@Rick.45cal thank you so much for all your help and insight, I feel I'm making progress, and much wider to go slowly, I believe in the beginning of this thread I was really trying to hurry and wanted something within the week, but now I've settled back and just being patient

I feel your pain. I've been battling a similar issue for almost 3 years. NO3 hasn't gone past ~20ppm, but PO4 is never more than .01-.02ppm (0.005 according to last Triton), even with dosing twice daily. I will say that my SPS perked up considerably when I started dosing PO4 daily.

definitely following to hear some of the advice.
Which PO4 you dosing
Thanks

Hey rick.45cal, when should I put my fuge back on line ? Cuz my sump is setup to have a fuge as mechanical filtration???

If your nutrient levels have stopped bottoming out then I’d say your safe to start it back up. I’d go slow with a small amount of Chaeto to start and just keep track of everything so you can prevent bottoming out with no nutrients :)

Hey everyone, just like to give an update , auto water changes still happening between 2 and 3 gallons a day, No3 down to roughly between 16 and 32 , happy day finally some progress, po4 has creeped up a lil to 0.08 but I feel I can control that I've been dosing neophos to my ato and my fresh salt water ato ratio is 1ml to every gallon, and FSW is .5 ml for every gallon, my fuge has gone from brown to green, I've slowly started ramping my LEDs back up I'm really excited to start seeing some growth !!
Thank you everyone so much for all of your input

@Rick.45cal and @Brew12, what are your opinions on @vdubreefer performing a couple of water changes this weekend to bring his NO3 down to a more reasonable level, i.e. 20 ppm, and then starting the regiment of dosing PO4 that was mentioned?

Would this help him get to a more balanced system that would start growing more desirable levels of the right bacteria and bring his tank into balance sooner. I know that patience is the key to successful reefing, but I don't see the harm in reducing his NO3 a little quicker.

I would also recommend to @vdubreefer to slowly increase the intensity on his light. Many of the desirable things we try to grow in the tank, even algae, depend on light. I think that running the radions at 38% and 18% is too low for a 90 gallon display tank. Without giving the organisms the light they need, they aren't going to use the NO3 and PO4 that is there. The Zooxanthella need light, PO4, and NO3. I think your corals may also be light limited as well as PO4 limited. Two strikes against them. Take it slow raising the lights though, do it over a month at least, maybe two.
Hey island, so I took your advice I have increased the light intensity of my radions over the course of a couple weeks, 1) because I would like more growth, now that my no3 levels are dropping, 2) some of my montipora and other corals on my left side rock structure aren't looking very good, I cant tell if it's too much light or too little

That’s a good sign :)
Hey @Rick.45cal, I've noticed my corals colors have gotten better but my growth has been next to nothing , my Acros on the left side seem to do well. The ones on my right side seem to be dying, my left side light is at 40% and my right side is around 20 cuz I had some montoporas, and I thought new acro frags didnt need 250 par, they were doing good, now all my montis look like death and my bonsai and frog skin acro are slowly dying how do I diagnose acro problems

Can you snap some pictures? It’s possible your light levels are too low on the right side. My whole tank is very bright (I run a mix of t5’s and LEDs). My acros sit in about 600 PAR, my montis do too. The ones that don’t like so much light are down on the bottom of my tank where its more like 375-385 PAR. But I also have very high water flow within the tank. (It doesn’t need to be this bright, I’m just using it as an example).

It will take time for you to start seeing new growth after a phosphate deficiency. The improved colors is a good sign :)

Are these par levels required for frags as well ?? Plus, with all the different "designer" names for fuzzy sticks how am I supposed to distinguish between higher light acros and lower light acros?? Also I'll post pictures tomorrow and I'll definitely start ramping my radions up, I do have a syneye par meter too.

My lighting is brighter than most folks tanks. But not as bright as places on the reef, and there are members here with higher light tanks than mine. These high light levels AREN’T required or even “better”. But that being said it’s pretty easy to have inadequate light! If I was in your shoes I would gradually increase my intensity every 7 days until most of my corals were around 350-400 PAR, then I would leave it alone and see what happens, if six months from now if it’s not satisfactory then I’d consider increasing further. The trick is to gradually do it every 7 days and work your way up there over a month or so. You don’t want to give any of them a sunburn. (If you have nitrates and phosphates, you shouldn’t have much of a problem, unless you do it all at once).

