Thanks all, after much study and reading and more reading I have decided mixing substate products is not the way to go. Going with eco-complete all 3 inches. All the fancy stuff will be tested in small tanks with no mixing. I have grown plants in aquarium gravel fo 30 years. I don't know what has gotten in to me. Just because I don't use ada the project will not "bomb" I hope.

Reason: adding something... not mixing
