to brush clean, so a liquid treatment is often the only practical option. But dosing by eye can waste product or under-treat. The 140L figure is a useful benchmark because it matches many small preformed ponds and self-contained features. If your feature holds more or less water, scale the dose at 1 capful per 20 litres. For example, a 100L feature needs 5 capfuls, while a 200L feature needs 10. Never exceed the label rate, and remember that the 140L pack is sized for one full treatment at that volume.

When to treat and when to hold back

Use the cleaner when water turns dull or cloudy, or as part of a monthly maintenance routine. Avoid treating during very hot weather or when the feature contains fragile plants or fish that cannot be temporarily relocated—check the label for compatibility. If the feature is heavily fouled with blanket weed or sludge, manual removal first will make the treatment work faster. Also, do not mix with other chemicals on the same day; allow at least 48 hours between different products.

Step-by-step dosing routine

Measure your water volume: Calculate the actual volume in litres (length × width × depth in cm ÷ 1000 for rectangular features; use the manufacturer's figure for preformed units). Write it down. Common mistake: assuming the feature is 140L when it is not—this leads to wrong dosing. If your volume is between 120L and 160L, treat as 140L for simplicity, but never exceed 8 capfuls.
Calculate capfuls: Divide your volume by 20 to get the number of capfuls. For 140L, that is 7 capfuls. Use the cap supplied with the product; do not use a kitchen spoon. Round down to the nearest half-capful if your calculation gives a fraction—it is safer to under-dose slightly than to over-dose.
Add to the running feature: Pour the measured capfuls directly into the water while the pump is running, distributing it around the feature rather than in one spot. Common mistake: adding to still water, which slows dispersion. Run the pump for at least 30 minutes after adding to ensure full mixing.
Observe and record: Note the time and date. Water should clear within minutes to a few hours. If no improvement is seen after 24 hours, check that the dose was correct and that the feature is not heavily overloaded with organic waste. Take a photo before and after to track results and adjust future dosing if needed.
Repeat only as needed: Do not re-dose within 48 hours. For routine maintenance, treat every 2–4 weeks depending on how quickly water clouds. In hot weather or with heavy leaf fall, you may need the shorter interval. Keep a simple log of doses and dates to spot patterns and avoid over-treatment.
