Whatever i understood about this topic is from this forum only...due to some unavoidable circumstances like space,room shortage and time shortage and moreover shortage of experience and knowledge i can not go for a hi tech tank at this moment...believe me i never knew the term diy,hi tech low tech,co2 diffuser,macro micro,laterite,soilrite and scaping hob filter etc just even 20 days back before i start reading this forum...thanks people out here..
Now my plan is:
1.tank :18" length,15" h 12"b no hood as of now.
2.filter: a top filter(big question)
3.substrate: collected garden soil from local nursery
Sufala from a local nursery,construction sand collected,as well white sand gravel bought 5 kg @ rs.38 pkg
As didnt get soilrite and didnt try for chetla near desher khabar still now(in formation as per the forum i collected

Will go for a 3:1 garden soil and sufala and will make a 2" layer.top on that white sand and con sand 1.5"
4.rock and bogwood collected and processed as per diy(its like chto mukhey baro katha)
