Sps burnt tips

[datboichucky]

Hello everyone I’m getting a bit frustrated because I’m noticing some burnt tips and some rtn on a few of my acros. Only changes I have done was transfer everything to my new 120 gallon tank from my Red Sea I used all same live rock a refugium so no lose in bacteria. I replaced all 8 bulbs in my ati fixture 5 blue plus 2 coral plus and 1 purple plus. I’m running 2 bulbs from noon-7pm and 6 bulbs 3pm to 7pm all at 100%. I also started running gfo due to my phosphates Being .12. I tested my alk 3x today to check for all swings and it’s staying at a solid 8.9.

Burnt tips or growth? Hard to tell in pics under heavy blues

My suspect then would be lighting. I always with bulb change use acclimation setting and resume to normal lighting

Okay I’ll just place it higher and bring the percentage down to 75% and cut the hours down

Definitely burnt tips from my experience. However, if you bringing the corals higher but decreasing the intensity, wouldn't that be the same as what you're doing right now? I usually acclimate new corals on frag racks in the middle of my tank and slowly bring it up until very close to the surface, after that, I glue them wherever I want them to stay at.

My guess would be a rapid reduction in PO4. If your PO4 was at .12 ppm and you used gfo to bring it down to 0.03 ppm, it probably was to quick and that stressed the corals.

+1 ^ exactly. Couldn't have said better myself

The rapid intensity of UV exposure due to the quick decrease of PO4 in the water had a negative impact on them for sure. GFO is some pretty power stuff. I don't use it.

I placed the light higher and decreased the intensity to 75%

Thank you for your input on that makes sense. Anything you recommend to help this issue? i placed the light higher and decreased the intensity to 75%

Many reefers have had negative experiences with gfo. As stated above it can lower po4 to fast.

I mean the damage is done now i just hope they will bounce back. Debating if i should just let the reactor stay on since its staying consistent at .03

Like you said damage is done but I would definitely cut the GFO. Also .03-.09 is acceptable range and some reefs even thrive in higher PO4 especially in conjunction with higher alkalinity.

I'd reduce the lighting volume 15-20% for a few days, keep water quality high and remove that GFO.

If i stop GFO it jumps right back up i feed heavy

problem is of I stop gfo phosphates will jump back up to the .12 range I have a high nutrient tank nitrates are at 50 on salifert test

Unfortunately GFO is not a fix for heavy feeding Over feeding causes many problems in the aquariums and you can afford to increase your PO4. Nitrates will natural improve with a managed feeding regimen.

This is just my recommendation but you know your situation better than anyone else.

Okay I appreciate your input I shall take the gfo out and see how everything goes after that. Hoping they bounce back

PO4 of 0.12 is fine, especially with higher NO3. Like @pathot984 said, managing your feeding is a better solution than gfo.

Found another issue Hanna checker was off showing 8.9 for alk. Just did a salifert test it’s at 10
