I'd suggest getting the nitrates to below 20ppm by doing a 50% water
change.

Also try melafix - its natural and good for healing wounds and split fins
and won't destroy your bio filtration - although thats probably gone now
cos your chucked all the old media away.

Have you seen any real data on Melafix? All I can find are anecdotes
and people confused about tea tree oil. Please point the way if you've
seen any studies.

Nope but I've used it successfully. Small doses also helped me raise Fry
with less deaths than previously.
