    Detailed help request
    Are you experiencing any problems in your tank?
    Yes
    Brief Description
    set up my tank 3 days ago with ro water and salt mix. woke up this morning and my entire tank is covered in a white film. looks like a calcium build up but it is everywhere, especially on my heater which is completely caked! Even my arogonite substrate has clumped together. this is a serious issue!
    Tank size
    900 x 550 x550
    System Volume
    300L
    How long has your tank been running?
    3 days
    What livestock do you have?
    nothing
    Water Parameters
    Calc 440ppm
    What lighting is over the tank?
    -
    Pumps and equipment
    -
    Maintenance
    -
    Other info and photo's.
    Because i live on a game reserve i use borehole water which does hold quite a bit of calcium. i would have thought that the RO unit would have helped to have got rid of this, but now some serious reaction has taken place. i have used this water in my freshwater tanks with no issue at all. Is there any solution??!!!!:eek:

    hi,
    this is some form of precipitation, what is the water temp? sounds like the salt has not disolved completely, also what is your salinity now?

    this happens to me every time i fill a tank with fresh salt water.

    Its not really anything to be worried about. You will see if you run your hand along it, it comes right off. As to what exactly it is i have no idea

    its probably calcium carbonate thats precipitated out of solution, seen it before, since everything is new, its might just be the affinity of things to attach to all things new etc.

    i would stir things up and get it back in solution and use some filter floss and see if it comes back. also check your ph and alk and magnesium as these are all related

    How did you mix the salt? The right way is to first put RO in tank, heat up to +- 26deg and then add salt slowly. Add/mix to manufacturer recommendation and give chance to dissolve for 24hrs. Test salinity and adjust if needed. Then add substrate and live rock.

    and

    Did you measure the pH? I quoted this for you

    "Excessively high pH, however, can also be a significant problem in some aquaria. In addition to potentially impacting the aquarium inhabitants' health, high pH can lead to other problems, including the precipitation of calcium carbonate on objects such as heaters and pump impellers. Such precipitation can also artificially cap the attainable levels of calcium and alkalinity. For these reasons, pH is a parameter that aquarists should monitor."

    Yep check the PH and report back. When i mix in PH buffer it happens in the container i used so not a train smash, you can lower the PH if its too high with lemon juice

    Thanks guys, im using Red Sea (coral pro i think)
    put RO water into tank and then heated up then added salt. only added my substrate once all salt had mixed in.
    will go check PH etc now and find out what my params are

    is the water clear or cloudy?
    How quickly did the salt dissolve when you first added it?
