Tank set up for 2 plus months now, yes it's established. First fish (Tang) died weeks after it was introduced, after last water change remaining fish began to die every day ie blue tang, saebe clowns etc. There are invertebrates i the tank but no Sea Apples or Cucumbers. This does not make sense!

They only started dying after the water change? Was it treated properly? Correct pH and density? Weird that the invertibrates are okay. Could it be a killer fish? How are their fins? Color? Are any looking exhausted?
Just some checks...

Good to know you've checked those parameters. Are the fish gilling heavily? Does it look like they are hyperventilating? If so, your dissolved oxygen may be too low. Add airation to the tank and some surface agitation as well. This will help get oxygen back into the water and raise the pH. Is the salinity and pH range normal? You may also want to test the copper and chlorines in the water. Any water that is not DI (deionized) could have these in the tank. Although copper will kill your invertebrates immediately.
Do you see any lesions or or fuzziness on their skin surface? If you are sure your source water is ok, daily water changes will always help.

It relies upon how exact you want the suggestions to be. you may desire to purchase one among those kits from a puppy shop. you will get low-value, all-in-one try strips which you dunk interior the water and get a well-known examine (like this point is risk-free vs this point isn't). There additionally are man or woman kits for each style of try you want, and those are extra precise and contain taking a pattern of water and including chemical components, and the colour produced gives you a variety to furnish you a level (point) of a undeniable element interior the water. i individually use a try kit that has a determination of man or woman kits that require me to tug a water pattern out of the water. Saltwater fish could be particularly an investment, so i could purchase some coverage with a high quality try kit. I in case you won't be able to discover what you want on the community fish shop, look into bigalsonline.

My first question would be are there any physical injurys on the fish or do they end up in the overflow or just dissapear. Second is what type system have you got set up?

Have you put any decorations in the tank. I had a problem with a shipwreck reacting with the salt water and killing the fish.
