Hi, everyone.
I've been lurking the forum for awhile now and finally decided to make my first post main reason is because often time my questions have already been asked and answered (hooray the search engine). Though, I recently ran into a situation and could not find an existing thread similar.
Recently, I bought a used 75 gallon tank with corner overflow that comes with 3 drilled holes. Was wondering if I could use 2 holes to drain and 1 return? Or should I just plug one of the hole off? And what is the main purpose of having 3 drilled holes in an overflow instead of 2? Thanks in advance for your help!
Oh yeah, Im currently running freshwater with a 55gallon wet/dry sump.
