Before reading, please be forewarned that the following content contains some seriously stupid moments. You should be prepared to laugh and also to ask yourself, "what the h-ll was Lloyd thinking?". I fully expect to be laughed at on this one; self-effacing humor is sometimes the best kind of humor that exists, so please fire away. I have my flak jacket on.

I was reading through some R2R posts about AA's and ran across an old thread by the good Rev himself, @revhtree ; my story is after his question and comment from 2012:
We are going to continue discussing the reef aquarium facts submitted by our members. Do you agree or disagree? What are your thoughts?

Fact #92

Do not overdose amino acids unless you like algae.

Truth or False? What else might we need to learn on this subject? Please also share any pictures that may pertain to the subject. ;)
\

OK, this a SUPER old thread, but I wanted to add something here which I had to learn the hard way. Overdosing AA's doesn't just cause algae. AA's seem to be relatively benign, right? They are the building blocks of life, so on and so forth... Since AA dosing is becoming more popular with so many good product lines available, I wanted to share what else can happen when one overdoses AA's...
A bit of background, I run a 40 gallon total system volume nano tank. RO skimmer, biopellets, a lot of LR, especially in sump, chaeto in sump, and that's about it for major things. Everything was going great with the biopellets. Undetectable levels of nitrates, PO4 running consistently at about 0.02 ppm, pretty heavy feeding and bioload, pH 8.3-8.4 during the day, 8.2 at night, no algae, no dinos and no cyano (though I had a dino problem when I started using biopellets). I also use soda lime in a BRS universal air filter connected to air intake of protein skimmer to counteract the CO2 and consequent downward drive of pH from the use of biopellets. Alkalinity seems to get used up pretty quick by the biopellets; I usually add Reef Fusion part 2 to keep alk at 7.5-8. Magnesium also gets used up, but I dose that as well to keep mag levels at 1300-1320. Calcium levels are generally 420-440.
So after doing some research and seeing what results people were getting from adding AA's to their tanks, I decided to try it out. BUT, instead of buying a known brand, I decided to buy a liquid amino acid supplement that listed all of the AA's they had in solution as well as everything else, which was little more than sodium chloride and water. If you want to look it up, it's Bragg's AA's. I don't have anything bad to say about them. I have to say that it evoked an immediate reaction on one of my micromussa, even with lights on it puffed up, tentacles came out and I could actually see into one of its mouths. I thought, "Sweet!" Let me just add a little more. I had done research and found that corals are actually quite well adapted to sensing AA's as well as uptaking the AA's. Quick rundown on that: although most corals do not need AA supplementation as they produce AA's themselves, and their zooxanthellae convert sodium carbonate via photosynthesis into AA's, then translocate those AA's to the host corals (verified through genetic sequencing which shows that zooxanthellae possess the genes for producing translocator proteins), corals can uptake AA's directly from the water column, and do so quite efficiently as well. So through direct biosynthesis, or indirectly through zooxanthellae, as well as feeding on plankton, which is another source of nitrogen uptake, corals can acquire most if not all amino acids. However, as stated above, corals can uptake AA's, which happen to be present in NSW at concentrations of 0.2-0.5 µmol/L, and moreover, this uptake can account for greater than 20% of corals nitrogen uptake. However, AA uptake rate increases by 6X when the total AA concentration is artificially raised to 8 µmol/L.!!
SO, being the super smart idiot that I am, I ran with the idea that, at least to a coral, if a little of something is good, then more is even better!! Hmmm. Bad life decision that one was. I did some math, and to figured out the weight of each amino acid per mole, then added everything and converted it until I could get to a total concentration of 8 µmol/L, then added that amount in grams, etc. Well, that was a lot of AA's and in looking back, my math was only incorrect by an order of magnitude. :mad: The issue of O/D'ing my tank on nothing more than 1970's hyped up health foods was compounded by my skimmer going crazy the night of the event and spilling everything over into my tank, including the heterotrophic bacteria that sucked up as much oxygen as possible and poisoned my tank. That sucked bad, no pun intended.

