Hi all,

I am running a 2ft planted tank. Livestock are Tetras and oto. Using eheim 2215. Thinking of adding media to it. What should I get?

1. I researched and should be buying eheim substrate. Should I get substrate or substrate pro?

2. Should I buy mech or mech pro

3. If I decided not to use substrate pro, can I use bio home plus?

4. Is the small box enough? The 5L looks too big.
