I use chemipure elite..

And I think if Jesus we're around he would use it too!

This stuff really does wonders

I use it..along with Purigen

I've been running it through my phophate reactor for about a year now and it works great. I replace it every 6 weeks and just run it from my tank through the reactor into a bucket until it runs clear. Then top off with some some new saltwater. Keeps my water crystal clear..
