to be honest i have no idea what my water parameters are, never tested, seachem tang buffer & prime to the recomended dosage, she'll be right
I'm similar here but my f1's do have two Dom males in the tank all ready no loss's, but the first few days had a couple getting beaten up but that seems to of cooled off, I feed everyday with a auto feeder doing my job when I'm not there. As for water wise I keep it about 8.2 ph an a KH of 10-14 with salts and 40% water change each weekend
