+1I started my tank with 80% dead rock and 20% LR.
I was thinking that rock is just like any other filter media. It does get dirty and in a way exhausted. There must come a point in time in a reef where live rock stores enough dissolved organic matter that it actually contributes to a decline in water quality i.e. "old tank syndrome"
Rich, do you remember last year at about this time when my tank wasn't so good? You, Kaesi and Dave all came over and said the same thing. My PO4 was high. You guys first said, remove the fuge. Next, you said to remove the rock I was using to baffle water going into my sump. The rock was just loaded with PO4 NO3 and all kinds of other crap. Both the fuge and those rocks were leaching more crap into the tank than I could possibly remove with a NW/MW skimmer. Within 2 weeks of removing both the fuge and the rocks, my PO4 was within acceptable levels without me doing any water changes.I was thinking that rock is just like any other filter media.

future tank I might set up if I decide to smoke a pile of crack rocks and swallow 3 pounds of crazy pills.
