I have a 45g hex that's almost 10 years old with UGF (one
power head) and active plant growth. Lately, it's mostly
java fern and moss and a few crypts or other broad leaves
because of lower light.
Father forgive me, it's been six years since my last water
change. The rosy barbs are still breeding in there, though.
My 180g is ?6-7 years old, with an inactive UGF (inactive
for 6 years now). Everything grows or breeds in there.
I have open access to the glass bottom of the tank...
there's very little mulm or detritus there. I can take
pictures if you want (it's a 3/4" space, nylon screen over
egg-crate), followed by 2-3mm gravel and vermiculite).
Most of my tanks have nothing but substrate. A couple
have external filtration. I suppose my preference is no UGF,
except I like the idea of dosing under the substrate so low
flow RUGF is still interesting to me.
