As for the osmocote, i added 12 capsules, three rows of four, along the glass before i added the gravel.
I wish i could just hand this over to someone who knows their ammonia stuff, but my poor tank is stuck with just me dealing with it.
Im about to do a 50% wc, on top of the 20% i just did. Ill test after that.
I am utterly exhausted by this...
