๐ŸŒฟ Dipping Aquarium Plants in Alum

A Safe Way to Remove Pests Before Adding Plants to Your Tank

๐Ÿ“– Why Dip Plants? New aquarium plants can carry unwanted hitchhikers like snails, snail eggs, planaria, or tiny insects. Dipping plants in an alum solution is an effective way to disinfect them before adding to your aquarium.

๐Ÿงช What Youโ€™ll Need

  • Alum powder (commonly available in the spice aisle or aquarium supply)
  • A clean bucket or container
  • Dechlorinated water
  • Measuring spoon

๐Ÿ›  Step-by-Step Instructions

  • Mix the Solution
  • Dissolve 1โ€“3 tablespoons of alum per gallon of water in a container.
  • Stir until fully dissolved.
  • Soak the Plants
  • Submerge the plants completely in the alum solution.
  • Soak for 2โ€“3 hours (some hobbyists extend up to 24 hours for stubborn pests, but sensitive plants may be affected).
  • Rinse Thoroughly
  • After dipping, rinse plants well in clean, dechlorinated water.
  • This removes excess alum and any dead hitchhikers.
  • Inspect Before Planting
  • Double-check for snails or eggs, then add plants safely to your tank.

โš ๏ธ Tips & Cautions

  • Some delicate plants (like mosses or fine-leaved stems) may not tolerate long alum dips. Test with shorter times first.
  • Do not pour alum solution into your aquarium โ€” always rinse plants before use.
  • Quarantining plants for a few days after dipping gives extra assurance.
