hi there. i bought a fish tank yestarday (220 Ltr) and put a 25kg bag off sand init with out washing it

as the pet shop didint tell me to wash it. its been in the water for 18hr or so dose anyone no how long it will take b4 the waters clear ? i have keeped the filtter on should i be leaveing it on or off ?

. P.s sorry for the spelling
have a look at your filter, regularly. clean the impeller, but nothing else! no need to remove the sand. only causes stree to the fish, and more debris will be put in the water.
my sand was washed and washed, after 10 months i removed some. it took the tank 12 hours to clear (and that was washed sand!). dont worry, just keep an eye on your filter and all, should, be well.
i havint any fish yet

i was told to wait about 5days afther setting my tank up b4 getting fish ? i just want a good tank lol is it much to ask for
dont do a fish in cycle you need to cycle the
tank first which could take up to two months
if you put your fish in without cycling it
you will be wasting your money as the will most
likely all die so you need to a fish less cycle read this link
