So my one turtle tank is being torn down and thoroughly clean since the turtle that was in there passed away to a bacterial infection; Sepsis. My plan is to drain tank, take out old substrate, clean whole tank with vinegar (water spota), clean canister filter, throw out filter floss/bio media. I was planning on keeping the coarse sponges though but wanted to know what's the best way to thoroughly clean these so nothing could be on them to play it safe. Should I boil them? Any help I appreciate!
