I like and use RS Blue Bucket. You will still get brown crude with Blue Bucket.
This is a pic of my 65 tank after 1 year and 2200 gallons.

Good afternoon Jeffrey,
Thank you for contacting us, and I am happy to assist with your inquiry.
Coral Pro and Red Sea Salt are made of natural raw materials harvested from the Red Sea by a solar evaporation process. Sometimes, these raw materials may contain small amounts of inert insoluble components that can accumulate on the water surface (as a fine brownish film) or may “tint” the water giving it a yellowish color. Most of these inorganic insoluble are actually of Fe2O3 (ferric oxide) origin and therefore contributes to the general water quality by acting as a flocculating and binding substance for small organic molecules, floating bacterial films, and free orthophosphate (allowing them to be more easily removed from the aquarium water by the protein skimmer). Since the raw materials are harvested naturally the level of insoluble may change significantly from one batch to another based on the time of the year and other environmental conditions. |
It doesn't hurt anything. Lots of dirt in the ocean. lol :cool:
