Hi all,
I am still in the process of building my 125g tank. I used a 4' level to shim the stand and I thought I got it perfect. However when I filled the tank with water, the water level on one side is 3/16" higher than the other side. Is this difference okay for a 6' tank? The stand is sitting perfectly flat on the floor with no gaps. I guess the concrete basement floor is off a bit. Apart from the fact that one overflow will get higher drain than the other, which I can fix by raising the overflow teeth level, will this difference cause the tank to leak?
Should I drain the water out and shim the other corner 3/16" higher?
Thanks all for your suggestions and helping me out several times.
