I have a question as far as the IBCs go. I am planning on setting up a tank for a research project for school. There are a few IBCs laying around my farm and I was hoping to use one as my tank. The problem is they were not used for holding foodstuff, but instead for fertilizer. I was planning on scrubbing with dish soap, then pressure washing it. I don't want to go through all of this trouble if there will still be any harmful chemical remaining that will hurt my fish. If adequately cleaned, will this plan work?
