SEA SHELL / AQUARIUM DECORATION
1kg/1
Seashells naturally contain carbonates, which will slowly raise the pH of water when they are submerged. Purchase seashells from a craft store or pet stores, and rinse them with warm water. Place 2 clean seashells in your tank for every 1 gallon (3.8 l) of water. Seashells dissolve very slowly, so wait at least a week before testing your pH again.
- Never use shells that have been painted.
- There is no need to remove your fish.
