Fishtank from Lincoln NE
At the gas store. Didn't see any fish but cool idea.
Ahh, a classic. This actually WAS how gas was dispensed...
it was pumped up into the glass cylinder, then delivered via gravity to
A few folks have fish tanks made of these old glass gas tanks... and
there have been attempts at acrylics.
Thank you for sharing. BobF
Questions about second hand tank. FW Use
I recently purchased a second hand 20-gallon extra tall.
Even though I can't have as many fish due to surface area, I fell in
love with the appearance.
<As many do. Tall tanks are lovely for aquascaping, and if you have
sufficiently strong lighting, provide plenty of scope for a nice "jungly"
arrangement of plants.>
I have a few questions to make sure I can turn this into a healthy home
for my future fish. First and foremost, are there any recommendations
for making sure the tank is sanitary for use in case the previous
residents had a disease?
<You can sterilise with a bleach solution diluted until barely smelling
of bleach. Wipe down, then rinse thoroughly, and then rinse even more.
Fill with water, leave overnight to soak out any little bits hidden in
the crevices, then empty. Rinse again. Should be fine.>
I have read mixed reviews about undergravel filters. I will most likely
not use it, unless it will truly be a boon to the fish.
<Undergravels can work extremely well. But they are very limiting in
terms of aquascaping, so if you want terraced gravel, lots of plants,
and piles of rocks, skip undergravels.>
Also included was a 4 way gang valve, an Aquaclear 200 power filter
(sponge included). I don't see them sold in my area anymore, so I may
have to purchase carbon pouches online.
<Skip the carbon. Don't need it. Get as much biological media in there
as you can, stuffing any empty compartments with filter floss if you
There is a clam shell bubbler, which I suspect may provide bonus
aeration due to the depth. Even if not needed it looks cool.
<Mostly a toy, but yes, adds a little extra water movement.>
I am considering buying sand for substrate, which leads me to a few
questions about the advantages and disadvantages of it. I intend to have
a single species tank, leaning towards lemon tetras or neons. Since
there is less surface area and more depth, I am wondering if I should
follow the stocking rules of a 10 gallon tank. I would rather be
understocked than overstocked.
<If you stick with small tetras, the standard rules will be fine. For
this sort of tank, something like 6-8 Lemon Tetras, half a dozen
Corydoras, and a single specimen "personality" fish like a Dwarf Gourami
or Angelfish would work just fine.>
Is fish food in women's pantyhose a good cycling method?
<Can be. Or simply add flake daily as if there were fish there, and do
you usual 25% water change every weekend. You should find the ammonia
level goes up then down quite quickly. The warmer (up to about 28-30 C)
and more oxygenated, the faster. Within 3 weeks ammonia should be zero
and nitrite close enough to zero (sub-0.5 mg/l) that you could add the
first hardy fish, I'd recommend Corydoras aeneus or Corydoras paleatus
if either of these appeal, rather than Tetras, Gouramis or Angels.>
Just a few basic questions so I can get on the right foot. I'm really
excited (33 acting like 8) and want to have a successful home for my
Many thanks- Steve

MetaFrame Aquarium 11/16/09
I just stumbled across your site and have already added it to my
<Glad you enjoyed.>
I just purchased what was advertised as a "25 year old
acquarium" <aquarium> for $20. I unwrapped the box to find a
20 gallon chrome framed aquarium with a slate bottom in near perfect
condition, stand, hood and light combo. I did a little Googling and
found it to be a Metaframe, but I can't find anyone who sells these
<Mmm they have been out of business for some time. You are making me
realize my age, as I have bought and used these tanks in my early
years. Oh James, you have been here longer than you are going to
Any idea how much this tank would be worth to a collector?
<Whatever someone is willing to pay for it. A two gallon MetaFrame
is up for auction on EBay. The high bid right now is $6.51. Don't
quit your job, Kathryn.>
I love it and don't plan on parting with the tank anytime soon.
I'm a bargain hunter and I'd like to know just how much of a
good deal I got.
<Thank you for sharing your find with us. James (Salty Dog)>
