NOPOX daily dose

[chariton]

Hello I have a 580litres mixed reef and due to high phosphates (0.61 ppm) and nitrates(50 ppm) I started dosing NOPOX. At the beginning I started with 1ml per day for 2 weeks then 2ml for other 2 weeks then 3ml for the next 2 weeks and then I did a water change of 200litres I measure the phosphates(0.21 ppm) and nitrates(25ppm) and I went on on 4ml. Now I am on 10th week I tested today and I got the following

Phosphorus 87
Phosphate 0.26
Magnesium 1215
KH 7.3
Calcium 460
NO3 50
Salinity 1.025
Temp 27.5

I read the instructions again and I watched a Red Sea video on youtube that says I have to dose 2ml per 100litres or 3ml maximum. And my question is should I keep going up 1ml per weer or 2 weeks or I should go directly to maximum dosage (2ml/100litres). Also in my mind is when I finally lower them to reduce the dosage back 1ml per week until finally rich 1ml and stop NOPOX. I don’t want to stay on NOPOX forever. I only want to boost my tank to lower phosphates and nitrates and then keep them low with water change!
PS. 1)I test my tank every weekend
PS. 2)I do a 200litres water change every month
PS. 3)I have to increase KH I know!

Thank you in advance for your time.

I think according to the redsea nopox instructions you can dose up to 3ml per 100L so you should be able to max dose up to 17.4ml. But I would go slow and test as you go.

Also I wouldn't say your alk was low, remember the key is stability not necessary having the "correct" number

Perhaps review how much your feeding and what nutrient export methods you are using, are you using a skimmer or any type of chemical filtration?

I agree!
I use a nyos skimmer. Clarisea 5000 and yes I have chemical filtration.
Also should I take out antiphos while using nopox

Organic carbon dosing is most often used as a permanent tool, not a fix it and stop type of thing.

Phos up a little (.06 - .1) is a good range an alk can go closer to 8 however dont make a point of chasing these numbers if corals are doing well. NoPox can bottom out numbers at times and even promote dino.

What do you mean by type of thing?

Most corals doing pretty well. Except acroporas!

I mean it’s not typically a once and done correction. Some things are (e.g., raising salinity) and some things are not (e.g., raising alkalinity). Most folks do it long term.

I know it’s long terms I am trying the past year to lower them using water changes, carbon and antiphos. But I think my rock has the problem with the phos and that why I used nopox. In my mind is as less chemical as I can.

well, everything in NOPOX and everything else you can see is a chemical.

But on the specific issue of water changes, they work ok for nitrate, but are an exceptionally poor way to reduce phosphate. Organic carbon dosing like NOPOX is also typically not very effective in phosphate. Best bet for a significant reduction in phosphate is a binder such as lanthanum or GFO.

NoPox may be taking away the needed phos the acros need. I use it maybe 1-2X a week

I'm not sure, but do you think that it might be because his nitrates are at 50 since his phosphate is 0.26 and 0.3 is recommended?

 

[Uncle99]

After using Nopox ramped up to full dose for 6 months in 180g volume, it reduced nitrate from 50ppm to 5ppm. Once 5ppm was achieved I reduced the dose to 1ml per day for 4 months but it did almost zero out my nitrate. I’ve stopped it completely for 7 months now and nitrate stays pinned at 5-7ppm.

So for me, the long term use was not required, good thing as the stuff is a bit pricey, but easy to deploy.

IMO, it does very little with phosphate so I just mop that up with GFO.

0.3 is not recommended anywhere to my knowledge. 0.03 used to be a commonly reference target (maybe still is?) Now many aim higher, like 0.06 to 0.1.

I left out a 0! Thats actually what i meant
