what to look for in new tank?
 

I hope the crosspost is ok; it seems more efficient than posting an
identical article twice.

Tomorrow I'm going to look at a 48 * 18 * 18 tank - it's very cheap
(£20, which is around $36, and a fair bit less than half price in the
shops). I think it's new - the guy selling it is a _serious_ fish
hobbyist, makes his own tanks and has taken voluntary redundancy to
start his own aquatics business - he says he's selling to clear out
space in his unit (and has lots of other "bits", too...) He seems like a
very genuine, friendly kind of bloke - he says he can give me a lift
back with the tank in his van, which is astonishingly generous (he must
_really_ need that space...).
What I need to know is, as he isn't an established business and as it's
the kind of rock-bottom price that probably comes with very few
guarantees, how can I spot a duff tank? I know too make sure all the
corners are flat to whatever surface they stand on, but would any faults
in the sealant be obvious? Should I look for anything else? - once I get
it home and fill it up with water it could well be too late. The kitchen
ceiling will not withstand 67 gallons of water coming through it!

Any suggestions will be gratefully received!

many thanks,

I would check the thickness of the glass used.
http://www.thekrib.com/TankHardware/...thickness.html has some
reference info on recommended glass thickness (48x18 = 120cm x 46cm =
10mm sides and 12mm base). Mine own 67g uses 9mm (or about 3/8").

Check for air bubbles in the silicone (a few small ones are ok). Check
for silicone imbrittlement (should be pliable and not hard like plastic).

Cosmetically, you can check for scratches. I'm not too keen on buying
home-made tanks, due to the expertise required (surface preparation and
the jigs), but maybe he knew what he was doing.

Do try to get a canopy and whatever bits he is willing to include. Even
gravel gets pricey in the LFS.

Oh, I wouldn't fill it for the first time in the house! Fill it
outside somewhere and leave it to sit for a day or two. While it's
full, check for any bowing of the glass, plus all the stuff Netmax
suggested. Newer tanks have a center brace in the middle of the top
frame to support the front and back glass. The front and side panes
should be attached on top of the bottom pane rather than around the
outside.

If he seems to know what he's doing, and has made several of his own
tanks, it's most likely going to be ok. But I wouldn't fill any tank
for the first time in the house.

Many thanks to NetMax and Cris - fantastic advice and I shall follow it
(why on earth didn't I think of filling the tank in the garden first? -
sheer brilliance, thank you.)

I'm not sure what the seller was doing prior to starting on his own
aquatics business; I get the impression he was in the trade. I'll find
out more when I see him. I'm really hoping this is a good tank; I have
far too many fish in a small one at the moment (my LFS, frankly, lied to
me about how many goldfish I could keep in a 13 gallon and failed to
tell me they might eat minnows. I'm hoping that they don't get big
enough to do so during the minnows' natural life-span) and I need more
space! I've never kept fish before this and I want to give them a good
home.

If filling the tank elsewhere (lawn, driveway, garage) make sure that you
have a very flat strong surface. With 600 lbs of water, the tank will
shift to close any gaps, and may cause damage & leakage which would
otherwise not occur.

and here is the problem I'm currently trying to address! I bought the
tank (it wasn't new or home made and had previously been used for
keeping chiclids, but it was being sold to make room for the tanks he
and stuff he now needs, I hadn't quite understood); the silicone seems
to be in good condition (squidgy), the glass is two thinner sheets
laminated together per side totalling 9mm for the verticals and 11mm for
the base, and I thought yes, I'll test it by filling it with water in
the conservatory - which, I now discover, doesn't have a flat floor.
Looks flat, but isn't. I think what I'll do is get it into the right
place (once I've got a stand for it) and fill it there. I'll need to
cycle it before I put the fish in (although I was wondering about
transferring the filter sponge to the new filter and hoping that worked,
but I really don't think I'll risk it), so that should give me a chance
to see if it springs any leaks. The seller is obviously a fish obsessive
(in a good way) and assured me it was fine.
Now I just need to be reassured that if it does leak, it will do so
slowly and in one place rather than exploding... And also I need to do
research into h.o.t. filters for this size tank... And also I need to
work out if I am in fact certifiably insane to want to keep goldfish
with a sand substrate and some plants (I have some that they don't eat)
and some weather loach... And also I need to work out if I want a
cabinet thing to go underneath or a metal stand... And also I need to be
very patient with my very small son as he demands every day for the next
few weeks if we can put all the fish in the new tank yet.

wish me luck.

