Oversized skimmer?

[djryan2000]

I have a 20 gallon tank and am looking at skimmers rated up to 65 gallons. Is this too big for my tank? I have 3 fish and am considering a fourth - although I'm not sure if it's a good idea.


I'm considering skimmers like this one - AquaMaxx HOB-1.5 Hang-On-Back Protein Skimmer https://www.amazon.com/dp/B078NJXBGJ/ref=cm_sw_r_cp_api_i_5uvfEbSKZ1N07

I've always used higher rated skimmers, has never seemed to be a problem. Is your tank not drilled?

Number of fish depends on the fish, but 20g is really small.

+1 You can always run your skimmer on a timer if it's working too well.

IF your skimmer seems to work intermittently it is too big.
