i prefer to keep my water level very high, with only 1-2" between the water level and glass tops just because of my bichirs that need access to air... otherwise i would only keep 1" in between
I think a full tank looks better, but I only run my 180g at 1/2 -> 3/4 , partially because of jumping, mainly because of floor weight (im in an apartment)
hey yuppa, i always wondered about that. how much can apartment floors take in weight?
do you live on a wood floored with joists or a concrete floor slab?
theres some fancy math that explains weight distribution over the surface area of floor and what beam spacing can take what..
however most buildings adhere to minimum building standards and i have never lived in a place that had closer then the minimum 18"
