    Hi
    I am confuse now. I have to start off from scratch. On the forum everyone tell me i must mix my water in the tank with the pump and heater on. But at the LFS they say: never mix water in your tank. I will expierence problems. So which way is correct?

    I think you getting some wires crossed here.

    It sounds like you are describing when you mix RO water and salt together. It can be advisable to use a pump and heater to help the salt dissolve and get the water up to the tank temperature.

    You don't mix salt and water in the tank ;), do it in a separate bucket.

    But you do create flow in your tank by using powerheads and you want to have a heater to keep the water at a nice comfortable 26°C

    dont know who told you to mix salt water in your tank. its wrong! you mix it first, make sure and everything is dissolved then throw it in.

    i put i small pump into my water drums and let them mix over night before using it. proffered way IMO.

    Marjolein, I take it you are setting up your system for the first time and want to add the first batch of water and salt mix. You can mix the first batch in the display tank without problems provided the following are adhered to.

    1) The water used is RO water.
    2) Live rock and live gravel is not used.

    Once you have filled the tank with RO water you can then switch on the circulation pumps etc. Then you can slowly add the salt mix bit by bit until a salinity of about 1,024 is obtained. You must then let the water circulate for at least 24hours before you add live rock and live sand to your DSB.

    However all future mixes must be done in a container and circulated/aerated for 24 hours before use.

    Guys, I don't think you've been following Marjolein's threads...

    She is starting her tank for the first time.

    Marjolein, both bits of advice is correct, in context...

    You can safely mix the salt and RO water in the empty tank the first time you start - in fact, it is the preferred method.

    After the tank is full, and you have living things in the tank, you should never mix salt in the tank again, as the salt will be very harmful to the inhabitants. you should then use a bucket, drum, etc. to do the mixing, and then allow at least 24 hours for the salt to fully dissolve and for all chemical reactions to complete, before you add the salt water to the tank.

    just remember that when replacing evaporation, it must be with clean RO and not salt mix as the salt does not evaporate only the water ;)