Getting back on track and with further brevity in mind, I dosed at night with lights off, woke up to a white cloudy tank, realized that I had a bacterial bloom and started mixing water. Changed as much as I could, but as you guys know, it made no difference. By the time I had walked back to my tub of salt mix, the little b@st@rds had multiplied again. So then onto checking parameters... Everything OK, not a trace of ammonia, so I thought I had escaped the worst. That was yesterday morning. By evening, my ammonia levels were higher than 8, no kidding. Nitrates at 5. Freaking out, and did 100% water change. Woke up to meteor shower cyphastrea RTN'ing, some SPS already fully RTN'ed; ammonia at 2 though and nitrates through the roof. Another W/C, but not 100%. Ammonia down to 2, nitrates down to 5 from close to 100. I just did an 80% W/C before writing this and ammonia is down to 0.25 and nitrates almost 0 but not quite. BUT, on a good note, there were no fish deaths. o_O

I'm not sure what the moral of the story is except for don't use non-reef safe anything, don't overdose anything and most importantly, please buy a Davy Jones Skimmate Locker from @AVAST Marine !!! One of those would have saved my tank, or at least, a skimmer that is going crazy into a DJSL might have mitigated the problem.

From a chemistry perspective, I understand how heterotrophic bacteria utilize AA's, but what I don't know is why such a high level of ammonia developed. There is no ammonia listed in the ingredients... I thought that the heterotrophs would utilize the carbon and the nitrogen present in a hefty dose of AA's. If that is the case, could such a high level of ammonia result from a massive die-off of the heterotrophs when their food source runs out? If not, and the heterotrophs are using the carbon present in AA's but not the nitrogen, or at least not in the C-N ratio present chemically for AA's, does the extra unused nitrogen get converted to waste as ammonia? I just don't get how I had such an incredibly high level of ammonia...
Additionally, did I compound the bacterial bloom by using biopellets? It seems that the answer to that is yes, since I am essentially cultivating the little critters in a reactor and when the bacterial spillover event occurred, millions of ready-to-reproduce critters (that can double every 20 minutes under ideal conditions, which I served up on a platter) emptied into my system. Alas, the lack of the DJSL...
What would you add @Randy Holmes-Farley ?
How careful do we truly need to be when dosing AA's? I would like to try again, lessons learned, but am wary of using AA's. I know that corals will use AA's, but I'm just not sure that they need to use them.

Thanks for listening...
Lloyd

Once the bacteria have consumed enough amino acid to satisfy their nitrogen needs, they may keep metabolizing the amino acids for energy. If you are metabolizing amino acids for energy, you will get ammonia.

How much amino acid did you add?

Dude, anyone who has been in this game for any length of time has done something that in retrospect was not a good idea. Hope you get a full recovery. Lesson learned.
HAHA! Man, that's the truth. Seemed like such a good idea at the time. I hope everything recovers, although the meteor shower cyphastrea looks like a goner. All the tissue reminds me of a really old tshirt full of holes, with more tissue being "torn" off the skeleton by the hour.

Ok gotcha. Thanks Randy. Is that because when metabolizing AA for energy, an [amino acid] dehydrogenase cleaves NH3 off of the AA to produce NADH? It's been a long time since undergraduate school.

I dosed 59 mL of total solution, of which 30.68 mL by weight is comprised of AA's (Alanine, Arginine, Aspartic Acid, Glutamic Acid, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tyrosine, Valine)

Certain amino acids when in excess can be broken down into carbon sources, especially when cellular requirements for amino acids and nitrogen are satisfied. When the amino acids are broken down, the nitrogen (amino group) must be disposed of somehow. Typically enzymes called transminases or aminotransferases can remove ammonia from the amino acids, and then enzymes involved in glutamate (a major sink for these amino groups) metabolism may release free ammonia/ammonium.

