Is this a good skimmer for a 20 gallon?

I’d say yes but make sure it fits the chamber. Measure it from the inside and check the dimensions of the skimmer to see if it first before purchase. Or buy from Amazon, if it doesn’t fit just return it.

Ok I’ll do that!

Looks OK if it fits like above said.
No real need for a skimmer in that size tank though, imo.
My old 18" 20g nano cube and my 15" current 10g nano cube.
Carbon, 2 part, trace, and wc.
I put one in the 20 and did not see any advantage so I took it offline.

Ok but I’m planning on getting a 32 gallon also
