If you are looking for a large, barrel-shaped container at a budget price,
here's a suggestion-
Most larger cities have a local brand of meat packer that makes sausage,
bologna, etc.  If they make pickle loaf, they are probably buying the relish
for the pickles in 55 gallon, plastic barrels.  These barrels are non-toxic by
FDA regulation.  When I got a couple from Russer Foods in Buffalo, NY years
ago, all I had to pay was the ten dollar deposit per barrel that Russer had
paid to the pickle people as a "bottle deposit".  It was cheaper to sell them
to me than to ship them back to get the ten bucks.  The dill and vinegar smell
lasted a long time, almost a year, but it never hurt the fish or plants.

The better solution is to avoid softer or flexible plastics wherever
possible. "Plasticizers" are chemicals (often soluble) added to a
polymer to make it more flexible and tougher. Hard rigid "plastic," (is
that an oxymoron, or what?) like acrylic and polycarbonate clear sheet
are usually pretty free of plasticizers.

Carbon filtering will do a pretty good job, but it also sucks up any
chelates that may be carrying necessary iron and trace metals for your
plants.

BTW "Tygon"-type tubing is prohibited in most hospital use for this
reason. Silicone tubing is used instead, to avoid the plasticizers.
Almost all aquarium airline is of the former type. :-)

Fortunately, most plasticizers that can easily be released are a bit
smelly, due to volatile components. When in doubt, use your nose.

Boil and pre-soak to remove the worst of them.

Don't use plastic plants unless you also use a carbon filter. :^)

BTW, plasticizers generally are *not* toxins. Read the definition of
toxic, rather than accept the news-scare versions of the word usage.
Doesn't mean they can't do subtle harm, tho.

"Tupperware" and similar food-use plastics *should* be quite safe.

Plastic toxin in tank

I purchased a RUBBERMAID garbage container on wheels that I was using to
store tap water in.  The water was conditioned by allowing it to age.
This water was then used to refill my aquarium tanks.  I used the water,
placed in your container, and after a period of time I smelled a stench
in my aquariums and realized that the garabage container was leaching a
toxin into the tap water I was storing.  I wish that they would notify
customers they use a plastic that is toxic.  Even after taking apart and
cleaning my tank I can still smell this stench which gives me a
headache.  I have assigned much time constructing and collecting fish
for my tank and I am very disappointed that an organization of their
status is using toxic materials for your product.  My plants are slowly
dying and I am afraid that the same will happen to my fish.

What should I do?  Any products I could use?  The fish seem to be O. K.
but I not purchasing fish for awhile.

Any suggestion would be helpful

Years ago, maybe 9 years now, I used to use the SNAP type kids swimming
pools for raising thousands of Corydoras at a time. I found these to be the
ONLY kids pools that could be safely used for fish.

Manufacturers aren't going to label their containers as having something
toxic in them if it isn't specified specifically for fish. These garbage
containers you got were probably manufactured specifically for 'garbage'.

Rubbermaid blanket storage containers, clear ones, were also useful in
rearing corys. These were not toxic.

One has to be very careful when purchasing something made of plastic or
other heavy plastic material to use with fish. Fish are more susceptible to
toxins in these containers than humans.

Talk to your pet retail stores that store bulk bird and small animal feed. I
purchased 3 - 30 gallon and 1 - 60 gallon barrel that one store that was
going out of business was selling. The barrels used to hold bird and small
animal feed and still, 3 years later, have the content names on the barrels.
It can't hurt just to ask them if they know where you may get ahold of some.
I use the 60 gallon for my RO water.

Freak Accident - Am I Dr. Kovorkian?

Michael,

It's not my stupidity, but about 2 months ago, I left my 29 gallon planted ram
tank in the "care" of my neighbor's teenage daughter.  The night before I came
home, the house sitter cleaned the inside of my tank with a 3M sponge that has
the green scrubber thing on one side.  She says within an hour of cleaning the
algae off the glass "so the fish could see out," all the fish were dead.
After I got home, I found the sponge, marked "Not for aquarium use." True, it
was brand new and had not been used with soap (just like I told her), but it
was treated with antibacterial chemicals.  Within a few days of the mass fish
death, all the plants lost all their leaves except for the Anubias, which hung
on to its leaves but turned yellow.  Now the leaves are all back, the plants
are out-competing the algae, the water is clear again, and the new rams are
spawning.  You may be a common place mugger of fish, but this little gal is a
gas chamber technician.

Holly
