new sand?

Would it be a bad Idea to replace all the sand in my 14 gal bio cube? Its not really dirty I clean it on a regular basis while doing water changes. The reason I am wanting to do this is because I have little pink things all in my sand making it look not how I want. Also I want to get rid of spaghetti worms. I have way to many. Is there anything that eats them they are all in my live rock its annoying me.

 

most wrasses eat them and also bannded coral shrimp

i just put my new wrasse in and he went to town on them

 

ooo alright I'll look into that thanks! that makes a lot of sense I had a wrasse but he died and now they are just out of control.

 

If your using live sand and the aquarium is established. I would not reccomend it unless your going to cycle the tank again

 

Im not gonna cycle it again I will probably just add a bit more sand. Mine isn't deep at all.
