Planning bringing a 55g online to grow plants and eventually add small schooling fish.
Plans are from top to bottom:
- 40lb bag of Safe T Sorb (approximately 1.75" evenly spread)
- .5-1" pool/playground sand from lowes
- light sprinkle of osmocote granules + kno3 dry ferts
- .5" organic peat moss
Are there any factors or concerns to be aware of with this combination?
