Mixing or layering substrates.
I am new to this hobby but have spent the last 6+ months researching. I purchased a 120 gallon tank. I am stuck on choosing a substrate... there are so so many options and opinions. I am doing planted for sure. I was curious as to your thoughts of mixing substrates instead of layering So that way I would get the benefits of multiple substrates without it being so deep. Thoughts?
