Help. Ongoing issue affecting some fish even in quarantine.
Firstly lost a few fish 2 months back from DT to what I thought was a bacterial infection - got them out of tank and into quarantine and those that came out seem now ok but any new additions to quarantine struggles within a few days or dies. LFS have tested everything and everything is good. Alk is 8.5 - temp 25deg - salinity 1.008 (hypo) no corals. They confirm my results. Oxygen reading on Salifert is 8 have big skimmer in, air stone and 2powerheads pointing to surface Ona 100l frag tank shape. Quarantine established a few months.
Now Again running another round af AnTi Biotics (Furan 2, kanaplex, focus, metro) also got neoplex and sulphaplex also adding ginger and garlic to food.
Ordered a Hanna kit so I can be very specific and run copper.
At present the fish effected are
Pink skunk clown (the male -female is fine)
Lost a golden angel within 4 days last week (salinity was 1.016 at the time) didn’t have any lumps but seemed to get a “sheen” on him LFS said he had no slime on him when I took him ( he was still alive and they quarantined him for the last day for me) they took a yellow tang who was starting to show similar but he pulled through...
Gold back is not wrasse not to happy
Solon wrasse not good breathing affected
Was running ozone but have now turned it off
Couple showing white stringy poo but the only visible mark is this on the clown......
Obviously stopped eating.
Any ideas? Thanks