I never worried about what acros liked higher or lower light, the only choice in my tank is lots of light. I have a couple montis that I was told liked shady locations so that’s where they got put, but “shady” in my tank is 350 PAR. :eek:

@vdubreefer When I acclimated frags to my lighting in my tank, I did it by putting them on a magnetic frag rack and I started it at just above the sand level, every 7 days I would move the frag rack 6” up the side of the tank (27.5” deep tank), by the 3 rd week the frags were the same height as the where most of them would be placed, the next week I stuck them in their places on the rock work. ;)

Ok, very helpful, I've been wondering if maybe these corals were dying because they basically were starving because they didnt have enough light, heres some pictures the three acros on the lower right one the shelf got moved there fro. The left side a few days ago but all the corals I've taken pictures of are corals from the left side, "lower side"

Hello everybody, I'm on my last limb trying to figure this out, I'm ready to test down and start over, I've got a 90 g bare bottom tank I've got three fish 1 purple tang, 1 vlamingi tang, 1 clown fish. I've had it up for three years I've never grown cheato I've never grown coraline and my corals have grown especially slow if at all, I'm so fed up with it, I'm bare bottom with minimalist aquascape and running Triton, my rodi water is clean enough, I have a theory I'd like to toss around and see what the community thinks cuz I'm so done I really am, so when I did my aquascape I ordered 85lbs of LR from brs it is the reef saver rock, and If I had to guess I bet I maybe have 60lbs in my tank if I had to guess, I just put the rest into a bin to cure about 2 weeks ago, I'm thinking I have high nitrates because I don't have enough LR in my tank.
Also for the other part of my question above I've had undectable po4 forever never had any bad green algea in my tank only brown looking nasty stuff, my corals are very pale, and grown extremely slow, and my cheato doesn't grow at all and I've got a kessil H380 over my fuge. For my skimmer I'm running a B. Magus A8, and after thinking through my equipment I chose I've decided that my skimmer is pulling WAAY too much phosphate out of the water, i can dose neophos at night to bring my level up to .03 and itll stay like that for 24hrs with the skimmer off.
If I turn my skimmer on, by the next day my po4 will have dropped back to zero,
So I am over skimming my system,

Conclusion, add more LR, and possibly a deep or just a regular non deep sand bed to refugium, and buy a new skimmer sized for my tank.

Agree or disagree ??
Share your opinion I'm open to whatever you have to say at this point.
Thank you

If possible try ICP test. It's may get to the root of the problem

Hey Rick heres is my par readings, i took with my syneye par meter, geez now I feel really dumb, I never realized how low my lights were no wonder my corals are dying
Rick I really appreciate this, If i met you in person. I'd give you a high five cuz you've seriously have helped me out so much, I'll slowly start ramping the lights up, and they will both be the same intensity, no more low side high side,

@vdubreefer
So it looks to me like a lot of the damage, especially with your montis is related to the phosphate deficiency. The patchy dead areas are a dead give away that you had phosphate starvation in the presence of ample nitrates. The acros look like they probably suffered the same fate and, or light starvation or a combination of several things going on. You’ve solved the problem but the damage is permanent and will take a long time for the corals to recover and grow over the areas. I still have damage on several montis that suffered the same fate as yours, and that event was several months ago. My colonies are actively growing new parts, but the dead damaged areas are still a no go. Sorry but now you are realizing the long term effects of what happens in this scenario. (Stick with it, you’ll get there. It’s going to take some healing time.

To ease your mind you can always do what @Jomama suggested and do an ICP test. I personally would choose the ATI ICP-OES test because they will also test a sample of your DI water for contamination. It may not reveal anything, or it may tell you something that may be an issue to address in this process.

Regardless I think you are headed down the right path now, try and keep things stable and keep detectable NO3 and PO4 and things should gradually recover.

Here’s my monti colonies still with damage from me allowing my phosphates drop to undetectable with ample nitrates available. (This kind of damage happens EXTREMELY fast in a bright light environment, lower light environments take longer for the damage to form.). Yes that is cyano, but it’s not the cause of the damage, it is feeding on the dead tissue, or what remains in the skeleton. If you notice the outer rim of the monti is actively growing and healthy but the inner tissue is rough and struggling. (This coral is actively recovering, and was in much worse shape a few months ago). The effects of phosphate starvation in the presence of nitrates is a prolonged and drawn out process even when the drop in PO4 was a short punctuated event. :) For the record, these monti colonies were only saved because I recognized right away what was happening and reacted quickly to stop the event.

Well I can tell things are getting better by color in some other corals are getting better, I bought some cheato and put it in the sump and it's been in there for about a week and it is already starting to grow, so I know things are getting better, now I gotta work on the lights getting brighter, but honestly it feels soo good knowing things are getting better it brings back my excitement of the hobby.
If my reef is doing bad, I start feeling depressed, if it's doing good I feel happy, it's sad really but it's how it is.
This hobby is my entire world I love it, I'm still a newbie and I probably should have gone all LPS for a while but I just love sps, acros mainly. so I'm sure this wont be the only time I encounter problems,but it's nice knowing there are people like you willing to help.
I know I've said it before, but I can't thank you enough ! Thank you

You’re welcome! :) I can relate completely to my mental state being directly related to the health of my reef aquarium... you are not alone!
