How Often Do You Change The Air Stone And The Decoration/plasic Plants

[Renahastetras]

  Dear Tropical Fish Lovers!
 
  I'm wondering when do you change your air stone?  I just noticed ours not that bluish anymore, I washed it well, but it seems we need to replace it. Nobody mentioned to us in the store, I'm wondering how often do you do that?
Thank you

If cleaning my air stone doesn't make the flow of bubbles return to full I  chuck it and use a new one.
 
I change decorations when I don't like them anymore.  I use real plants though so, n/a.

I clean my air stones when they aren't putting out the amount of bubbles as they did when new. After so long, You can't clean them any longer and have them work so I just get new. As for decor replacement, I never change my decor. I add things, but keep everything as is. Some beneficial things can grow on your decor.
