    Hi Guys

    How often do you need to do partial water changes and how many liters do you need to change. I have a 300L tank.

    If you can point me to any articles I would appreciate it.

    What other option are there to top up my tank if I do not have a RO unit?

    I suggest at least a 10% weekly water change.

    RO is the best option, if you start topping up with tapwater you going introduce Chlorine into your system that will promote algae.

    Would that mean removing 30L and replacing it with new salt water? Sorry sounds like a stupid question but I am already adding about 1.5L per day of top up water and do not plan to stock my tank heavily at all.

    That is correct, remove 30L and replace with 30L new seawater.

    Daily Evaporation is quite normal, especially in a hot climate like the middle east.

    Top up must be RO water only, no salt

    Hi GKirk, remember that the water lost to evaporation is pure so all the other minerals will stay behind and your salinity will thus increase as the salt does not evaporate. It will be very benefical to add supplements eg kalkwasser in the RO water to help maintain your calcium and alkalinity levels in the tank.

    A 30l weekly fresh salt water change will help dilute and remove the pollutants in the tank water and you will add important minerals to your tank as NSW and synthetic salt contain many essential minerals:)You will notice a definate change in polyp extension in your coral and the overall health of the tank will look a lot better.

    Please also remember that skimming also removes salt water so that has to be accounted for ideally on a weekly to monthly bases depending on how wet you are actually skimming;)

    Good luck with the journey:thumbup:
