Just spent almost 5 hours the other day re-scaping my 33gal.
Here's the result:
Specs:
Tank: 33 gallon long
Filters: Aquaclear 300, under gravel filter with powerhead.
Hagen C02 machine, DIY media
Lighting: 80 watts fluorescent (two 30's and one 20)
Substrate: gravel
Getting things back to normal. Our tap water is still not up to par so I've been mixing filtered water in the water changes.
