I don't know if anyone answered this, 2 suggestions.....
Whe I first started trying to grow plants in the 70s, I was trying to grow
a dwarf water lilly in a 29 gallon and kept getting nitogen spikes that
killed my fish. Because I didn't have a resource like this, I had to
guess, and finally figured out the the fertializer they were sending me
was urea based and causing the problem, I was burying a small amount of it
under the lilly when I planted it. Are you adding any kind of fertilizer?
I've also had plant leaves and rhizomes die and add to the nitrogen load
when they deteriurate, I once lost a tank of Yucatan Mollies in marginal
water conditions wnen the plants I added died and pushed the water over
Anyway- a couple of thoughts....
