The active ingredient in AquaForte Alg-Stop is "packed" inside an additive that algae eagerly take in. Alg-Stop will block any further, vital, nutrient uptake. It does not withdraw nutrients from the water but makes the nutrients unavailable for the algae. Alg-Stop penetrates the algae and destroys the calcium skeleton which releases the algae from the surface so they can be filtered out of the water. Any measurable phosphate levels after the addition of Alg-Stop are no more relevant and can be neglected. Alg-Stop does not contain ammonium compounds or metal salts. Alg-Stop dissolves quickly in water so the algae can take it in fast. USE AND DOSAGE POWDER The first month use 100 gms per 3000 liters of pond water every 10 days. For maintenance use 100 gms per 3000 liters of pond water at least once per month. Apply the Alg-Stop directly in the pond (around edge of pond area). Remove dead blanket weed and clean filters regularly. USE AND DOSAGE LIQUID The first month use 100 ml per 3000 liters of pond water every 10 days. For maintenance use 100 ml per 3000 liters of pond water at least once per month. Apply the Alg-Stop directly in the pond (around edge of pond area). Remove dead blanket weed and clean filters regularly. Please note when using Alg-Stop: do not use Alg-Stop in combination with other blanket weed products, active carbon, nitrate resin and ozone. For optimal use please check water values before using Alg-Stop: GH value (optimal 12, at least 6), KH value (optimal 8, at least 4). Please dosage again after heavy rainfall or water changes. Please double the dosage for heavy algae areas or shallow water zones. Alg-Stop is perfectly suited for natural swimming ponds. To keep the pond free of blanket weed, use Alg-Stop at least once per month. EXAMPLE YEARLY USAGE: 1m³ pond water = 0,4 kg/ltr per year (0,5 kg/ltr including start-up dosage) 5m³ pond water = 2,1 kg/ltr per year (2,6 kg/ltr including start-up dosage) 10m³ pond water = 4,2 kg/ltr per year (5,2 kg/ltr including start-up dosage) 25m³ pond water = 10,8 kg/ltr per year (13 kg/ltr including start-up dosage)
