Water Level - How High Is Too High

[Harry Muscle]

I'm doing calculations for where my water level will end up based on my flow rate through the overflow and I'm looking for feedback.

Based on my calculations my water level will end up 3/4" below the inner lip of the black trim of my 112G tank. Is this too high for safety? The black trim is about 1.25" tall so the water level will be 1/2" above the bottom of the black trim.

Unfortunately the hole us already drilled and the builder drilled it higher than I would have liked. So if this is generally too high I'd have to get Glass Holes to custom make an overflow for me with deeper teeth to lower the level.

Thanks,
Harry

I keep my 90g filled to about 1/4 inch of that inner lip , so I would say your OK

Mine doesn't have a drilled over flow but I keep it just above the bottom of the rim 1/3 of the way up.

I've only got mine about 1/2" below the black trim, which is about 3" below the top of the tank