Great info @toaster77 ! OK, that's where glutamate dehydrogenase comes in, during the oxidative deamination step, correct? I'm hoping that something stuck 20 years ago...
By the way, welcome to R2R toaster! What do you do? How are you so familiar with biochemistry? Thanks again man

FWIW, if you google amino acid metabolism or catabolism in "images", you can see lots of flow charts that show where in these processes ammonia is released. :)

Thank you Randy. I already have googled it and it's quite apparent what happened.

In answer to your second question, I should have phrased it differently. The manufacturer provides the amount of protein per 5 mL, which is 500 mg. I dosed 59 mL, or ~6000 mg

Bragg's liquid "amino" is not something i'd put in my tank. From what I've find googling it seems that it is soy beans hydrolyzed with HCl and then neutralized with some bicarbonate, so it could be many things aside of amino acids in it.

Yep, not something I will do again. I looked into that and the only things left from hydrolysis of soybeans into AA's is salt and water: 2HCl + Na2CO3 ===> 2NaCl + CO2 + H2O.

The reason that I tried it was because I knew the ingredients, and I don't know what they are in any other supplement. Even MSG is sodium and glutamate, which is a common amino acid.

Either way, lesson learned. No more dosing of anything not meant for a reef until I understand the chemistry. :eek:

Studied it in college and still work in the field now... :)
Most of your thought process and reasoning are right on target, except the math error. Good luck getting the tank back in shape!

Thank you for that feedback toaster! Makes me feel a little bit better to know I was on the right track from a thinking perspective, just got too far outside the box on this one. Math errors drive me crazy; I should have known better. I was in bed at 2 AM using Notes on my iPhone to write down the calculations, and I didn't check my math again. Oh well, lesson learned on this one. For now, I'll stick to methods known to work, even if the manufacturers don't list the formulas for their products.
Even after 5 massive WC's of at least 80%, I am still registering ammonia at 1, and this morning noticed that some tissue on a favia appears to be STN'ing; the top ridge is turning white, but it's not tissue color change, it looks like loss of tissue, so I'm headed out to buy some Prime to bind the ammonia, just to keep try and stop the progression of damage caused by the high ammonia. It's funny (stupid may be more appropriate) that I did not even think to google metabolism of AA's. It would have been obvious what the end result would have been.

Any thoughts on using Prime? I've never actually used it in a tank with inhabitants in it, and have not used it in a system for a long time. Any thoughts on using Prime to neutralize the ammonia? What are the adverse effects of Prime to corals and fish? @toaster77 , what are your thoughts? I feel like I don't have a choice at this point. I know the ammonia will be converted eventually, but my corals may be dead or too severely damaged by then... I've never had an ammonia spike like this with inhabitants in the tank...

Awesome! Thank you Randy! Do you have a preference for one over the other, aside from the concentration of Prime? Any advantages to using Amquel? Or Amquel+?

Hopefully Prime does its thing quickly, or at least keep the effects of high ammonia from affecting more corals. Lost alien apple favia colony, or will unless it can rapidly regrow tissue back over exposed skeleton. First to go was meteor shower cyphastrea, also lost a small Hulk lepto colony, neon orange/blue/green Florida ric dissolved, birdsnest had finally started to take off but just officially crash landed, Acro super blue tenuis is crashing, but have a pretty green candy cane frag and a healthy platygyra, zoas are closed but not melting and indestructible palys are actually open. All euphyllia are closed but not dead yet and duncans just look ticked off. Darwin micromussa looks great. Condy looks good; hope it stays that way. Has anyone smelled a dead or dying nem? Makes me lose it..
This kind of stuff makes me want to quit, especially since it was my fault. im not going to, I love this too much but if I could physically kick myself I sure would. Depressing that 4 days ago I had a beautiful tank.
Anyway, if anyone that is thinking about dosing AA's reads this, just make sure that you do it right...:mad:
