Phosban or Rowaphos for Po4 removal?

[cwegescheide]

I've got a few buckets of Phosban I got a long time ago and have been running it in a bag in my sump. I recently tested my Po4 with a Hanna meter and .14!! So I am now running it in a Phosban reactor. I hear though Rowaphos is much better at removing Phosphate.

Whats your experience? What things to watch out for when running it actively? I have heard you can do a lot of damage to SPS if you pull out Phosphate too quickly.

Right now I have my reactor about half full of Phosban and running it pretty slow. Slowly turning over the media in the chamber. I will have my Po4 tested next weekend with my LFS's Hanna Meter and then go from there.

Thanks,
Chris
