Answer 1

Like other posters have said - never use anything except water when you are cleaning the tank. Also, you shouldn't "clean" the entire tank every time you put in fresh water. Since you have goldfish I recommend a 50% water change once a week. That means you can almost always leave your fish in the tank WHILE you are changing water. First take out about half of the water. It's best to use a gravel vacuum to do this because then you can get all of the junk off the bottom of the tank. Then put in your new water. Make sure the new water is treated with the right amount of dechlorinator and it is close to being the same temperature as your water - not too hot not too cold.

One more thing - if your algea eater "thingi" is a plecostomus, those really are not compatible with goldfish. If they attach themselves to the goldfish they will eat right through them, and that is not a rare thing.

EDIT: I forgot to add - do not change your water filter every time you change water - not even every month for that matter. To "clean" it, swish it aroun din some of the tank water you removed during a water change. Don't run it under tapwater ever, do not replace it unless you absolutely HAVE to. There are lots of beneficial bacteria that live in filters that eat the waste from fish and keep the water clear and healthy. That's why it's important to keep that bacteria in there!

Answer 2

the fish get stressed when you move them, when you completely empty the tanks water you expose contaminents and the "Clean" water is not conditioned for fish. Yes, I know you put drops in it and all, but the water still is not conditioned. If you want to start with all new water you need to let the tank air dry before adding new water. Add the new water and let it set 24 hrs before adding the filter. Add the filter with new carbon and let it run a minumum of 24 hrs before you add the fish. also you didnt address the issue of where were the fish when you were "cleaning" the tank. this may be an issue.

Answer 3

That ugly brown squishy stuff is what keeps your fish alive. It is beneficial bacteria that converts fish waste (ammonia) into nitrites, and then into less harmful nitrates. You are supposed to change 25% of the water every week to keep the nitrates from reaching a toxic level. If you clean out the tank too well, the bacteria are gone and the fish die from a spike in ammonia. Buy a gravel vacuum and use it to change some of the water every week (and don't get every single bit of poop out or the bacteria will starve before they can eat again).

Answer 4

ALWAYS make sure you dont just let the fish go directly into the water. Always let the fish get used to the water by floating them in a plastic bag in the water about 10-15 min. They will go in shock at the dramatic change in temperature.

Also make sure you are distributing enough of the chlorine drops and it would be a good idea to use stress coat.

Hope this helps next time. Sorry for the loss.

Answer 5

1. Buy a book on how to care for fish and read it!

2. Dechlorinate the water (see pet store for "conditioner")
3. Make sure the PH value is correct (see pet store for PH kit)
4. Make sure the water temperature is correct
6. Feed twice a day, but very little. It keeps the tank cleaner.

Answer 6

me 2 i have fishes, i wash my tank with soap and wash it well so as all of them go away....do u keep stagnant water.... becoz fish can't live in chlorine so u when u r planing to change ur water, leave ur water one day before....and take out ur fish with great care if one of their scales got damaged this can b also the reason 4 their death especially the gold fish...ya ur filer u should wash the sponge in side every 4 days at least...when u finished to wash ur tank , u put ur gravel, and then the water, then put a solution which destroy all the chlorine which is still present in the water. then put ur filter on then after one hour put ur fish in and now the c result.... and tell me. am sure no one will die again ...me 2 i have gold fish

Answer 7

when you sure its no soap involve, try tis.........
1.- wash you hands very well,

2.- not work with fish with any paint nails,

3.- not touch any fish with you hands or skin,

4.-use large nets for it,

5.- be sensitive about temperature of the new water.

6.-dont dry the tank with news paper or any print on it.

7. and dont change all the water, any time , just change
1/3 of the water each mont.

Be aware that any change in the enviroment of any fish is
very stresfull, and can get any reaccion from them

be gentle with any cahnge.

Answer 8

the question is what did you watch it with

never use soap products

take fish out of tank putting them in a plastic bag using water from tank


rinse tank out with hot water only

clean tank with hot water

re set up tank put treatment in it let stand for an hour then seal bag and put fish back in so their bodies would adapt to the new temperature before you re introduce your fish

take a sample of water to the pet store to check ph balance

Answer 9

what did you clean the tank with?
if there were any soap at all in the tank its a wonder that it didnt kill them all. did you put the chlorine remover in it the right way?

we have had koi and goldfish together for years and since we dont use soap on the tanks, we havent had that problem.

did they run around really fast before they died? that means that the chlorine got to them

Answer 10

There's no reason to "wash" a fish tank. The environment needs to be stable in order for the biofilter to survive.

Check the pH of your tap water. If it is very low, this could kill your fish quickly. Check out this website for all the info you need on keeping your fish happy: http://thegab.org
