help with using NOPOX

hello

i`ve started using nopox one week ago (8 days to be precise). my initial values were 0.75 ppm NO3 and 0.64 ppm PO4 (tested with red sea). i dosed 2ml/100l daily (my tank is 250l). now my results are 0 ppm nitrates and 0.08 ppm PO4. although i am obviously very happy with the results, i am confused about what to do next... how much nopox should i dose, considering my NO3 is zero?

please help.

thabk you!

Hi,
Reduce the dose between 1-2ml letting the NO3 build up a bit, the reduction of PO4 and NO3 is coupled.
You need to fine tune the dose allowing a constant reduction of both of them.
Keep testing once a week until you get it right.

All the best,
Aviad

Thanks for the answer.
Another question please: how do we know the carbons that we dose (contained in the NOPOX) do not build up in our systems? As I know, there is no way to test how much alcohol or vinegar we have in our tanks. Is there a risk of values going to high and affecting our animals, if the bacteria cannot cope with assimilating the carbon as fast as we dose?

Hi,
Great question!
The amount of carbon is very small(up to 3ml in 100l or 25gal), in case we overdose it’s still too little to cause any damage.
At the worst case you might experience bacterial bloom and the skimmer is going to take the excess bacteria out.
Simple carbons are valuable resources and are used almost immediately, so the chances of accumulation is almost non existing especially with the doses we work with.
Hope I helped.
All the best,
Aviad

dear Aviad,

It`s been some time now since i've been dosing nopox. no matter what i do, still my nitrates are at zero and my phosphates are at 0.08 -0.16 ppm. i don`t mind the zero nitrates because i don`t have any corals (just anemones which i feed often so it shouldn`t be a problem). however i do mind the phosphates because of algae growth. my question is: do you think i could use some form of phosphate adsorber together with nopox? my lfs guy says that if you use nopox with gfo it can make your water cloudy. is that true? are there any other solutions to reduce phosphates?

thank you!

Hi,
If your NO3 are at 0ppm and you still have PO4. It might be due to the live\frozen food you are using.
Try to cut back on the feeding or even feed the anemones with dry pellets.
Using NOPOX and GFO to treat an imbalance and high PO4 is possible but should be done carefully.
As soon as the PO4 levels drop to ~0.02 you should remove it.
Test PO4 twice a week since GFO works pretty fast...

All the best,
Aviad
