How can we know that if we are not measuring this? Are there indicators?Bacteria may also prefer ammonia over nitrate. I don’t believe ammonia starvation is likely. We aren’t dosing carbon to the point where the water is thick with bacteria slime. Everyone has a fair shot at getting ammonia.
Yes that could be an advantage ....Many corals can also make do with nitrate. The corals can also capture bacteria, so starvation in a high nutrient tank with carbon dosing is unlikely.
Is the approach of tropic Marin with there Bacto Balance not the best way to go? Making a mix with the needed trace elements and a small amount of nitrogen to backup this process?Yes, we do. I wonder if the people that don’t find carbon dosing effective are deficient in some trace elements. It can’t hurt to dose a little and see if there’s a response in the nitrate reduction.
I doubt this. 99,9% of the mature tanks are not measuring this parameter. I have a 650 liter sps tank (age 7 years) with carbon dosing as a tool. A few months ago I raised the dosage and instead of going down with No3, I went up. After reading a few threads on this forum (Thanx @Lasse ) I figured out that my tank was producing nitrite ..... Was this the start of the change or was this already longer the case? And was I making assumptions based on wrong No3 numbers in the past. ICP doesn't gave answers when this is the only tool in combination with the "home" no3 test kits .....Testing nitrite is a good idea when nitrate tests are unusually high. Though, I think detectable nitrite is pretty uncommon in established tanks over 6 months old. It can’t hurt to check, especially if the NO3 readings are off the charts.
And what is happening in my tank? Is No3 acting as an reductant (ending with No2) or am I boosting a incomplete nitratifiaction process with carbon dosing stimulating only heterotrophic bacteria?
