What's your level and why?

[minerwilly]

that's my thinking too, as long as there is enough open water at the top

i like to keep it just over the trim aswell, dont like seeing the water line.

 

[unstopable4700]

i ahree w/ greenterra. at the trim or a hair above

 

[richard4878]

I keep mine about 1.5 inches from the top, so that my gar can grab air from the surface easily without hitting his beak on the glass cover.

above the trim, if it gets lower than that it's time for a water change. I don't like looking at the water line either.

 

[albyoscar]

I keep all but my 180 full to above the trim, The 180 has about an inch and a half out because i have an aro in that tank and im a worry wart

 

[Merbeast]

I keep it above the trim. I hate looking at hard water deposits, and when the water line is below the rim, sooner or later there will be visible hard water deposits on the glass. YMMV.

My tank is 90 percent full. I leave 3 inches off the top because I am breeding mystery snails. So far I have full blacks, full yellows, half & half, turtle yellows with black spots, turtle greys with black spots, and full greys (not that I know how I got full greys, or turtle greys as I have been, until recently, been breeding yellows with blacks).

Each of my 15 tanks has different needs.
most are full past trim,no water line.
I have 2 or 3 that are lower.....
one cause I have a large clown knife and it gulps air.
(would smacks it's head on the hood)
the others are Red Devil Breeders and they fight & Splash water...
I was walking by my new pair of Devils and noticed the water was rocking back and fourth like waves in the Ocean.....LOL
That is why I keep their tanks down a few inches.(I fill for photos though)

I have seen some nice tanks that only had a few inches of water.
