No more brown deposits from silicates! Silicates are found in tap water or are released from the substrate and can promote the growth of diatoms. These can form unsightly brown deposits on plants and the substrate. Bio-Exit Silicate neutralizes silicates quickly and effectively. Dosage: 10 ml per 20 liters on day 1 and day 3. No water change for 7 days after the first dose.
