Hello all! I am planning on setting up a 3 gallon Elassoma evergladei tank and wanted some insight on filtration. I was thinking of using an internal filter at 150 gallons per hour to provide adequate circulation to the tank. Question is...would this cause any problems for the elassoma? Thanks :)

I would suggest a small sponge filter. I see no reason to do much more in a 3 gallon tank with pygmy sunfish. I want to assume it is a 30 gallon tank, and you made a typo? Otherwise, you would be turning it over 50 times per hour, It is going to be more like the New River than a swampy backwater.

150 gal/hr = 2.5 gal/minute.  That's way too much flow for Elassoma in a 3-gal tank.  I would use an air-powered sponge filter with just a trickle of bubbles from a small air pump.
