Dead Xenia removal

[randallino]

I lost my Xenia also last week, I figured it was from the high temps ~32 C and it only took about 24 hrs. So what I did was pull the rock that the Xenia was on and scrubbed it with a toothbrush, did a couple of water changes and changed the carbon. With the Xenia dying you could experience a bacteria bloom so oxygen levels may drop. My tank is back to normal (no Xenia) after a week.
