Gravel Below Aquasoil?
About to attempt dry start method in a 15"/38.1 cm cube. Am wondering if i should put a layer of gravel underneath my aquarium soil (Netlea Langa) to provide room for roots to develop, and extra media for microbial life. I've seen quite a few advanced aquascapers on Youtube who add sand or gravel underneath, and am wondering if it will be beneficial for me in the long run, and if it matters which gravel I use. I have a bag of CaribSea Super Naturals Peace River gravel (2-3 mm). Would that do the trick?
