Advice on HLLE

[fishoholic]

My king angel gets it, carbon IME has nothing to do with it. I haven't changed out my carbon in almost a year and never noticed it getting worse when I did in the past. I have high nitrates and phosphates so I always though that might have something to do with it.

The one thing I noticed that helped was feeding a bit of nori every day. When I fed the nori every day for over a month I noticed it pretty much completely healed up. Then I cut back to 3-4 times a week. After awhile I ran out of nori and didn't get to the store for awhile and noticed the HLLE not only came back but was worse then before. Now I try to remember to feed nori more often but lately I've been lazy and slacking with my tank so my poor angel still has it.
