Aquarium medication ingredients:
First of all, please take
a look at the ingredients in your medication. Since there are soooo
many meds out there it is impossible for us to list and keep up with
new ones and every one. It is the owner's responsibility to check the
packet for ingredients and expiry date. Most fish meds
will contain a combination of the ingredients below and under law
all should be listed.
Secondly, there is a list
of medications Andrea and others compiled in Treatments,
please refer to that in tandem as it contains usage directions and other
useful points not covered here.
Third, while medications
can be useful and life saving if chosen carefully, sometimes we are
apt to use the wrong one (or wrong dosage or with other contraindications
present) and this can harm the fish. A good plan to avoid this is to
list all the symptoms your fish has and consult Mods/helpers/other members
and similar case threads for best diagnosis and choice of meds, paying
special attention how to use them. Remember, in the case of all meds
used -any stressors like low dissolved oxygen, changing or acidic pH
or any ammonia present can be a lethal combination worse than the disease
itself sometimes. Always water change and then check params+ pH before adding meds.
Remember too, the more active
ingredients in the medication (number of) the more potentially
dangerous or powerful the medication usually is.
Sooo many precautions, not for the novice.
Use gloves. Keep in well ventilated area. In the dark. NEVER in fridge.
Removes 70% of DO in water so weak fish may die of suffocation.
Huge increase of toxicity at high temp above 70F.
NEVER use any product containing formalin with salt, it is toxic. Do not use with salt.
Formalin can sterilize bettas and smaller fish.
NOT effective on bacteria, only ectoparasites.
Kills many bbs.
or any other so called greens (e.g: aniline green, basic green
4, diamond green B, Victoria green b etc). Also a registered carcinogen
and banned for use in fish food fish. Toxic dye, toxicity related to
pH, temperature and DO levels. More toxic in high pH. Does kill
bacteria as well as parasites. Kills all bbs. Higher dose needed for
marine tanks. Loaches and tetras need just half doses. Do not use with high levels of salt.
Can sterilise fish. Top breeders do not use it for high quality potential
breeding fish.. It's a disinfectant, a dye. It can
be used with 0.3% salt which is an
advantage but it will wipe out all bbs. They are very sensitive to it.
Can also be mixed with green and/or copper.
Meth Blue. . Used in many
topical applications. Again all the precautions of the other toxic dyes.
Kills bacteria and parasites.
Can be used with salt. Can be mixed with most other meds inc. antibiotics.
Many have used this to good effect and it can be very effective and
is the best treatment for velvet BUT coppper can NEVER EVER be
used in acidic or fluctuating pH. It can kill fish very fast in soft
or low kH water. Works on parasites mainly. It is immunosuppressive
so should only be used on fish that are active and not really really
sick. Cannot be removed well with carbon and should be removed via
a 100% water change. Not
to be used in reef tanks/with salt or with snails.
Toxic if used past expiry date be careful to check the date.
Melafix: Tea tree oil and Pimafix:
West Indian Bay tree oil:
Can be used with anything. But never
longer than 8 consecutive days. These are oils so some say can clog
gills and extensive use should probably be avoided if fish has weak
or impaired gills.
Absolute contraindications ; antibiotics.
Tetracyline antibiotics in the water should not be used with salt or in high gH.
Salt and high gH makes them ineffective
because tetracyline binds with calcium and magnesium making them inactive.
They are ineffective in high pH/over
Tetracylines should be used alone and
not mixed with any other meds (except in med food and *).
Maracyn 2/minocyline is a synthetic tetracyline.
Tetracylines can cause anemia.
Maracyn 2* can be mixed with Maracyn/erythromycin.
No other tetracyline meds should
be mixed with other antibiotics in the water.
All tetracylines are light sensitive
and will turn the water brownish as they decompose. Water should be
changed if you see this happen and the tank should be covered and in
dim side light only when using..
not be used with Medigold food but
can be used with Metromeds..
Eryhthromycin/Maracyn treats mostly gram positive bacteria and
is not well absorbed in the water. It can be administered by injection
or in food and can be used with minocyline (and with rifampicin to treat
not be used with Medigold food
but can be used with Metromeds..
All other antibiotics used
for goldfish can generally be used with low salt. Some antibiotics like
Kanamycin are actually more powerful
and effective when used with low
salt. However, remember that salt is not necessary with antibiotics
that are chosen and dosed accurately and can be an extra burden on fish
and bbs. Salt should not be used in fresh water aquariums on a regular
Using zeolite/ammo chips and
When using any of these do not use salt. Salt will release toxins back into the water.
Can be added with anything at the
low recommended dose of 1/4 teaspoon per 10 gallons.
In certain special and rare circumstances
it can be used with regular salt.
