I've increased aeration and temp. I'm not sure what category eurythromicin falls into but thats the antibacterial medication I tried. Currently I'm on the second round with parasite clear. I added enough to treat a 240 gallon tank this time around and treated for 2 treatments as per directions. If that doesn't work I'll try the antibacterial meds again using a different type. Incidently its cost me over $100 so far not including the UV sterilyzer. I could easily just decide enough is enough but I'd like to get to the bottom of this so others can benefit from it.
