darn Eric, sorry man. I went through a similar crash 3-4 years ago… and it’s very disheartening. Almost hung it up too. But glad I didn’t though. And it seems you’re not either so your tank will look even better when all is said and done. Reef on!
But on a side note, and perhaps coincidental, but another friend of mine did a chemi-clean treatment for cyano just a week ago… and many of his HE torches also bailed on him the very next day… he also can’t explained what’s ill-ing his tank. All parameters were in check.
