Sorry it too me so long to reply I have been doing a lot of travel lately between a new Grandson and work.I have been watching your build for a while, and just watched the video with the new fish additions! Pretty awesome to see that many big tangs look small in your tank!
I am about to start adding rock to my new tank, and I’m curious what kind of cleaning process you did before adding your old rock? I want to make sure I get it right
The one place a really failed was cleaning my old rock. I removed from my old tank a few years prior and just let it dry in the sun. I knew my tank was clean so just was nt really concerned. But wow was I wrong the old rock had so much Phosphate it taken me a year to finally get the Phosphate and Nitrate at appropriate levels.
I would suggest a good cleaning and then curing in brute can checking Nitrate and Phosphate before using the old rock.
As of testing today my
Nitrate is 5
Phosphate .05
PH 8.32
ALK 7.74
Mag 1599 This has been high for a while but I can't seam to get it down
