Funny story that has taught me a valuable lesson. I changed everything fine and all the fish are fine; however my tank is upstairs and I needed to take down a big bucket of icky water to dump outside because my parents frown upon having it dumped in the bathroom plus I can then help fertilize the plants. So I had taken my phone upstairs with me, put it in my pocket and then was bringing the bucket down the stairs when the phone fell into the bucket of water and sunk to the bottom and now I don't know if it is going to work again so I'll most likely have to buy my parents a new portable phone. Lesson learnt never carry any electrical devices unless they are secured in a zip up pocket. Just thought I'd let everyone in on my stupidity.
