    Hi Guys,

    Got a question about non-cycled RO water mixed with synth salt mix.

    Heres the deal, I have a fully cycled system up and running, DSB, Mature LR and mature substrate.

    I would like to transfer all these into my new tank, BUT BUT BUT i want to fill this new tank up with fresh RO and salt mix.

    So everything will be mature just besides the water.

    My question is, will I need to cycle again for another 4 weeks ???

    in theory nope, but i would add microbelift to remove the ammonia and stop the new cycle etc. i moved my tank and did the same and never lost a thing. i did use 50L of old water, from 140L to 300L tank

    If you remove the sand and transfer it to the new tank there WILL be a cycle. I rinsed my sand before adding it to the new tank when i also moved everything across. You will need to keep an eye on ammonia if you dont wash the sand

    Personally I'd use 50% of the old water and 50% new water, then over the next few days do a series of smaller water changes water changes. If you're using the same substrate you'll probably have some murky water so I'd set your skimmer to skim wet this will strip some of the residual detritus and lighter particles from the water. Then top up with new salt mix until you're comfortable you've diluted all the old water. BUT monitor your salinity carefully. Adding a bacteria source will help to limit fluctuating NO2/3, PO4. Good Luck:thumbup:
