bro, unable to give you the exact price of the tank and equipments. Here's a rough guide of the price u sld be looking at. .
1) tank/sump/cabinet - $400
2) Eheim 1260 2nd hand ($80-$100) however, i wld advise u to get eheim 1262 instead.
3) skimmer, try to go for the best. i recommend beckett. ($500)
4) sand, 10kg for $6, u need approx 80-100kg.
5) Live rocks, about 80-90kg now. Get from pple who decommission, will save u lots plus the rocks are cured. However, might not get the shape u wan. ($3-$6/kg)
In short, set aside $4000 for a 3ft tank.
