Tank Maintenance - Seeking wisdom from the greats

[corallivore]

MY corals started looking similar.

I'd gotten lazy and started using a hydrometer instead of a refractometer.

Hydrometer was reading 1.25 but when I calibrated and checked because I couldn't figure out why my coral (especially my chalices) were looking so bad all of a sudden and some Algea was really starting to flourish.

The calibrated refractometer read near.y 1.3.



Have been slowly dropping salinity since but my corals were looking pretty similar to yours.

Still concerned about long term effects.

My fish, euhpyllia, zoas and shrooms did not seem to mind at all.

Thanks everyone I really appreciate the advice so far!
There is 2 great issues then right off the hop. I am using a hydrometer that is probably over a year old I have all this money in the hobby I will buy a quality refractometer before I make any salinity changes to ensure I know exactly where my tank stands at a better accuracy.

I was not aware that being at 1.022 could have such harmful affects that is very good to know.
