Elimi-NP Tropic Marine

Hi, this product can help to decrease No3 or only the Po4??

RamsReef · Dec 23, 2018

Both, carbon dosing increases bacteria which use no3 and po4 and carbon to grow.

It's best at maintaining levels in a balanced ratio more so than knocking high levels down.

Carbon dosing generally has an imbalance toward more nitrate reduction that phosphate due to denitrification reducing nitrate and not phosphate, although it drives other processes that consume both.

Elimi-NP is not the same as traditional carbon dosing. They incorporate some level of Po4 & NO3 so you don't get the imbalance or limiting factor. It's the same as their Bacto balance product which contains some trace elements. Elimi-NP is for systems with Calcium reactors so it doesn't have the trace elements.

I've been using Bacto balance for a year on one of my systems and there has been no imbalance and the ratio stays consistent. I decided to test it after tracking a system that had been using it for approx. 4 years.

It's not the product I would go to if either P04 or N03 were out of balance to extremes but it does a nice job of keeping these levels consistent at steady state.

How could a product know the relative amount of denitrification vs simple uptake in any given reef tank, and even if it did what you claim, why would one need or want to add BOTH N and P in such a product?

I don't claim it to do anything.......Tropic Marin makes those claims.

I'm simply relaying my experience with the product after a full year of use. I had the same questions as you just presented.

I tracked this tank for the past 3 years starting at post #50. He's had a lot of success with it.

Thanks. FWIW, I don’t see it mentioning that it contains N and P.

I never said it contains N and P..........it's possible my interpretation of what is communicated from the product isn't quite correct, so I'll leave that to others.

What is important though, is first hand experience with the product and how it performs and that it does in fact keep a balance in P04 and N03, which very few carbon dosing products or algae filters can maintain.

Anyways.........from the link, I'll let others interpret what this means---

NP-BACTO-BALANCE acts to increase the incorporation of nitrates and phosphates in additional biomass, reducing nitrate and phosphate concentrations in the water while improving coloration and growth of corals, sponges and other filter feeders. In this way, a nitrate and phosphate deficiency in the aquarium is prevented while at the same time the balance between these compounds is improved.

Ingredients
Tropic Marin® NP-BACTO-BALANCE contains organic and inorganic nutrients.

If @Hans-Werner wants to chime in he can explain more on this

Very little is needed and my current dose is tiny---

.4mls a day on a total 60g system. A 500ml bottle will last me 3.5 years at this rate. I dose that and have a skimmer and that's it.

You said. “They incorporate some level of PO4 and NO3 so you don’t get the imbalance”.

That is what I was referring to and which makes little sense to me.

My thoughts about this product was it was carbon source with maybe added Kno3 or Nano3 to put some weight on the Po4 reduction but i mailed TM asking & got told no.
Next thought was then maybe Lanthanum but i would have thought icp users would have uncovered that.
After tripping over a comment about another product i think PERHAPS it might be linked with this

I started using it a couple of weeks ago hence my interest
