Simply pour the recommended amount of salt directly into the water, evenly inside the perimeter of the
pool or spa, to bring the concentration to the recommended level. Then, if available, turn on the jets
circulation system, etc., to help mix it in. If the water is cold, it may take several hours for the salt to fully
dissolve.

and Salt Low) lights at the same time. When in doubt, start with less salt than you think you need, since
it is much easier to add more salt than it is to remove it, since removing it requires draining pool/spa
water and adding fresh water. If you have a water softener, your water may already have some salt in it,
so in that case, before adding any salt, let the water get to temperature and then turn the MegaChlor
That way, you can check the current level and gradually add salt in as needed.
Note: If you are trying to decide which salt you want to use, we typically recommend sodium chloride
(NaCl), since it is often more inexpensive, all while still being effective. If you have sensitive skin, sodium
bromide (NaBr) may be even more gentle than sodium chloride (NaCl) already is, so feel free to check
with your dermatologist for which option would be best for you.
