Treating Tap Water?

[Doo]

Hi All

I have read that some reefers (Edmonton) are using tap water treated with "PRIME" and have had good success...

Has anyone tried using the "Super Strength Tap Water Conditioner" made by Aquarium Pharmaceutical??? (pic attached)

I have used this for about 8+ years on all my FW tanks and some of the FW fish I have had were very delicate, yet this product has never failed me on the FW side of things...

If it works on FW does that mean it should work on SW???
I imagine that the removing the chlorine and breaking the chloramine bond should be the same on tap water regardless; however a FW setup may be more forgiving??

I wanted to ask before I mess things up - lol
Please let me know your thoughts??

Thank you
