Things You'll Need
- Bucket
- Salt (rock salt, kosher salt or aquarium salt)
- Hydrometer
Instructions
Mix salt and water using the salt, the bucket and the hydrometer to get a mixture of 1.024 ppm. This is the specific density of salt water.
Remove the zeolite from the aquarium. Depending on the brand of filter, it could be in the form of an insert, a sleeve or a mesh bag.
Submerge the zeolite in the salt water. Allow it to sit for five minutes.
Rinse the zeolite thoroughly with fresh water.
Reinstall the zeoline in its respective filters. It now has about three-quarters of its capacity to absorb ammonia. Repeat in six weeks.
