Ahh that’s what I’m thinking will end up happening also once I raise the nitrate the phosphate consumption going up.. where did 50ml put you at? 5ppm?

Hey again ya’ll.

I’ve ran into an issue with my 150g, 0 nitrates constantly with the Hannah and NT Labs test kit. Phosphate around 0.05-0.1 not too worried about the phosphate as I don’t have any algae issues and coral does seem to be happy for the most part but I’m worried the nitrates not registering is going to lead to a decline eventually.. I had maybe 2-4ppm nitrate before I added a Chaeto refugium on a low light short photo period of 4 hours every other night. But then it zeroed out so I tried feeding heavier, skimming drier, removing the Chaeto all together, but it’s still at 0.. the next step I’m considering is reducing the bio media in my sump, currently there’s maybe 10lbs of rock and 4 polyp labs genesis rock which are rated for like 350g each so I’m sort of worried anaerobic bacteria might be too strong and breaking down my nitrates before they can register.. considering removing 2/4 bricks.
How old is your tank? Also, what do you feed specifically? I’ve found that frozen food is really necessary daily for consistent nutrients. I used Rods food daily for my tank. My tank is only 10 months old and I’m getting nitrates of 15 and Phos of 0.14 consistently now. It took until probably the 6 or 7 months mark before I finally started seeing consistent nitrates

It’s pretty new honestly only 2 months or so but I started it up with a lot of mature rock and media. I understand it’s not completely mature yet until atleast 6mo to a year. Specifically I feed PE frozen mysis and TDO chroma boost for pellets

Exact same. My tank is almost 9 months old and nitrates would disappear overnight at times. Started feeding super heavy and now nitrates staying steady around 5-10

Ahh okay thanks. I shouldn’t be too worried that going from 0-5ppm of nitrate will stress my goni’s/acros? My tank has a lot of frags right now but nothing is too huge except maybe my Trachy, lobo and symphyllia. Was watching a podcast earlier talking about the ammonium dosing and it said maybe for a newer tank it wouldn’t be the route to go. Thoughts?

I’ve not seen anyone noting a negative effect of a 5-10 ppm nitrate dose.

If you do not have corals, ammonia dosing is not a benefit over nitrate dosing. If you do have corals, regardless of tank age, then it may be. In any case, it’s like adding a fish so don’t stress over it as being risky.

Okay. Yeah I ended up reading it to be nothing but beneficial as you’ve said. Thanks 🤙 I’ll post results once I start dosing. I believe I should receive it this coming week.

I would NOT recommend dosing nitrates at this point. A new tank needs to go through it's own cycle without complicating things with dosing chemicals.
Just keep feeding your fish, add beneficial bacteria (I used Microbacter7) periodically and just be patient. It's way too early in your tank's journey to be chasing nitrate and phosphate numbers IMO.
Again, my tank didn't stabilize until it was like 8 months old.

Right I mean, I don’t see it at chasing numbers, but keeping nitrate from being 0 to prevent issues like Dino’s or coral loss.

The problem is that your nitrate is not truly zero. I would bet money that there is algae and/or other organisms living in your tank (probably on your rock work) right now that are using the nitrates up and preventing you from being able to detect it in your testing. I remember when my tank was 2-3 months old I had this layer of thin, fine brown algae on the bottom of my tank (it's barebottom), that stayed there for weeks, if not months. During that time my nitrates were always zero. As soon as my snails and fish finally rid the tank of that algae, that's when I started seeing my nitrates test above 0. It took months for that to happen.
It's really best to let nature take it's course. Your tank is too young for corals anyway. They won't thrive in these conditions, even if you dose nitrates. It's best to take a pause, don't add anything else, and let the system stabilize. Once you start seeing strong coralline algae growth, that's when you know the tank has reached some stability/maturity.
I also recommend running a strong UV sterilizer during these initial months to help combat major algae/dino/bacterial blooms. Continue doing beneficial bacteria as well. This really help with the ugly phases.

Agreed here….i’m yet to see an aquarium with fed fish that coral and biodiversity is so dense that nitrogen becomes limited. Po4, on the other hand, I have witnessed firsthand becoming limited. My aquarium where nitrogen requirements are large and exist even beyond the confines of the glass box is not nitrogen limited based on ICP testing and experience. Despite careful feeding, a moderate fish population, active filtration, and consistent maintenance my tank with undetectable hobby tested no3 is thriving.

I disagree, and think reducing the dino risk is well worth doing.

But of course that is the case in any tank of any age. Nitrate is what it is, and is always a balance between input between inputs and exports. Nothing about a new tank makes that fact any different.

Sure, but a new tank has lots of various stages of succession to go through still, all of which can cause dramatic fluctuations in nutrient levels. That's why I treat a new tank differently. Personally, I see dosing nitrate as a thing to do when you're trying to dial in perfect parameters on a mature tank where all other parameters have proven to be mostly stable for quite some time. I prefer the keep it simple approach wherever possible, but that's just me. My tank never got dinos during the early stages, which I think has to do mostly with oversized UV sterilizer use and regularly dosing Microbacter7. I did get a brief red slime algae phase, but was able to beat that with a turkey baster daily for a week or two and it never got out of control. The UV sterilizer did the rest and again, dosing beneficial bacteria.
I'll be interested to see what happens after the OP doses nitrates for awhile though. Should be an interesting experiment.

My concern with not boosting nutrients is dinos. I think that’s a worse possible problem than boosting other algae. It might or might not happen, but I would not risk it.

A little lower with my daily consumption….at first I was hovering around 2.4 and rising .1-.3 daily,
every few days would have a larger bump and then level off

I’ve been testing and manually dosing in the
Morning before work,
I started with 8-10ml at first and was getting 0-.1 nitrates max, I switched to about 50ml a day, 10ml of Ab+ and 1ml of phosphates
My high phosphates dropped and tanked after the third big dose of nitrates

That last sentence does not sound plausible, but maybe I am misunderstanding.

Phosphate dropped from what to what after a third dose of nitrate at what level?

Just applied my first dose of neonitro, 120ml 20ml per .5ppm to try and raise it to 3ppm. Tested about an hour later and I’m registering 0.7 nitrate as of now. Will check again tomorrow and dose again if needed.

Before I started dosing nitrates my phosphates were .2ish, once I started dosing nitrates my phosphates were consumed very quickly
Now I’m dosing both N and P

As long as you are checking once in a while with a reliable kit, dosing both is fine. It's just not typically the case that phosphate ever drops suddenly just because nitrate is increased. It takes a lot of nitrate to cause the depletion of 0.2 ppm phosphate. Maybe more than you have dosed.
