Any ideas why im getting burnt tips?

[Dannycelluk]

Anyone got any ideas why some of my corals are getting burnt tips?

Water parameters are pretty spot on, flow is good. only thing I can think is that the LED's are too bright, but this particular coral was only a third up the tank and i have others that are at the top and look really healthy.

I have 3 corals in my tank this, a tri-colour and another similar to this but pink all getting burnt tips.

Have loads of other colonies doing great, good polyp extension/colour.

Google high alk carbon burnt tips

Hi thanks for the reply.

My KH is stable at 8. I do however use carbon, as I use Ozone.

@Russ265

I am going to say lack of nutrients to support the growth

right on target.
the answers about alk burn are also correct.

higher nutrients can allow more alk.
since your alk is already at 8. id look to up no3 or po4 if running aggressive gfo.

Ok thanks, my nitrates are very low, phosphates are a little high

bring nitrates up 2-5ppm and po4 at .02ppm and you should be good.

either way i wouldnt worry too much about your growth tips.

I've been feeding quite heavily to try and increase, might back the algae scrubber off some more then

overfeeding sometimes works. mostly brings cyano.
tbh i just dose potassium nitrate.

How are you filtering out the Ozone? I have seen burnt tips when some Ozone use was a little high and getting into the tank. I would check you settings.

I have the same issue month ago, all my parameter are stable
Alk 8.4 dkh
Cal 420
Mag 1280-1320
No3 ~5
Po4 0.02
Then i check the rodi water tds it read 25 and after i fix the rodi tds i did 50% water change. Since then my coral healing from dying tip

Yes check your source water. Especially if your water has chloramines. Bad RO/DI can cause the same burned tips as high alk.
