You're talking about a wet/dry filter with a sump.

Sumps typically use an overflow siphon where water is siphoned from or near
the top of the aquarium; if the return pump fails the water level of your
aquarium only drops a couple of inches before the siphon is broken. Sumps
normally have a lot of reserve space so these extra gallons end up in the
sump and not on the floor.

If you are going this route you should consider having your tank drilled
through the bottom or the back (if the bottom is tempered) to accommodate
this kind of overflow system.

If you don't want to drill your tank you could also go with a special
skimmer box, like the Marineland Skimmer Box and Overflow System, but it
isn't quite as neat--restarting the siphon isn't as simple as restarting
the return pump with this kind of setup.

A simpler option may be to go with a good canister filter. These filters
are completely sealed environments--if the pumps stops, the water flow
halts immediately. Large high quality canisters like those made by Eheim
and Rena are quite versatile.

Honestly, I don't think you'll find much benefit in going the wet/dry sump
route unless you're in the 90+ gallon range or you plan on adding a lot of
extra equipment on to your sump besides a wet/dry filter.

Thanks for the advice thus far.

I am not prepared to drill a hole in my tank because I am not that
brave. If I decide to go that route, I will probably ask my retailer
to do it.

My only experience thus far is a 30 gallon fresh water tank since
Christmas. I am considering placing a larger tank in the family room
-- may a 90 to 110 gallon fresh tank.

The reason of quoting the wet/dry filter is that it has both aerobic
and anaerobic properties. I thought that it will also give the water a
better chance to exchange with the air. Yet I am thinking about using
a spraybar for the water return anyways. I like the notion of a
canister filter. Yet I heard that they are a bear to clean.

With the larger tank size, othe than requiring a filter or filters of
high capacity, are there other considerations?

Thanks again.

Tank drilling is not something you should ever attempt on your own unless
you have been properly read or trained.

Wet/dry filters don't do much for anaerobic bacteria. Water passes far too
quickly through the filter for there to be any anaerobic zones. Wet/dry
filters are nitrate factories, not nitrate removers. You would need to
connect some other nitrate reducing device to your sump, like a specialized
fluidized bed, if you wanted to remove nitrate this way.

A wet/dry filter will blast CO2 out of your system rapidly too, so if you
want intense plant growth you may have to compensate with good CO2
injection.

Good ones are simple to clean. Cheap ones (e.g. Fluval) are harder to
clean, messy to start, and often break. A good large canister won't
require a lot of frequent cleaning anyway.

You'll want significantly stronger lighting to compensate for the increased
depth, if you want to keep plants.

Something like a Phython might be a worth while investment if you want to
cut down on a lot more bucket carrying.

Weight is a concern. Water weights roughly 10 lbs. per gallon. You will
want to make sure your tank runs parallel to sufficient floor joists or is
properly supported by other means.

Other than that, larger tanks are a lot like small tanks but with more
water. That can sometimes translate into a larger room for error. ;)

err... that should read PERPENDICULAR TO, not parallel

Again, thanks for the advice.

I guess what I meant by:

"With the larger tank size, othe than requiring a filter or filters of
high capacity, are there other considerations?"

I was wondering, besides the higher filter capacity for larger tanks,
what other considerations should I give?

Thanks for any response in advance.

I meant in the FILTER DEPARTMENT. Sorry, my oversight.

Have to disagree......
got 2 x 6 foot marines in the living room including one @700L
Ain't no way they are going into the basement with algal cultures while I
have 2 new rays!!!
Big tanks need to be in your face or ya may as well just have a bloody pond
outside......

I agree, I put my tanks in most of the rooms of my house. I sure
wouldn't want to tuck them into a room where I couldn't see them.

The large, heavy tank question has been discussed at length in the
past. It is just reasonable to consider if your room construction can
support a ton over a small area of floor. My floors are concrete, no
serious problem. If your house is big enough to have these tanks,
chances are the construction is strong enough. However, considering
the costs involved isn't it wise to consider the stresses before
committing the money?

Just never had a prob before is all. setup a lot of tanks now and had a lot
of people look at floor and say where is good and where not.
but yea depends on your floor, maybe we just build well over here or
something but I gotta house of heavy tanks and ya I flooded a few things in
me time.
but floods are part of the fun, get a bath level alarm and go play xbox 360.
if i had a cellar it would be a playpen for me birds.
heh heh

Ok consider that aeration, biological filtration and mechanical filtration
are not the same thing.
All three become more seperatly important in a big tank.
As do large ornaments, little ones look shite.
taller plants, more powerful lights.
also a sturdy stand and thicker styrofoam.
You may need bigger powerboards to accomadate timers and more plugs.
Bigger tanks also cost more to heat, take longer to heat up and more need
more decholinator and medications or salt to treat.
Bigger tanks use more expensive equipment espec marine.
But they are stable, and can take more fish.
But little fish in big tanks is the secret to happy fish.

All Filters are good as long as the amount of bacteria growing on them
matches the amount of food being fed.
Maintain bacteria cultures by rinsing filter media with water from the fish
tank.
Big tanks with big stands have big areas to hide equipment, which I like.
4foot tanks can take advantage of commercial and cheap 4 foot light fittings
and tubes, while 4x2x2 and 6x2x2, infact any ?x2x2 can take advantage of2x4
timber for construction of quick easy stands.

not exactly sure what your question was but heck this killed some time I
spose...
:P
