Sorry to hear this, have you been doing a gravel vac before redosing, what fish do you have as some can't tolerate high temp, clown loaches are funny with whitespot meds did you half dose with them, tank size would be good in gallons, plus water stats in ammonia,nitrite,nitrate,and ph.

Sadly the clown loach shouldn't of been in that size tank, i would go in with the full dose, the angel needs a 30gal ank, but it's not to bad, if they are getting no better i would increase the dose now the clown loach has gone to full dose, good luck.
