White tips acro. Pc rainbow

[GSnake]

Hello, the pictures are of pc rainbow acro. I just am not having luck with them. My last one I was sure it was a par issue and since then I rented a par meter. This one is getting 350 par, alk 8 cal 420 mg 1340 no3 near zero and po3 0.03.
The white parts are facing towards the light. And I think it might be new growth? Im Hoping it is.
This is how the last one started and stn along the side a while after. Im Just a tad worried.

Dont mind the suspicious emerald crab...

By the way my my other across are showing no distress signs.

Looks like stn to me sorry man

Pc rainbow has always been one that gets burnt tips for me. Not sure if it’s too much light or too high alk, or something else.

Yours looks particularly bad though. That dead spot that is t on the tips is concerning.

What all are you dosing?

 

[GSnake]

Soda ash, cal mix and mg mix randy's 2 part recipe, through automatic doser. Red sea reef energy and phytoplankton manual dose every other day. And carbon via box biopellets.

I can try lower alk, but ready to trim the tip off or glue the white area

All of your corals look starved judging from your other other threads. Ditch the biopellets and your sps will thank you

Do they,? Ok. I was thinking about doing that last week. I'll take out about 70% of them. There are bacterial diversity benefits I'd like to keep.
On the other hand I could reduce my charto five lights intensity or time period, they are at 100 intensity for 12 hrs now.

More fish is always good to me.
What exactly are box biopellets? Just want to make sure I’m giving you the correct advice

 

[GSnake]

It was the autocorrect..
it was supposed to be NPX biopellets

That’s what I thought
Been there, done that and killed thousands worth of sps. But my no3/po4 was “ideal”.

I would get rid of all of them ASAP. They’re over stripping your water. I don’t believe they add any biological benefits unless you consider starved/dying acros beneficial.

Ya I have to say they things looked better with extra nutrients before using pellets. I've never had a real nitrate issue myself cause I always use a cheato fuge. I guess this is just too much now.
I wanted to make a tank as close to nsw as possible and apparently there's tons more bacteria in the ocean compared to our tanks. Adding biopellets was just suppose to support a higher bacterial count.
But if it works better without it all together..

." Sensitive corals, like Acropora, do not thrive in the high-bacteria-count/high-TOC-level tanks examined, although soft corals do well (see pictures). On the other hand, SPS corals do well in the low-bacteria-count/low-TOC-level tanks" from

Bacterial Counts in Reef Aquarium Water: Baseline Values and Modulation by Carbon Dosing, Protein Skimming, and Granular Activated Carbon Filtration

What are the bacteria populations in the water column of reef tanks, and how does that value compare with bacterial counts in authentic reef water? Does carbon dosing indeed increase water column bacteria populations (i.e., is growth carbon limited)? Does mechanical filtration (protein skimming...

Worth a look through

Toc is total organic carbon by the way

obviously pretty small still I only have had it for about 2.5 months but the one on the left is my PC rainbow and is growing well. It’s around 370 par, alk 9, calc 440, mag 1250. pH 8.1

I’m running modified Triton with Kalk in my Ato for pH and I use zeobak and Pohls Xtra, and Algaebarn live phyto. I have a heavy fish load in my tank too.

 

[Charlie’s Frags]

Show me a peer reviewed study with pics of their acropora in a 50-100g tank and I’ll show the first time I care.

that is some great PE. I think I see orange passion there, maybe even marvin the martian, walt disney or homewrecker too but not too sure of the rest.
I took out the pellets today, and put my skimmer back on for now to reduce bacterial levels, maybe do a few water changes this week too to reduce the added carbon too i am not going to be using the skimmer long term.
can you share a bit about your system? whats your nitrate at, and what filter methods do you use. How old and large is your system, and what do you dose (outside of alk/cal/mag) as well as water change frequency if any,

also, havent noticed the pc rainbow get any worse, im hoping it recovers from where it is. if it gets worse this week ill be clipping off the dead parts and crossing my fingers again after that.

50g cube
No3 15-30
Po4 0.10-0.30
Skimmer and chaeto in the sump
I dose tropic marin all for reef and brs pharma kalk through my ato
I also dose kz flatworm stop for coral vitality

Do you dose anything else for you chaeto, or does the all for reef keep it growing well, too?

100% intensity for 12 hours seems like way too much light and photoperiod. You want to ramp up and to and hold your highest point in the photoperiod for a short period of time before ramping down for the night. Try something like 4 hours of ramp up, 4 hours of your max intensity (whatever that may be) , and 4 hours of ramp down. That will simulate a more natural photoperiod and should be overall better for all of your corals.

I do not dose anything special for the chaeto. I assume the fish waste keeps it growing.

I think it would be responsible to add that pulling biopellets too fast was linked with a number of tank crashes. I think the best practice would be to do it gradually some how
