    Hi there. I am completely new at this and fear that I have already made my first mistake... I take delivery of my new 1.5m tank on Thursday. I was told to source RO water. I wasn't sure where to go, so I contacted a supplier of purified water. I enquired as to whether it was RO water that they supply and they confirmed that it was. I have ordered 600l. I did some more research and found that the Tds count is 30. Is this too high? Must I try cancel my order? I have ordered an RO machine, but the order of water was for the cycling process to start a bit sooner, rather than waiting for my own water to be produced. Can anyone help?

    At 30 tds you could prob get away with using a DI resin. But rather test for NO3, nitrates , and PO4 , phosphates and if those are 0 should be fine
    That tds reading is prob due to calcium, magnesium, sodium etc, get a breakdown from supplier and post here

    The problem that i have seen is that if you buy RO from one if the major mineral water suppliers is that they put back minerals in the water that you dont want. rather buy RO from an LFS and not just any place that sells it. :)

    just a word of caution here make sure to walk in with your TDS reader as I, when I first started, was sold tap water...

    Thanks for the advice. The TDS is made up as follows: calcium <6, Magnesium <4, sodium <5, potassium <3, sulphate<7, chloride<3, CaCo3 <5, nitrate<1, fluoride<0.2, iron<0.1, aluminum <0.1. Are these readings too high?

    This might be a stupid question, but doesn't cycling the tank (4-6 week), bring all these levels down anyway?

    only if something consumes it.

    Just a question, How much are they asking you for 600L of water?
    can you not use that as payment (partial) towards your own RO unit.

    A standard RO unit can make up to 180L per day, depending on your water pressure. Your tank could be full by Saturday if you buy your own RO unit today.
