good subrtate, thinking about using play-sand for the bottom of my nerw 90g, want to put live plants should i use some type fertilized soil first then put play-sand or can i use just play-sand? will have driftwood and live plants(about 4-8) like swords and anubis or java ferns so any help will do thanks guys/gals !!!!!!
If you want just java ferns and anubias just secure it to your driftwood with string. You dont have to worry is the substrate is sand or gravel
