Your fish will most likely be just fine.

I have added new sand to an existing tank with the same results, fish fared fine, sometimes corals had an issue.

Running some mechanical filtration like sock, sponge or floss and expedite the clearing of the water.

 

thank you very much ill add on a small hob filter for now

 

their all good!

 

yay!
