Filter carbon insert

[melissa1977]

I currently have two tanks.

I have a 20 G high heavily planted with 3 dwarf puffers and 2 ottos.
And I have a brand new 10 G with nothing in it yet ...

I ve fishless cycled my 20g high without carbon insert but with the sponge and bioballs. My tank is fully cycle and is now happily habited. Everything is going fine after one month (no ammonia, no nitrites and low nitrate.)

In my new 10g i am currently doing a fishless cycle and i am not using the carbon insert but bioballs and the sponge ( I am using bioballs coming from my established tank).

Am I doing it right ?? Should I be using the carbon insert ?? 8O

You are doing just fine. Carbon is not necessary as you've already found out cycling your 20 gallon tank. Trust your own experience.
