How high do you fill your tank?

[coach_z]

i have generally filled my tank to the bottom of the trim line and have had a bit of surface agitation due to that.

last night i needed to top off my tank because i couldn't sleep so i added 2 gallons of water which was just shy of overflowing my tank....and i had almost no surface agitation!!! yaya! which is good because it will help me keep my co2 in my tank.

anyone else fill their tank this high? any reason that i shouldn't do this again?

With a HOB- you kind of have to fill the tank up to the trim... I keep it as low as I can without the "waterfall" effect.

it really depends on what I have in the tank and what kind of filtration I use. i see no reason why you shouldn't fill it that high.

MsJ. since you mentioned it, i do have the nerite snails you sold me in this tank....i know they like to hang above the waterline......tank is tightly sealed with a glass top.

They will hang onto the underside of hte top as well, they don't NEED space above the waterline like bridgesii.

lol maybe they will eat my hard water spots on my glass lid!!

When I didnt have brigs I would fill it all the way up to the tippy top.

I fill mine up as far as I can before it overflows

Filled to the rim. Mine are AGA so they have the black lip at the top and I fill it to the bottom of that.

2 of my tanks all the way to the top but my other I leave about an inch in the top exposed so my SA Lungfish has room to breath!
