Mushrooms keep melting

[muggle0981]

Paramters are fine-i test salifert and hanna checkers-

Mushrooms green hairy were 4 years old in system

Last 6 months started turning white and melting-not splitting

Ive been scraping off when they are almost gone or popping then off rocks and disposing-wondering if i should just oull the rest out

Only major water change would have been nitrates now run about 12 when they were running 22 ish

Rest of tank pics as well-lights just came on

Its something to these mushrooms as they are in different parts of the tank and they are all doing the same disintegration 1 by one over time

Dang that's crazy. After looking at your tank photos. Other shrooms and corals look good. Hmmmm....

try an ICP test. like this 3rd party test to verify things as well as find some "hidden" oddity?
