Love my tanks!
ok so I am trying to figure out if my tank would be alright with one overflow or whether I should go for two. If it happens that one is ok then do I change the size or not? Just as a reminder 150 gallon 48 x 24 x 30...
ok so now I am working on the placement of the drilled holes. I have a 40 gallon sump, I figure about 25-30 gallons in the sump during operation (if I am misconceived on this plz inform me). In a 150 gallon tank that is 30 inches 25 gallons evacuated would equal 5". I am assuming that this would be the level that my overflow box would no longer allow water to drain. If that is correct I also assume that the drilled hole would be slightly lower than the tooth threshold of the overflow? If so how much lower in the box would the hole be? or if I am retardedly wrong let me know
