Geez, I only paid $300 for my used 125g and I probably could’ve found one for cheaper.Tanks are extremely expensive where I live lol. I live in a pretty underdeveloped part of the U.S. so everything automatically comes with a higher price tag. I spent about $350 to fix this one. The only LFS around that sells tanks is a considerable drive and they want $1,200 for a bare 100 gallon. I pretty much have to order all of my reefing supplies on the internet and have it delivered to me. As far as the rim goes…I know a guy. He only charged me for material and he has done multiple rims for aquariums larger than this. I checked it this morning before heading out for work and it’s still holding so fingers crossed. I’m pretty confident it will hold up for years but I’m still letting it sit for a while. Thanks for the pun though lol
