Newbie Question: Gravel Depth and Aeration

A few questions for you guys today.

I'm setting up a 33 Gal 36" x 12.6" x 18" (Hagen All-Glass A-3023) tank
soon, and I'm getting all the bits and pieces I need, but I can't seem
to find an answer to either of these questions through Google.

How deep should me gravel be? This is a freshwater tank, and I know it
should probably be a darker colour, but an exact depth is never really
specified anywhere I look. Is 2 inches (average, I know it should be
varied) too much? Also, is there a magic formula I can use so that I
don't end up buying too much extra gravel? Would one 25 pound bag do
the job?

Second question has to do with aeration. In the tank I had when I was
little, I had an air stone to help with aeration, but no filter for a
long time, so I think we just kept the air stone, because we didn't know
that a hang-on-back filter could aerate as well. My question is, is the
filter going to do the trick for aeration, or should I get an air pump
as well? The filter I'm using is an Aquaclear 200.

Thanks for any info you can provide!

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.

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.

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!

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!

You might want to reconsider. Real plants do quite a good job of eating
up the ammonia-nitrite-nitrate byproducts of the fish and not only keep
the tank healthier, they may prevent or at least lessen algae.

And as another beginner, I found that they're not hard to grow. In
fact, I recently pulled up a big double handful of pygmy chain sword
plants because they had completely covered the bottom.

As a person incapable of even jarring a betta without some java moss, I
have to ask you to reconsider running a plantless tank. Plants
dramatically increase the water quality and there are plenty that will
grow under lower lighting conditions. I'd suggest setting up your tank
with 2" of fine natural gravel. It's not much harder to vacuum and that
way if you want to put a plant here and there, you can add a fertilizer
tablet at the roots and you will have enough gravel for the plant to grow.

An aquaclear 200 is the right size, but George makes a good point about
bio wheels. If you don't have many plants, a filter with a wet/dry
section like a bio wheel breaks down dissolved organics and keeps the
water quality much higher.

Hmm... now I've got to consider this. When you're using plants, do you
usually put a layer of substrate below some pebbly gravel? Do you
happen to have any good websites for plant information? I'm thinking of
getting started with some tetras, so I'd have to aim for a plant that
likes that same kind of pH, right?

Any gravel or sand 2-3 mm or smaller that allows plants to root in it is
fine for a basic planted tank. Plants can't root and spread in pebbly
gravel. If you use plain gravel, you need to put laterite (an iron rich
clay) tablets at the roots of crypts and swordplants. There are some
new high-tech substrates, Fluorish, Eco Complete, and Onyx, which are
porous clay with minerals plants need at a particle size designed for
plant roots. If you use one, you don't have to fertilize the substrate.

As for pH, you will have the best success if you keep your tank at your
local tapwater pH. Fish HATE pH changes and if you use chemicals to
adjust your pH, then the pH can change at every water change! Most
community fish and plants do fine at pH 6.5 to pH 8. This includes just
about every species of tetra. As in gardening, choosing plants for your
level of lighting is the most important consideration, followed by
appropriate size.

I actually wouldn't recommend you start with a high light tank because
they're fiddly. Algae can grow awfully fast when things get out of
balance. 1-1.5 watts/gallon will let you grow java moss, java fern,
Anubias spp. and many species of cryptocorynes, without too much algae.
Plan your eventual fish load for a few otocinclus, a bristle nose
pleco, and a siamese algae eater and your plants and tank will be mostly
very neatly cleaned of algae.

I used Eco-Complete mixed with sand and was very satisfied with it. It
is a little pricy, but sure makes the plants happy.

BTW, as we've discussed here before, if you take traction sand and sieve
out the really fine stuff, you've got the right size of coarse sand or
fine gravel you need for plants. It may be too late to get any this
spring unless you live in the far north, but it's hard to beat the
price. IIRC, I paid $5 for a 60 pound bag.
