I'll have a 75 gallon for you if you got the space... Had it running for 4 years and I can donate it to you if your willing to pick it up after I set up the new tank in 3 weeks... I'm just doing a swap.. It's missing the center brace but has held up for 3 years like that and I'm pretty sure 3/4 water filled won't do it harm... Anyways hit me up if interested.. I'm setting my new tank up nov 15,16,17 so it'll be available after that
