Two simple questions that run counter:
Why do we ever get green water then?
Or why cannot we simply add progressively more and more fish load to supply our nutrient needs?
Simple questions right?
If NH4 is really not causing the issue, then what specifically is?
I can consistently add NH4 and get GW.
I can consistently add more and more fish and get GW.
If it's not NH4, then what is it?
I can add each nutrient, NH4 is the most likely candidate.
I think what's happening though is not really that counter to what I've seen:
Adding a little bit of NH4 to the substrate is not a large issues.
Adding a lot is.
Adding a little light, not an issue also, adding a lot, is.
Getting away with substrate ferts, TMG and lean N&P water column with lower light is possible with fish loading only.
Lots of large water changes will address NH4 dosing issues.
Many do these lower light, substrate ferts in new tanks.
ADA AS has NH4, so does PS( a lot more).
So does soil.
Folks have some issues until most of it is all gone due to bacterial oxidation and use Activated carbon/zeolite, water changes, mature filters(why might adding those to a new tank help after all? PO4? K+? cannot be CO2 or other things, O2? NO3? NH4?)
If adding NH4 to a tank works so well, why bother with aquarium fertilizers at all? Shouldn't we just use terrestrial fertilizers?
Why would pulling up a jobes stick or tossing one into a high light cause algae then?
Now adding a tiny amount of NH4 is likely fine to lower light well planted tank.
Since it's a tiny amount, it's not really going to a whole lot unless you have a lower light tank perhaps. If you add it namely to the substrate, the layer will settle and the top will be namely NO3 after 2-3 weeks and the bottom layer should turn anaerobic and be maintained as NH4.
What happens when you pull up a soil based tank in the start up phase(first few weeks)?
You can test and try it yourself.
Do not take my word for it
It's all about the dose and not the black or white add it or not mentality.
A tiny amount is going to have less significant effect, putting into a grain like the ADA product likely would help some plants. And outer grain will not have NH4, only the inside after a peroid of time, the roots will still be able to get at the NH4 lock inside the grain though.
As long as we have LOW DOSE of NH4, like fish waste levels(which tend to used ASAP and seldom if ever measured), there's little harm.
High light also makes a large difference.
Troopica is welcomed to offer an alternative explaination and also discuss specifics such as dose, light intensity, anmd plant biomass, water column levels and location etc.
But I can say adding a little bit of NH4 is obviously not causing algae also, most folks have fish after all.
I can also say why not use terrestrial fertilizers?
why have those not been successfull if what they say is really true based on the above comments from Tropica?
They would do themselves out of a business
Adding a little bit and saying it helps is a bit misleading.
If you add only a little bit to the
water column, it's hard to get much impact, if you add more to the substrate and have it locked inside, then the plant roots can get at it.
If you lock it inside individual grains vs a solid layer like soil, uprooting should not be such an issue.
There's a lot mroe it than the simplisitic explanation recieved.
I'm only hearing this 3rd party from Tropica(I know Troels and Ole, I do not think either of us saw any differences between what we talk about it about NH4)
