Yo guy, I have just cleaned the canister and tank. I also added a skimmer, bioball and removed carbon. Hopefully the condition will be better. Will do NO3 + PH + KH test in 2 days time. Will update you.
Now my tank look suck.
Will post the after installed pic
I decided to go for sump but I need your expertise to show me the configuration of sump and overflow box. Thanks.
