Re-leveled a 180g tank without draining it

[125mph]

My new reef savvy tank, unfortunately was not level. The level left to right look good but the front to back was off by 1/4” over only 2 feet.

This thing is a beast and I avoided re-leveling it.

Today, i found a post about airshims and was able to level the tank myself and I only drained approximately 45 gallons of water. No rocks or sand were removed.

I used these air shims and worked like a charm.

Glad they worked. I've never seen them. That said at $18 each times four I would have drained more water and pounded wood shims under the stand. Its what I did to my 180.

These look brand new after being used 45 mins, so they will be returned today :)
