Quick answer
The best substrate depends on your plants and livestock. Aquasoil feeds roots and buffers water, inert sand or gravel is simpler, and dirted tanks need careful capping.

Common Questions
Can aquarium plants grow in gravel?
Yes, many plants can grow in gravel if you add root tabs for heavy root feeders and dose the water column when needed.
Is aquasoil worth it for beginners?
Aquasoil helps rooted plants and carpeting plants, but it can affect water chemistry and may release ammonia early.
How deep should planted tank substrate be?
Most planted tanks do well with about 2 to 3 inches, sloped deeper in the back for root space and visual depth.
