Hi! I have a 75 gal SW
with crushed coral and lace rock.
We set the tank up on Dec 9th and when it was cycled we added a school of 8 blue/green chromis. Slowly, they are dying off (that's another topic
) We are down to 3 chromis now. We waited about a week after adding them and on Sunday (4 days ago) we added a Yellow Eye Tang and a Coral Beauty Angel. We did not QT
Last night I noticed they both had some tiny white spots on them (mainly on their face) so we treated with Melafix. This morning, they are both COVERED in tiny white spots. The 3 remaining chromis look fine.
We are using a 125 gal
wet/dry filter and the water parameters are as follows:
pH is 8.4 (recently it's been as high as 8.5 and as low as 8.2)
Alkalinity is normal
Nitrate just went from 0 to 20 the other day
Will the Melafix work? What else should I do?!?! I am new to this and am finding we made some pretty big mistakes starting off. This is quite frustrating and I hate that the fish are sick now. I hope they can be saved. Please help!!!
