Burned tips sps question.

[Shinte122305]

My parameters have been rock steady for 3 weeks now but the corals havent recovered the tips yet. they have not gotten worse so thats a good thing.

Now what keeps happening is over a few days brown algae starts growing on the burned tips so ive cut it off but it just keeps happening over and over and over. nitrates are at 5ppm phosphates are 0.003 i have zero algae issues except on burned tips lol.

I read somewhere here to use super glue on the burned tip is this a real solution?

What's your lights? Have you tested potassium?
Burnt tips can come from
Too much light
High no3
Sudden spike in alk
Low K+
Sudden and quick reduction in po4

The last one is very common, people see po4, they add strong po4 remover and drop the po4 too quick. This shock coral and cause all sort of issues one common is burnt tip.
Its actually a from of STN

Any of the above causes ring a bell?

Thanks for the fast response! and It was an Alk spike i already fixed that issue, im currently keeping it at 8.5-9. My issue now is keeping algae off the burned tips so the coral can recover. I cut the tip and in 3 days brown algae is back =(

I would leave the algae alone and stop cutting the coral. Algae will not hurt the coral itself. It will latch to the dead part oonly.
When small part of sps die and brown algae cover it I leave it alone. Many time coral recover and go back even

Remember the coral already stresses. Every time you play with it, take it out, cut it..etc all will just add to its stress.
In such situations best is to leave the coral recover..
That is ofcoirse assuming that the originsl stress source is already removed and no longer the issue.
Just keep system steady and no student changes in parameters.
