no3

I have a Red Sea Reefer Max G2+ 300 tank that cycled well (fishless with Dr Tim's Ammonium Chloride Solution), spiking nitrates up to 75 at the end of the cycling. I have added cheato in the sump bringing it to 10 ppm. All is going well. I have slowly started with some fish (3 gobies, 1 blenny...

so on my quest to raise my nitrates I have upped my feeding. I only have two clowns and a hermit clean up crew. Feeding half a cube of frozen mysis daily. loads are left uneaten. Cuc do what they can. GHA is speeding up and nitrates haven’t budged. do you think I just need another fish ? Tank...

I have a question about NO3 and PO4 chemistry. Usually when PO4 drops NO3 would drop with it right? I've been having problems keeping PO4 up, so far I removed pellet reactor and disconnected the refugium. But as soon as I turn the fuge back on the PO4 drops too fast, is it possible that the...

I made a large water change today, and thought'd it be "fun" to compare results between the new Hanna Nitrate High Range 782, and the old Low Range 781 using the dilution step. 781 Low Range diluted 782 High Range Percentual Difference Before Water Change 24,9 33 27,9% After Water Change...

Okay everyone I have run into an interesting and difficult predicament that I think I need more information on. So I have two tanks. Let's call them Tank 1 and Tank 2. Both tanks have been running for one year, both tanks have their own filtration systems with exactly the same equipment, and...

I have measured few times NO3 with de New Hanna HI782 and I'm seeing that the values are much higher than the Salifert and Nyos checkers. Hanna HI782 --> 15.9 Salifert --> 9-10 NYOS --> 10. Is somebody experimenting this behavior?

So up until a few weeks ago I was battling high phosphate levels 1-2ppm, nitrates never rose above 10ppm, usually were at 5ppm. In an effort to lower PO3 I reduced feeding to once a day, that helped a little, got down to .5ppm. After a few weeks of that I decided to dose some Fritzyme 9 and...

I've been battling some cyano and turf algae pretty much since I've been in the hobby 2 1/2 years ago now. About 18 months ago I thought I found the end all solution...that being the Zeovit system. Ever seen then I've been running the full system (Zeo Stones, Carbon, Zeobac, Zeostart, ZeoFood...

What is the maximum nitrate reading you know of where corals were kept successfully? What is the “breaking point” for the hardiest of corals? What corals are the most tolerant to high nitrates? Please input especially if you have large predatory fish! Thanks!

OK, so I've been battling high NO3 & PO4 for a couple of weeks now. I've read almost every thread with the same issues, but I can't seem to get any subtle changes for the better. I'm at a loss for what to do. I'm not looking for a quick fix, but I'd love to be able to see *some* changes for the...

So, we've been trying to reduce PO4 slowly (started the whole process with 0.8) to get more coloration out of our SPS. We actually have a lot of great growth and no algae in our system, which we've been very happy about. We are currently running ROWAphos and Triton Carbon (2 cups each) in our...

What an ICP-OES machine CANNOT test As the company that developed the method for sea water analysis and making broadband testing available to aquarists, we at TRITON often get asked what an ICP-OES machine CAN test. These days it is getting more and more confusing with the proliferation of...

Hello everyone , I have problem with no3 it’s 40 . Changing water do not make any difference. I hear about using vodka, does anyone have any experience with using vodka to help ?

Hello! Over the years this has been one of my favorite subjects. A while back I noticed my tanks doing a lot better with more NO3 than PO4. When the NO3 matched the PO4 on the lower side the tank begin to grow hair algae in the sump, and dark brown algae on the rocks, overflow box, sand-bed...

Excuse my ignorance but is potassium nitrate or sodium nitrite better for dosing N03? If you could explain your answer too please since I’m not a chemist ;)

I need to dose No3 since it is consistently low. When buying Potassium Nitrate what should I look for? For example food grade/pharmaceutical grade etc

I think my tank suffered from lack of nitrates. I was dealing with some GHA and always testing zero for NO3 and PO4. I think my nitrates were actually too low, but the phosphates were used by the GHA. A few weeks back I dosed a few capfuls of Seachem flourish nitrogen over a few days, but then I...

Hello, I'm confused and can't seem to Google my way out of it. My Nitrate Pro test kit says "N-NO3 Nitrate Pro" on the top and comes with 3 dropper bottles of liquid reagents. I went to order a refill and found only "NO3 Nitrate Pro" kit refills, with one liquid dropper bottle and two vials of...

Hi Randy, and other Reef2Reefers. I have a problem that probably most reefers dream about having. I seem to have really low No3 and Po4 levels that I struggle to keep from bottoming out. I dose NoPox in a moderately stocked mixed reef 350 Reefer, at the level of 1.8ml daily, and maintain No3...

Hey guys, Am wondering what are the solutions or ways you have tried to successfully reduce NO3? I have been doing frequent water changes but the Nitrate level still hovers around 60ppm. Tank has been running for 9 months now. Was thinking of adding in SeaChem Stability and SeaChem Matrix to...

@Randy Holmes-Farley Do I need to start over from scratch if I am converting from NoPox to Vinegar? I can't remember how much is my dosing (ml) for NoPox ... I think 6ml per day if my memory serves me well ... I set and now forgot about it LOL but I can see the dosing container is thinning...

It seems that the hobby drifts towards and then away from the ultra low range nutrients systems on a regular cycle. It leads the 'newbies' (of which I still believe I am one) to the incorrect initial conclusion that you need 0 Nitrates and 0 Phosphates. I have a mixed reef and endeavor to keep...

To combat a surge of nitrates I have recently been dosing NOPOX. So far I have been seeing results, but also remembered I currently and running purigen in a reactor. Will these 2 compounds clash at all? I am seeing results, but I would like to min/max this process and not strip any chemistry...

Abstract: A calculation error led to the overdosing of tri sodium phosphate (TSP: Na3PO4) to a 700L (135 gallon display plumbed to two 25 gallon frag tanks) mixed reef system with deep sand bed that has been operating for the past 14 years. The overdose resulted in not the targeted 0.010 ppm...
