I've got a 5 inches deep Jaubert sandbed. Since I'm keeping mostly SPS, I've kept my dKH at 11, and Ca at 560ppm. This has worked quite well for me ... till yesterday!!!
In the 1.5 years that I've set up this tank, I've never disturbed the sandbed before. Yesterday, while re-arranging some corals, I noticed that my sandbed was hard like stone!!! Only the top 1/2 inch is "normal". This issue seems to be across the whole tank. This, I think, is due to the overly high dKH & Ca levels.
So far, everything seems to be OK ... water parameters are PERFECT, and corals & fishes are big, fat, and happy.
Can I assume that the sandbed is not breaking down NO3 now?
Is there anyway to break it down back into sand?
Should I leave it alone or tear it down?
Will it suddenly crash and kill my corals?
What should I do???
Worried ... sigh.
