    Hi,

    I've had my 90 litre tank for 2 years now which has been running with an external filter containing nitrate/phosphate reducing granules, filter sponge and a small amount of live rock.

    I've recently bought a Red Sea 170 and am planning to by a protein skimmer and just run that initially. Will I be ok to just put what I have in the external filter into the sump without causing any issues?

    I think the Red Sea 170 holds 130 litres in the main tank and I wont be adding anything new fish/coral wise until its all settled down so shouldn't affect the equilibrium too much.

    Thanks in advance - A happy new sump owner :aaaaa:

    That's pretty much what I did when I swapped from a filter to a sump and had no problems

    Or you could put new / different media in the sump and run them side by side for a while, then switch the external off
