Seachem Prime nitrate effect on DSB

i am pretty sure my dsb is not working, here is a link of the post where i asked about it.

but i have a new question after doing some thinking. from the above link you will now that my nitrates are 100+ and have been for a year. Is it posible prime works so good that it has starved the low oxygen bacteria, by making the nitrates not desireable for them to eat, hence killing them so the reason my DSB is dead. no gas bubbles any wheres, no worm trails. it just dont make sense that all other water parameters are perfect 0ppm but nitrates are way out. nothing dieing that i see

what inverts would high nitrate kill first, the pods/worms or snails/shrimp etc. or would it kill them all. i still have inverts thou not many worms/pods. is it possible the high nitrates have killed most of the worms making it so they are not in the bed, so theres no sand turn over, so the sand has compacted and the nitrates are in the bed with no way for the nitrogen cycle to work? seems far fecthed.

Q: How does Prime make a difference in reducing Nitrates?

A: The detoxification of nitrite and nitrate by Prime (when used at elevated levels) is not well understood from a mechanistic standpoint. The most likely explanation is that the nitrite and nitrate is removed in a manner similar to the way ammonia is removed; i.e. it is bound and held in a inert state until such time that bacteria in the biological filter are able to take a hold of it, break it apart and use it. Two other possible scenarios are reduction to nitrogen (N2) gas or conversion into a benign organic nitrogen compound.
I wish we had some more "concrete" explanation, but the end result is the same, it does actually detoxify nitrite and nitrate. This was unexpected chemically and thus initially we were not even aware of this, however we received numerous reports from customers stating that when they overdosed with Prime they were able to reduce or eliminate the high death rates they experienced when their nitrite and nitrate levels were high. We have received enough reports to date to ensure that this is no fluke and is in fact a verifiable function of the product.

super they dont even now how it works :. any ideas on how it may effect how prime converts the no3 and if the bacteria would still try converting it to nitrogen?

 

No one knows what prime does. It may interact with ammonia, and make it less toxic, or may just mess with the test kits.

If you are dosing prime, I would especially be skeptical of the test kit reading, as we don't really know what it does, we don't know how it effects certain test kits. It does effect certain ammonia test kits, and I wouldn't be surprised if it interfered with some nitrate test. Also, by the way, nitrate is not toxic, so, there is no reason to dose prime for nitrate. The issue with nitrate is it drives algae, which can be toxic, or can overgrow corals, or just look bad.

Here is some info on prime though, from a chemist.

Do you have algae problems?

 

no problum with algea, little grows on the LR but my fox face has kept it in check. i was told nitrates will kill inverts. if its non toxic and i dont have a algea problum then maybe the tank is just fine. any other ideas?
