If you build a fish room in your sunroom you should probably put some shade
cloth on the sunroom's glass to allow you to control the light over the
area where you put your tanks. Lots of natural light getting into aquariums
tends to cause problems.

There is *always* a bigger tank. It's the whole 'grass is greener' thing
:-) I personally would go for a 180 gallon if the extra cost isn't a big
concern for you. A 125g here is about $220, and a 180g is about $430 from
the same place -- almost 2x as much money for only about 50% more tank
volume. The extra 6" front-to-back makes a *huge* visual difference, IMHO,
and a 180g is the biggest "standard" glass tank.
For multiple tanks you could use a central filtration system and only need
to dose and CO2 inject one place to handle all the tanks. I just keep
adding tanks -- haven't thrown one out yet. I have 7 active tanks at the
moment and will be adding several more this year I think, including one big

With 4" of gravel a 125g will be 18" of water for your arms to wade in.
About 22" for a 180g. I think it was Tom Barr who suggested a 4" gravel
layer to me some years back and I do think it's a good idea. You might even
want to make some hills and maybe have some 5-6" deep areas. In a deep tank
this becomes a possibility, although it eats up a lot of gravel to do it.
And of course you're planning on using flourite, right? :-)

You can also build custom acrylic tanks if you have the skill and patience
to do it properly. All you need tool-wise is a circular saw and something
you can use for polishing (pad sander with buffing pad works OK). A scroll
saw and drill help too. If you aren't *sure* you can do it right though
you'll be better off just buying a prebuilt tank or having one built to
your specifications. A lot of plastics suppliers can put you in touch with
a shop that can do the construction for you. I'm not a big fan of the
appearance of plywood tanks myself and would stay away from them except for
large breeding or growout setups where appearance isn't a big concern. For
a large setup of DIY plywood/board tanks try http://www.tropicorium.com.
They have a bunch of 4x8 foot tanks they built that are about 2' deep in
most cases. They look somewhat odd up close but they seem to work OK for
them and they are BIG.
>How many of you have had both glass and acrylic large tanks and prefer the
>acrylic tanks? Why?
Glass is harder to scratch and I'd prefer it for that reason if given the
choice. Other factors start making acrylic look good though, like the
greatly reduced weight, the ease of custom fabrication, and the ability to
easily drill holes for overflows and the like. If I were to built a very
large tank of a non-standard (as in not available from All-Glass) size I
would absolutely make it out of acrylic. If I wanted any tank up to 125g I
would absolutely buy a glass tank. For a 180g I would probably go with
glass, but I could probably build it cheaper out of acrylic so I'd have a
tough decision for that particular size. I think if you want to go with any
size over 180g you'll want to use acrylic. A 180g tank weighs somewhere
around 500 pounds for just the tank so moving it will be incredibly
difficult when you set it up. Acrylic is manageable up to larger sizes.
Remember that once you fill the tank with water though any tank will weigh
literally tons, so the weight of the tank itself becomes negligible.
>Has anyone on the list successfully built a plywood tank?
Try that link again. They are a marine (salt water) wholesaler that does
retail on the weekends and I've been there a few times. It is a really neat
place to visit if you ever do any marine tank stuff and happen to be in
southeast Michigan. They are the only place I know of that has used large
wood tanks over any period of time in any significant number.
>Am I out of line wanting a lower, wider, longer tank? Any comments on what
>would be your perfect tank?
Nope, bigger=better. The only problem you run into is the cost of setting
up the tank (filters, lights, etc.), the cost of stocking the tank, and the
BIG COST of RUNNING The tank (electrical mostly). For some time I was
thinking about building a reef tank setup 4 feet on a side and 2 feet deep
(a square tank). It's really neat to have a tank that has no front or back,
but just 4 different views to look in to. A tank that size is about 240
gallons. I had also thought about a 4 x 8 foot tank, also 2 feet deep, but
that would cost a lot more to build. Turns out both were cheap since I
didn't build either ;-)
I like the 22-24 inch depth tanks, and the deeper tanks like the 180g with
a 2 foot front-to-back dimension. When you get up to 6 feet long the tank
starts to give the illusion of not having ends when you are up close
looking in which is a nice effect. If I were to set up a custom tank now
I'd probably make it 6-8 feet long, 4 feet deep (front-to-back), and 2 feet
high, which would be about my ideal size and around 360-450 gallons or so.
Maintenance would probably be fairly time consuming, and I'd have to run an
LFS of my own to dispose of all the plant cuttings.
