Hi @JoshP12 Not sure I ever saw urea listed as an ingredient on Tropical Premium or Specialized? - it might be in there of course. If urea is such a potent/beneficial compound why isn't it used more in off-the-shelf aquatic plant fertilizers?A good question: Why is Tropica nutrition so awesome? Why do copy cats without Urea not perform as well?
Hey Michael!Hi @JoshP12 Not sure I ever saw urea listed as an ingredient on Tropical Premium or Specialized? - it might be in there of course. If urea is such a potent/beneficial compound why isn't it used more in off-the-shelf aquatic plant fertilizers?
I've used Tropica for years (recently and in the past). Good product, but expensive in the long run and somewhat harder to find here in the US. I completely switched over to DIY dry dosing NPK and a a liquid agriculture micro blend a while ago. seems to be doing just as well as Tropica did in my two heavily planted low-tech tanks.
Thanks for sharing your thoughts and insights.
Hi @JoshP12 OK, interesting. I might look into dosing urea separately.Hey Michael!
It is used in seachem, ADA, and Tropica.
Will only notice under more demanding species and with its use probably can get by with less co2 injection. In low tech, could keep “more demanding” species potentially than you could without. Or more stability etc. It could even be an observation of shorter internodes vs longer so favoured plant forms.
Kind of like adding glut.
well, didn't realize it would be a safety hazard ... well, maybe I'll skip this one And I am not really inclined to go back and pay money for commercial aquatic fertilizers.Personally, I won’t keep urea in my house due to MSDS (for the same reason I won’t keep glut or use excel in my tank).
I don't want to bias you from making personal decisions. Many people use gluteraldehyde and also Urea-formaldehyde in their homes.well, didn't realize it would be a safety hazard ... well, maybe I'll skip this one
@JoshP12 Thanks... yep, I've seen other people here mention Miracle Gro... I should be able to find it on amazon. I'll have to see how it will factor in with my current Macro and Micro dosing.Miracle Gro slo release in gel caps (all natural - I’ve used both animal and vegan - from health foods store or online).
Roll ‘em up, plunk ‘em in!
They are potent.
Hi @JoshP12 Thanks for the additional info. I will try it out. I am not really too worried about any downsides with over-fertilization - as long as it wont jeopardize the livestock of course.Its like an additional investment. Just put them in the substrate and they act as a reserve to top off water column (via obeying leidbig). So if you don’t dose the column, the roots can access nutrients from substrate. It is a very effective tool as the plant can virtually choose what it wants from the substrate, instead of being fed through the column. So if your availability (whether demand or acquisition) is off for one of your species, it can probably just top itself off from its roots. The ultimate is basically doing both -- feed the column "the basics" minimally, then let each of your poorly picked species (since we pick for selfish reasons often lol), struggle to adapt and give them a buffet in substrate.
Right. I already routinely have 20-40ppm of NO3 and 20ppm of PO4 and probably around 80ppm of K.My pleasure.
Livestock isn't going to care too much for nitrate and phosphate levels unless you don't change water for months. I think I linked some studies in some thread somewhere -- it was like 100ppm of N (which means more Nitrate) . Certainly, if you lard in micros to crazy levels, those metals could very potentially get your fish, but not in the concentrations EI prescribes.
Agreed...I was mostly thinking along the lines of hitting limits for the livestock, which are arguable very high for all the Macros at least.Intuitively, I think I understand what you mean about over-fertilizing; though, I am not sure this concept exists.
I assume it is because of the potential issues with ammonia (NH3).If urea is such a potent/beneficial compound why isn't it used more in off-the-shelf aquatic plant fertilizers?
I'm still using the liquid formulation of <"Miracle-Gro"> and I know that @Zeus. and @jaypeecee have experimented with urea dosing.Miracle Gro slo release in gel caps
It is an American product so I would expect that you can find it stateside.mention Miracle Gro... I should be able to find it on amazon
