What's your thoughts on Phosguard

[navillusii]

Before I begin, I understand that not having a sump and running a 6g nano for my first tank was not the smartest thing I've every done. With that said I'm working on a 45 gallon long with a sump, co2 reactor, algae scrubber and chateo and a skimmer

I need a temp. phosphate reducer. My LFS only has phosguard, Have you used it? What did you find out? Would you use it again?

Phosguard certainly works, but has the potential to release aluminum. Rinse it well, if you use it, and if corals, especially leathers, close up, I'd stop.
