    UV Sterilizer advice

    Back yet again looking for advice....so here is the situation. I'm moving to a community in Newfoundland where I have a endless supply of clean unpolluted natural sea water. There are several aquaculture operations in the area so I'm hoping it is a good source. I am in the process of setting a simple system up with a 3x turbo twist uv sterilizer, the necessary pumping and two rubbermaid 46 gallon containers set up in contionous loop. I hope that this will kill the bad stuff in the NSW. I was going to add about 25 to 30 pounds of live rock to the tubs to conteract any die off. Also 2 heaters will be used to get the water to temp. The water sg is 1.022, so I now I will need to add some salt mix to it. My big question is will a week of constant flow through this setup be enough to kill any of the bad stuff so the water will be safe to add to the main tank?
    Thanks in advance.

    In my opinion, you are probably safe to add the water directly to you system. I'm not sure I would do it, but, probably safe.

    By running it through a UV sterilizer, you are reducing the risk BUT killing any phyto plankton, etc. that you might have gotten for free. You should also be killing off bad living things too.

    You might consider running some carbon too, to help react out anything else that might be in the water, like pollutants from local boats, etc.

    You could also contact one or more of the aquaculture operations and ask if they have concerns about anything in the water.

    Again, my opinion, so feel free to ignore.

    Thanks for the advice. I forgot all about the carbon. I tried to contact the local aquaculture operations to see about water quality and they were pretty tight lipped about it. They just said they have no problems. Not sure if they knew what is was talking about or not. But I know the government inspector so I hope I can get a water quality report off of him. Keep the advice coming.

    All natural sea water that is added to the setup should be put through a UV or other purifying system. It is the smart and safe thing to be doing. However ... do this will reduce the benefits of using fresh sea water. The only way to struck a balance between good fresh sea water and SAFE sea water is to QT the water for the required period. IMO it is not the critters in that water that you need it is the chemical makeup that you want. This being the case I would mechanically filter it, UV it once at the right rate, heat it to correct Temp, test it and use it.

    Just like anything else that you would put in your tank that is taken from the wild .... 6 weeks QT. So you would need to be 1 water change ahead so to speak. If your doing a monthly change you will need 2 containers with a 2 week overlap.
    Many natural sea water suppliers will have already "cured" the water they sell.
