White spot

[Blue Tang]

Hello all again, I have got a tankfull of fish with whitespot Ive been having trouble with my nitrate levels and have done four water changes in the past four days to try and take a bit of stress off the fish, also i have used a product called tri Sulfa tablets, this im told is supposed to get rid of white spot but it does not seem to be working? can anyone help me to get rid of this white spot , the only thing is i dont have another tank to put my fish in and also i have corals etc so treating with copper or the like is out of the question , I need help please!!! My nitrate level is around 20-50 ppm and i cant seem to get it down.

what is that in your sump? live rock rubble? i'm wondering if it isn't that.

The two sectoins in the sump have coral rubble and on the bottom of the sump it is calcium carbonate.

i would shut down the return pump, stir that media around, and then do a waterchange in the sump, or two, if you see alot of junk floating in the water.
do you vaccuum your sand bed? obviously, the nitrate is coming from some proteins sitting somewhere. the only 2 places i think it can be is the sand bed or your sump media.
