I will see about photos when I do w/c. I NEVER washed out tanks with soap! Or tank decorations. But the little glass bowls Ive used to presoak food and dislove salt and as changing bowls where washed with Dawn when I first got them, which was anywhere from months ago to last year. Ive done a lot of water only rinsing since. I never used a thermomter in the new w/c water. Didnt think they would regester that fast. I will try it! I got a new one yesterday for Chloe but havent opened it. I can just use it. So I have the suctioncup in tank therm. and the outside thin strip ones. They vary about 2* , the outside ones always reading higher. Should I stick with twice a day feedings or try 3 times a day?
