    i was thinking the other day.I am dosing kalkwasser into my tank to get my coralline algae growing.Now i live on a farm and we use borehole water which is very high in lime so much so that our geyser needs to be replaced regularly from being silted up with lime.Now would that water be safe to use in my fish tank or not or shouldnt i take the chance.

    Very interesting, if you could get it tested - professionally - it might prove pure enough, but it will have many elements in it that might cause you problems.

    dont even bother.....i can gaurantee it wont be anywhere near good enough to use in your marine tank.....
    the bad news is lime destroys reverse osmosis membranes too......
    so you would either need to buy r.o.water from a reputable lfs or install an expensive water softner to you house and then add a r.o.unit

    I would not use any other water except RO because the TDS is too high. Not all borehole water will be the same, but tested it once and got a TDS of 400 - 600 over a few days. Not good for marines, mineral water is not even good enough as some of them has a TDS of 90 - to not even talk about rain water full of toxins from insecticides and exhaust gasses.

    If that was only due to calcium and magnesium that would actually be very good, but, as previously stated, the borehole water probably contains many other elements (fertilizers and poisons being washed into the ground water being two possible problems...) which will build up over time, and will cause problems at a later stage.

    I agree with Mike, have the water analyzed professionally, and then make an informed decision.
