Just got set back on the build, went to go measure and wet test the tank i was going to use as my sump and it had a hairline crack along the side so i had to toss it. Ive got two options, use the 55 gallon tank i have laying around or buy a new tank. Cant decide if i want to use the 55 although it provides some good options for space and in the long run if i ever upgrade.
