Likewise have heard that about Aquasoil, but I believe Eco-complete is all ready stable
Eco-complete doesn't alter Ph and has all the minerals in it to grow plants. That's about all I can remember. Haven't heard anything about ammonia. Although on the website it does say "will cycle your aquarium faster."
"Eco-Complete contains live heterotrophic bacteria to rapidly convert fish waste into natural food for your aquatic plants. It establishes a natural biological balance, which makes cycling a new aquarium faster and safer. Eco-Complete is packed in Liquid Amazon buffered black water solution for immediate organic water conditioning. Unsurpassed macro-porosity for healthy roots and bacterial efficiency."

, I would go with the Eco-complete if you like the colors. It's great for plants, looks natural. Just as long as the polys aren't too small. If I recall, the pieces might be larger flaky things(that's the technical term).
Although, not even gonna lie....I would kill for your red substrate or Sam's purple.......
