My sand bed is 1" thick. By maintenance I mean taking my shirt off to reach to the bottom of the aquarium to remove fish waste twice a week.
If I get the Geophagus, those will basically be my only sand sifters. Right now all of the waste sits on top in large piles.Maintenance-- compared to? What kind of sand and how deep? Years ago I converted all my tanks from gravel to sand, primarily because my first sand bottom tank taught me there's far less maintenance than gravel. At least ime, in a moderately stocked, well filtered and maintained tank, with 1-2 inches average depth of sand, and with some fish that do sand sifting-- like cyphotilapia or geos-- I'm rarely having to do any sand cleaning, once every few months, some tanks more like once in six months.
All the websites I've been on say 5"-6". Knowing that I will go with about 6.
+1... again. With mine, average for full grown males has been between 6 and 7 inches and what I found was, like a lot of cichlids, you'll get at least a few in each spawn that grow fast, big, and beautiful and they end up larger than average, between 7 and 8 inches.That's usually the size they max out at, but they can get to 8". Speaking from personally experience
With a group of Geos you ain't never have to vacuum fish waste again. But do change water often.
Theoretically, that would mean less sand cleaning, just change out more water (assuming your water source is low in nitrates).I bought septobac about an hour ago and it is supposed to eat the fish waste, but in return it leaves more nitrates.
