| | Earthworm Castings
I have an empty tank sitting in the garage and after digging so long in this forum I decided to setup another one.
This time I maybe going Iwagumi style. However, I can't afford a good 5-10 bags of Eco-complete and such. I am a college student. LOL
So I was doing some reading and came across some people mentioning about earthworm castings (EC). Has anyone tried it before?
Could it be possible I fill in about a good 1-1.5" of it and top the rest off with Eco complete, and maybe some 3M black quartz sand?
Any suggestions? Advice? tips?
