There is no one right answer to how much. If you are not going to grow plants then
you have many options for gravel and I think 25lb will give you adequate coverage,
maybe more like 1". The bags sometimes have coverage information.

If you intend to grow plants then you need to do some research on exactly what you
want to use for substrate, but it probably won't be the large, epoxy coated
pebbles. Possibly sand, flourite, or other non-conventional materials. You would
also be aiming for that 2" depth or a bit more.


I was planning on sticking with artificial plants this time around,
since I'm re-learning how to take care of an aquarium since it was so
long ago. So, that's good news, thanks for the info!


All these power filters provide enough surface agitation that a bubbler is not
needed. But the AquaClear 200, is that rated for only 20 gallons ? If so you you
had better keep stocking to a minimum. Alternatively, you could consider one of
the models with a wet-dry section. Marineland makes ones with a biowheel that are
a good bet.

You had me concerned there, for a sec, but I just double-checked on
Google and this site, as well as a bunch of others, says that it's max
capacity is 50 Gal http://www.aquariumproducts.com.au/prod128.htm I
think I'm interpreting that right, maybe you could explain, if I'm
wrong. Again, thanks for the help!
