Hello from the Uk I am really glad to have found you. I have visited some other sites but not registered as they seem to talk in mumble jumble. This is a clear and very useful forum, so well done to all those who make it that way. Many years ago I used to keep a freshwater community tank, but had to give it up as life got in the way. I have now had to stop work as I suffer from depression which at times is very debilitating. I was given a lovely tank and stand after mentioning it was something I would like to do again. I am not in any hurry to get it set up as I know how to set up a good healthy tank, time must be spent in preparation. I haven't decided yet on what species I want to keep and I am currently researching my options. Now, I have this lovely tank which needs a really good cleaning, but I am worried that at sometime it might have housed rodents. Is there any special care I need to take in cleansing it? Is there a proprietry fish tank steriliser available. I am really looking forward to getting to know you all and to learning from the vast range of experience here on this forum.
