I have a fifty gallon planted tank and dose the complete seachem line. I added about 20 cherry shrimp last week and they seem to be doing just fine. I was worried about dosing the flourish and trace because it does contain copper. I dose the flourish with about 4.2 ml and trace 12.5 twice a week and do about a 40% water change weekly. Will the shrimp be ok with this? The shrimp seem to enjoy my driftwood that is covered with java moss and directly in front of a spraybar that is putting out my CO2 with lots of flow. All the fish in the tank leave them alone so far.
what about using a soulution like PPS or EI? I'm thinking PPS just because i've seen the #'s of coper induced over on PT and it's something like .000019ppm or something like that. I assume that would be fine?
