Sooo I am very excited to say I am in the process of buying my very 1st house. I have been renting and I'm ready to make the jump. I am making 100% sure my new house is reef friendly. My question. The house we choose has well water and the owners before us had lots of junk cars on the property. I think they might adversely effect the well water. What should I test for to make sure its safe for the people and the fish? I do have a 5 stage RODI unit I will be taking along but I want to make sure nothing crazy will be in the water ie: mercury , lead, benzine, hydro carbons, gas etc. This is a experienced homeowners questions and a reef question wrapped into one and I trust you guys will probably have the answer!
