Is Purple Up smart?

How do you use the epsom salt to dose? New to adding coral and was not aware that the inexpensive epson salt will help with Mg.

I too never tested for Mg, dkh, or Phospates in the past now will be getting a good test kit to test for all the new needs of the corals I guess. I have always tested Nitrites, Ammonia, PH, Calcium, and just added Nitrates. Will soon be adding Mg, dkh, Iodine, and phosphates.

 

If you are going to go this route, my LFS suggested coralline stimulator from Florida Aqua Farms, they stated it was twice as good for about 5 bucks less.
I figured if they wanted to sell me something cheaper than what i had in my hand, must be good stuff.

I haven't really noticed any change after using it though.

 

I dump a small handful in my sump or overflow every week (or 2 when I remember) and jsut let it disolve and do its thing. Test your Mg and adjust accordingly - keep an eye on your calcium, these two are notorious for fighting one another

 

i like aragamilk for an easy to dose product.

 

i tried pu and stopped .after realizing scraping it combined with great water works great.then i started using it as Ca supplement but also stopped after getting argonite sand now i replenish my sand ever 3 months or so and now thats great so now i just add sand and my Coraline seems to thrive now

 

I use purple up, its done well so far. But I like it for the CA and the iodine, shrimps molt well lol. I think if you have a healthy system and coraline algae present, it seems to spread either way.
