    Hi Guys/Girls

    Please could you advise me of the important water tests I should be doing.
    Currently I check Nitrate, Nitrite, pH and Phosphate. I also keep an eye on temperature and salinity.

    There's so many other water tests that can be done, shuch as Ammonia, calcium, copper, iodine, kH/Alkalinity, magnesium, dissolved oxygen, silicate or strontium.

    My tank is 6weeks old just and I've just done my first water change.

    Are there other important things I should be checking?

    Thanks :)

    I would definately get an ammonia test kit.

    What do you plan to keep?

    All I ever tested was

    Ammonia
    Nitrites
    Nitrates
    Phosphate
    pH
    kH
    Calcium

    Guys with advanced systems with difficult to keep SPS, etc will test more parameters. A 10% weekly waterchange not only dilute nutrients but also add trace elements back into the water, like iodine which is used up very quickly in the system. Crabs, shrimps, etc needs iodine to molt, your skimmer also removes iodine.

    Someone said to me I shouldn't do to many water changes while my tank is maturing? could I start with 10% weekly changes now after 6weeks?
    Also, regarding the water change, is it better to change with NSW or mixed SW?
    Does the mix have the trace elements needed?

    Alkalinity is very important to test....get it wrong and it will be very tuff to get a stable ph value.I would also go for a ammonia test kit.

    If you have afull reef system.....then add all of the above.With calcium,magnesium and iodine being on top of your list.

    Yes.Your choice really on the salt mix.

    Sea water advantage - free, might have some plankton in that corals will enjoy
    disadvantage - might have parasites and/or be polluted from drains, etc near the beach.

    Synthetic salt advantage - clean and most decent brands will have the needed trace elements

    Disadvantage - expensive, needs to be matured for 24 hrs
