Tips don’t look healthy

[bellasdad0911]

I have noticed the tips of my acros haven’t looked very well last few days. I did have to rescape the main stack as my goby cause the foundation to move thus having to redo it. These are under a Hydra 52. The blue one is 8 Inches from the water line and the green is about 15 inches. The hydra is set at 60% reduction.

Levels are :

Po4 .02 on Hanna
No4 barely detectable
Alk 9.5
Calcium 500
Salinity 1.025-1.026
Temp 79

Not sure if it’s could be too much light, or flow? below all the tips the color is very vibrant on both. Any help would be great.

Did these move up in light? I'd try and get the nitrates and phosphates up a tad and see how they do. Mine do best when phosphates are around 0.04 or above. If my phosphates drop below 0.04 for more than a few days growth slows and eventually I'll get some lightening in color usually at the tips. But I run my alkalinity around 11, so 9.5 isn't that high. Usually alkalinity fluctuations is the main culprit.

Is your alk steady at 9.5? A spike in alk often causes burnt tips. You might want to lower to around 8.5 and make sure it is stable. If no algae is growing on the tips, it should recover fully.

No algae is showing up yet. Yes they did move up a little but as they did, I increased the reduction. I did add some phosphate tonight cause I too thought it was too low. I will heavy feed for a while to get nitrates up. 9.5 is pretty steady and still haven’t had to dose. Weekly water changes with Red Sea coral pro bring it up and keep it right around there. It very hard to get it to come down.
