Ask Finn

Salvinia is a fast-growing floating fern that creates dense surface cover. Its tiny textured leaves repel water, forming a green carpet on the surface. Excellent for nutrient export and providing shade for light-sensitive plants and fish below.

Common Diseases

Nutrient Deficiency

Symptoms

Yellowing leaves, stunted growth, pale coloration, reduced vigor despite adequate light

Treatment

Add comprehensive liquid fertilizer containing macronutrients and micronutrients; increase water change frequency to boost nutrient availability; ensure adequate fish bioload

Algae Overgrowth on Leaves

Symptoms

Green or brown algae coating plant surfaces, reduced light penetration through leaves, plant appears dull

Treatment

Introduce algae-eating fish (Otocinclus, Siamese Algae Eater) or shrimp (Amano, Red Cherry); gently brush affected leaves; reduce light duration if excessive; improve water circulation

Decay and Rot

Symptoms

Mushy or disintegrating leaves, foul odor, rapid plant deterioration, brown discoloration

Treatment

Remove affected portions immediately; improve water circulation and aeration; reduce tank temperature if elevated; perform partial water changes; ensure adequate light to promote photosynthesis

Excessive Growth/Overgrowth

Symptoms

Plant rapidly covers entire water surface, blocks light to lower tank, becomes difficult to manage

Treatment

Trim regularly and remove excess growth; reduce fertilizer dosing; decrease light duration; ensure adequate nutrient balance to prevent explosive growth
