    Hi,
    what is the bare minimum with what i can start a cycle?
    I was thinkinh of getting the ball rolling with only the DSB, substrate in the DT and two pieces of LR in the DT, will this work?

    yes that would indeed start a cycle, but what size tank would you be putting it into and why would u want to cycle with bare minimum? if you add any significant amount of LR after youir cycles been through its main stages, you will just kick into another cycle. why not start off with a decent amount to get the biological aspects going?

    thx crispin, thats why i first ask the q here on masa.
    i dont have the money now to buy all the LR (have to buy RO unit, salt, heaters also) so i thought of starting the cycling so long with bare minimum and add some rock later, makes sense what you'r saying.

    tank is about 370l without rock and sump 100l.

    then why not just add 20kg of LR for now, and then add on more later, but dont add too fast once the cycle is over add slowly so that the system wont go into shock and start the cycle all over again

    You'll be fine, as long as you don't suddenly add 100kg's all at once, if you're on a budget then just add one or two pieces a month, this will probably be better in the long run as your LFS may get rock from different places so you'll probably end up adding different bacteria strains and different lifeforms from the rock which is a good thing.:)

    good advice there viper :)

    for that size tank you dont need massive of rock any way, so go slowly as your budget allows:)

    Just look out for unwanted hitchhikers.

    When you cycle your tank, it is easier to get them out, but if you add a rock or two per month later. You might make it difficult, depending on other livestock in the tank by that time. Suggest you keep new rock you buy later on in the sump for a few weeks. To make double sure no crabs or mantis shrimps are hiding.

    you are probably looking for around 40kg max. and around 20kg for an open lower reef, so you could easily add 5 kg's here and there as you go along.

    also getting your sand bed to mature is a fine way to get the tank going and thats just a few cups of established sand from someone elses tank, so wont cost you more than your petrol.

    just dont take advantage if someone does say you can take from his sand bed. I had to stop one fella after he had taken out about 3kg of aragonite. i put it back and gave him a cup which is all that he needed :)
