Going to lay down two tubs of this

It seems to be a decent substrate having looked around. On top of this I have 2 bags of gravel from pets at home

It’s got a decent mix of gravel sizes so should be good for the plants that I am planning on putting in. In total I will have 12Kg of the substrate and 40Kg of gravel, which I reckon should cover the bottom of the tank nicely. If it doesn’t I have just checked on the pets at home site and they have 5 bags of it in stock in Kirkcaldy – nice feature and you can get them to reserve it for you before you go – very handy. Think plants might be my next post…….