If you haven't already gone pricing, you will find that the cabinet might
be your most expensive component. Steel stands are stronger, but kids
can climb them so they should be fastened to the wall joist to prevent
sway (depends on your child's age). Wood cabinets have the advantage of
being able to hide a canister filter (so the tank can almost go right up
against the wall) and it keeps your fish-stuff close but hidden
(child-proofing the cabinet door can be important with 'helpful' children
;~).

I'm on his side "let's do it mom". With your aged filter, you should be

thanks for your time, NetMax; I really do appreciate it. I know I can be
longwinded at times, and I also know I got off to a very bad start
keeping fish, so the advice is so reassuring. I'm actually quite
surprised at how committed I can feel myself becoming about the whole
experience - if I'd been told before I bought the little tank that five
or six months later I'd own a four foot tank I think I would have backed
out in fright! but it strikes me now that a bigger tank is actually a
much more stable environment and therefore much easier to maintain, and
to keep healthy fish in.

Take some gravel, put it in a little bag/pouch make of cheese cloth or a
nylon stocking. That way the buggies can hitch a ride to the new tank,
but you don't need to worry about cleaning up the gravel later...

It all makes sense, I just have no experience with it. I suppose the
panes are sealed along the edge so you don't have humidity leaving dust
behind. I'd imagine that there might be more refraction with 2 panes.
It's an interesting method to be sure, especially for overcoming the
expense and lack of availability of the thicker sheets of glass needed
for big tank. The jigging is more elaborate but your material costs are
lower (thinking out loud).

One cm would be more than the styrofoam could absorb. Alternately set
your plywood on four bricks (one per corner). It does not need to be
level, only flat. You could shim 1 corner if you needed to raise it 1cm.
You could also place the plywood on a level spot on the lawn (grass). I
must be more daring than most, as I just set it into a normal stand and
fill it with very warm water.

With an established UGF, then the gravel has a lot of good bacteria.
With any other type of filter, the gravel has more of the anaerobic
bacteria (decay of organic matter) which reproduces much faster than the
nitrifying bacteria you need. With moves, I do keep some of the old
gravel (filter bag in the filter, or old nylon as Donald suggested), but
I wonder how neccesary it is. I read this bacteria doubles every 20
minutes, so it should not be critical to have (but I question lots of
things ;~)

When you find something working for you, go for it. If normally sealed,
I find that the condensation on the glass cover underside typically
interferes with your ability to watch the fish from above. This will of
course vary according to the temperature difference in your home and how
sealed the cover is.

Internal canisters have their idiocincricies, which you already know
about with your internal Fluval. For Goldfish though, overfilter! I
would have thought that the AC300 powerfilter would be less expensive
than all the choices we discussed. For sand, you should not have to pay
much. The lid can be home made. Skip the polo lights as indicated.
That leaves the stand & filter. Your aquarium seller can't set you up
with a filter?

thanks for your time, NetMax; I really do appreciate it. I know I can
be
longwinded at times, and I also know I got off to a very bad start
keeping fish, so the advice is so reassuring. I'm actually quite
surprised at how committed I can feel myself becoming about the whole
experience - if I'd been told before I bought the little tank that five
or six months later I'd own a four foot tank I think I would have
backed
out in fright! but it strikes me now that a bigger tank is actually a
much more stable environment and therefore much easier to maintain, and
to keep healthy fish in.

Very welcome, glad to help. Yes, larger tanks are more self-maintaining,
and 48x18x18 is a very nice size (though I'm biased). It's not so big
that it takes 3 people to carry it or require floor reinforcements, but
it is big enough to do alot of things with it.

cheers
