Hi, I have a PB tang ( and fox face and gold face goby) on day 3 at 2.0 ppm of copper power ( already did a 9 day treatment of GC* kanaplex + furan-2). Ramped it up over 8 days. Also started metroplex three days ago. The powder blue hs visible flukes in face (he’s pretty good at scrapping them off his face... eats well, colour is good, etc). Question is, what should I do: 1) stop metroplex and dose with prazipro and keep copper power stable; 2) stop metro and copper and do prazipro then start 30 days again with copper power and metro; 3) start prazipro and keep doing copper power with metro.. i.e., do all three and aerate heavily; 4) something else? Thanks!
