So about the flourite, I've never actually used it myself. I've just read bad some things that made me wanna stay away. Some said it does get soft and break down. Also, apparently the preperation for flourite, before you can put it in your tank is a horrid. Eco complete you just cut open the bag and dump right in, no prepping needed. Flourite you gotta wash and scru, etc.... theres a process to it. Many people stated in reviews things like " I never wanna deal with that again".
but yea, reading that stuff made me go with eco complete and its worked out well, looks nice, no mess, plants are thriving.
