huh? You have ammonia in your tap water? I wouldn't drink that if I were you.I think it's the explanation for the excessive pearling straight after a water change, with the plants going crazy for all the (detoxed with Prime) NH in the new water from the tap. But as that article says, it's all gone within hours.
Not so.....Tom Barr has been saying that for a while now, how the plants will use NH first if it's there before using NO3.
Yep, I've never seen any growth differences in an aquarium.Not so.....
In this thread, discussing the same article as a matter of fact, Barr says....
"The graph shows that NO3, not NH4 is preferred under our plant tank conditions."
Kekon from APC has been doing some cool experimenting with Urea, I am also adding Urea to my tank with no side effects. I dont know that i am seeing any benefit so far however.
BTW, I estimated using mass balance ratios for NH$ uptake rates max per day, I think I came up with a max of 0.8ppm of NH4 per day max usage.Thanks for the info Tom.
Currently i am adding about .5ppm of urea a day at one dose. Really the goal is to not provide faster growth, but larger growth(leaves/whirls). So far i have not seen much in a positive or negative way, but i just started....so a few weeks of consistency is in order before i am comfortable saying one way or another. I will certainly report my findings after i am done.
