It is designed specifically for aquariums with few plants and a significant fish population — where the fish naturally provide sufficient nitrate and phosphate, and what the plants actually lack is iron and micronutrients. Adding nitrate or phosphate in this context would fuel algae rather than plant growth; Dennerle Plants Liquid addresses the real deficiency without creating new problems.\u003c\/p\u003e\u003cp\u003eSafe for all invertebrates including shrimp, crayfish, and snails — making it one of the most reliable fertiliser options for shrimp-planted community tanks.\u003c\/p\u003e\u003ch4\u003eKey Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eContains iron, potassium, magnesium, and essential trace elements\u003c\/li\u003e\n\u003cli\u003eNo nitrate or phosphate — ideal for fish-heavy tanks where N and P are naturally sufficient\u003c\/li\u003e\n\u003cli\u003eSupports robust, healthy green plant growth\u003c\/li\u003e\n\u003cli\u003eSafe for shrimp, crayfish, and snails\u003c\/li\u003e\n\u003cli\u003eSuitable for low-tech and community aquariums\u003c\/li\u003e\n\u003cli\u003eAvailable in 125ml and 300ml\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eNutrient Declaration\u003c\/h4\u003e\u003cp\u003ePer 10ml in 100 litres of water:\u003cbr\u003eN: 0.0 mg\/l — P: 0.0 mg\/l — K: 0.8 mg\/l — Mg: 0.4 mg\/l — S: 0.9 mg\/l\u003cbr\u003eB: 0.004 mg\/l — Cu: 0.006 mg\/l — Fe: 0.07 mg\/l — Mn: 0.04 mg\/l — Mo: 0.002 mg\/l — Zn: 0.002 mg\/l\u003c\/p\u003e\u003ch4\u003eDosage Guide\u003c\/h4\u003e\u003cp\u003e1 pump stroke = 2ml per 20 litres.
