Firstly, some of the materials.
10 bags of 1-2mm Shirui gravel. 40kg total. This is still insufficient. Need another 6 bags I think.

They can't be too fine as I'm using a tube undergravel system.

River Rocks. They're not very hard, can be broken into smaller pieces.

I will be using a top filter box[5 liter]+powerhead and also an undergravel tube system + small powerhead for the filtration.


Using a rock to keep it the tubing from floating.
