aluminum sulfate

[pedro]

the aluminum sulfate can be uzade to export phosphates?

Many would argue that Aluminum in this form or Aluminum Oxide are not appropriate for a Reef Aquarium...

Highly effective as long as the solids can be exported... GFO and GFH also highly appropriate.

I currently still use SeaKlear in my tank to control phosphates. I run a mechanical filter to remove the snot left over.

I would not use aluminum sulfate. It will deplete alkalinity and the soluble aluminum will irritate corals at 5 ppm or less, as I showed in a previous article:
