    Hope someone can advise on this - I noted that the water in my garden pond (holding 5 goldfish) test 0 ppm for both Nitrite and Nitrate. Was now thinking - can this water replace the RO water I buy for my marine tank? (after red sea salt has been mixed into it).

    Just to add - I only top up the water in the garden pond, which is crystal clear.

    what do you top up the water in your pond with? indirectly you are putting that water in your tank with the living organisms of your pond in it which would die in your tank and cause an ammonia spurt. due to decoposition.(my opinion)

    just cause there is 0ppm on nitrates also dose not mean there is no other heavy metals and other nondesirable things in this water ie copper zinc etc

    I take it the pond has some algea growth (as all outdoor ponds have), thus the reason for the 0 nitrate test as all nutrients are being consumed.Like a scrubber effect,

    The rest of the bad stuff from tap water is still there. Rather stick to RO

    !00% Agree with Frans here you will also se 0 tds or phosphates as the algea will be storing this within

    you should test the tds of the pond water, then you will see why it isnt a good idea.

    This is a definate no no as Ro is not only about nitrate and Phos but about all the dissolved solids in the water.
