I've been doing a bit of research and it seems that coconut fiber breaks down much more slowly than something such as peat moss. It takes about 2-3 years for fiber to break down. Some coconut fiber have salt in them, but the more dangerous ones are from gardening types. Reptile fiber companies have guaranteed that their products have very minimal salt content. Otherwise, from what I can see, the fiber is pretty much inert. It doesn't have much nutrients. So I was thinking about root tabs or something along those lines.
The newts don't have any problems climbing into the land area but only one is up there most of the time. The other three prefer to be underwater. My goal is to cover the entire tank, both the aquatic area, the slope, and the land area, in plants. I'm going to be changing the aquatic substrate as well as the land area substrate so the plants will grow more evenly than they can in gravel.
