Well I’m about to finally start running the stuff I bought months ago.
I don’t look at it as chemical filtration. It’s just a more efficient absorbent material then what was previously used.
The more and more I look and read about those reefs that have stunning SPS dominated tanks.
The more I see use RP or PB.
Many now grow macro algae to absorb PO4 but now we have a man made absorbent that doesn’t leach it back when exhausted.
I do as much as I can (Time and my patience allowing) to prevent phosphates from entering my reef but IMO it can’t hurt. Well maybe my wallet a little
I hope to fire mine up in the morning and I will keep you all posted and the results.
