Help only Millepora turning rtn/stn

[Mr Phu]

I only get rnt/stn situation on millepora they suddenly turning rnt on bottom eventhough the polyp still open strong extension . Only millepora get like this . From starting new tank i lost 5 pcs of millepora with same situation ‍ . Another kind of acropora dont get like this eventhough i have a lots of sensitive acro like deep water smoth skin
My tank 1200 liter . Water water pernanment : 1027 - canxi 460 - alk 7.5 to 7.8 - mg 1335 - no3 is 0 - po4 is 0.03 to 0.1 .

 

[Mr. Mojo Rising]

I would frag a couple of healthy branches before its all gone. I am not aware of any way to stop it.

Are these newer (6-8 months) mariculture colonies?

Yes they are.

He made this thread about the same issue earlier today: https://www.reef2reef.com/threads/help-no3-increase.1091103/

Ok..i see. N03 has been zero and p04 looking like .03. Looks like there's a lot of acro competing for nutrients with a refugium of sorts? Not sure if the n03 getting dosed is in an easily consumable form at that. May be easier to feed the system more food for fish. Either way..mariculture acros can come with a host of things to navigate for succeeding. Could be the low nutrients, could be too much competition for whatever trace elements are available, could be bacterial. The base of the one colony may be shaded out. I know it's not exactly a "that's it" reply because it could be a combo of many things. As mentioned earlier a fragging may be the best road to take on the ones suffering.

AEFW is also a possibility. Adding that many mariculture colonies without QT is very risky business.

I don’t think AEFW are causing basal recession, but I wouldn’t be surprised if he had them. He said it’s basically affecting the milleporas, which AEFW really like.

 

[billyocean]

Thats true..i didn't think about aefw or bugs. Perhaps a pull and microscope will shed some light on that. At least a good look with lights off to see if anything is running around bug wise. Depending on the aefw it will look different. Old aefw will have the circular bite marks/patches with tight eggs. Newer aefw can look like rtn almost and has sporadic eggs.

I have feed coral 3 time a day with redsea AB+ and reef roid for balance lack of nutrition is that okey ?

 

[Mr Phu]

I have dip this rtn millepora on today but not see anything its dont have AEFW . I had look acropora at night no any eggs or bite marks / patches

I feel like that's overkill and red sea ab+ never made a difference for my acros. The excess aminos from all the roids and ab+ could be detrimental at that rate of dosing but it's not an area of my expertise.

I was thinking the same thing. Amino acids can fuel bacteria, and having the pathogenic types flourish is not ideal. We don’t know if it’s bacterial, but it is a possibility based on the symptoms.

If it were me, I’d skim heavy and use activated carbon. Keep the lights strong and use a daylight spectrum. The flow should also be strong. The polyps should dance around.

I would stop reef roids and amino acids. You have enough phosphate, so you don’t need to worry about a phosphate deficiency.

I’ll write a new post about getting nitrogen in your system soon.

 

[Miami Reef]

This is most optimal. Get food-grade ammonium bicarbonate. Your goal is to dose low amounts throughout the day (maybe 2-3 doses). Any excess ammonia will turn into nitrate, so you can use your nitrate test to gauge the ammonium dose.

If nitrate is increasing, that means your corals are having their nitrogen needs met.

DIY Ammonia dosing for low nitrate systems

Some reef aquaria have chronic low nitrogen availability. One indicator is very low nitrate. Nitrate dosing is a fine remedy, but it is possible that ammonia dosing may be more beneficial for some organisms since ammonia can be energetically easier to assimilate than is nitrate. For this...

Thanks for support but now no3 is zero any problem if i dont feed the coral ? My tank dont have any fish

You have a bottle of fauna marine nitrate. I saw it in the other thread. Dose more of it.

 

[Mr Phu]

They said do not overdose , just maximum 2ppm for day ‍and should i have to turn off skimmer when dosing ?

Forget their instructions. You have a large bioload. Skimmers don’t remove nitrate or ammonia.

Thanks Sir

Have you cut the base off of your millepora and inspected for green boring algae? I had a mariculture tenuis that did the same thing to me and when I cut the base off, it had green algae in the skeleton.

 

[Mr Phu]

Yes i frag it to 3 pcs already and u mean inspected for green boring algae ? I dont know what is it
