Turface is good stuff. Cheap as heck and a little goes a long way. I tried it for the first time in a 75 gallon tank and am very happy with the result. I have eco in almost all my other tanks. I have pulled plants up to to inspect the root systems and was pleased to find lots of nice healthy roots. I am growing four leaf clover in the foreground and it is also taking root nicely. Glosso worked well also. Also something that might be a factor is the weight. Turface weighs next to nothing. Adds very little weight to your finished tank. That may or may not be a concern for you, just thought I'd mention it.
