Does old water conditioner go bad?

[DK[_2_]]

I have a bottle of water conditioner about 4 years old. It doesn't list an
expiration date. Would it still be OK to use to treat my tank water, or do
the chemicals in it typically expire after a certain period of time?

Quit being so dam cheap go buy a new freaking bnottle its less than $5
at most any petshop.....and yes it can expire due to age or storage
conditions.

Hi DK,

A sealed bottle is 90% likely to be just fine (realizing that 72.7% of
all internet statistics are made up on the spot ;). If its been opened,
you run a greater risk that evaporation may have changed the contents. If
its been partially used, I'd definitely ditch it.

You could also call the manufacturer. They should know their own
product's shelf life better than anyone.

You might check here (there is an article about Aquarium water
conditioners):

Thanks, great site. I love hearing what the "pros" or long time hobbyists
have found to work best.

Do most of you find that the water conditioners that contain a slime coating
are necessary ... or only if the fish shows signs of injury?

I personally only use the slime coat ones such a Stress Coat or
Novaqua when there is injury, transfer, or rough handling and then I
try and apply it directly to the fish such as during transfer. I have
found much of the slime settles to the bottom otherwise.
For normal water changes I prefer to use conditioners that stimulate
the natural slime coat and contain electrolytes that aid in this such
as Start Right which contains allantoin and disperses well into the
water. In new aquariums I will use products such as Prime.

These products don't gunk up your filter?

I've used Stress Coat for years. The only other product I use is
Novaqua. Neither do anything to the filter.
It's not like they're gooey. = )

Thanks for that information. I've never used any of those products. Right
now I buy plain Sodium Thiosulfate by the 10 lb tub.

As long as the liquid was kept dark it should be fine.

I have never had any of these products negativly effect my filter. I
use Novaqua+ at every water change and keep Amquel+ on hand in case I
have a spike of ammonia, nitrite, or nitrate.

I have used stress coat from time to time at water changes. I have
never used Start Right.
