I really need to save some money so I was planning on using a base layer of Schult's Profile Aquatic Soil, and than placing a final top layer of eco-complete on that.
First, has this profile stuff been on overall good subtrate for aquariums? Does it mess with water parameters? What color is it, at home depot it was kinda grey and I'm not sure if thats the same profile everyone talks about here.
Secondly, how un/effective is layerint, I'm not mixing because I want black only to show on top. Will their be problems with plant growth since the roots are in different substrates, and will the eco-complete be uneffective as the roots bury deeper into the profile?
