starting a new tank

maybe not so good when you see this :silly:
have just added the first layer.. it is sand..

there's dirt everywhere, I should have washed them at the first place..
I think I have to do 100% WC everyday until it is not so dirty and I will continue to add the second layer of soil..

Should I keep my filter running?
Basically I use powerhead combine with sponge
