CHILLER HELP!!

[Binditheaxolotl]

Sorry I’ve been posting so much! A lot of knowledgeable people are on here, and no one in my family knows anything about aquariums, except my dad who knows a tiny bit from his college roommate who had piranhas would a 108W or a 120W chiller be better for a 20 gallon tank?

Bumping this thread to bring it up! Hoping someone can answer this question.
