Goldfish keep dying one at a time!

i cant keep goldfish alive! i have 4 small fantails in a 55 gallon tank with 2 aquaclear 70's, ive also added a liter of matrix bio support media between the 2 of them in mesh bags. my water tests perfect from my test kits and the lfs's test kits. they all last 2 or 3 weeks and succumb to a mysterious illness where they start to hide and have a long stringy poo. then at the end when there listlessy floating around the tank gasping theie fins show a little fraying. i use the proper amount of aquarium salt and do not over feed. ive treated with melafix and just went through a treatment of maracyn 2 but nothing im doing seems to work ive tried fish from different lfs but the same happens please help! the tank has been up and running for like 8 months and is cycled so i have no idea what keeps killing every fish ive put in here ive gone throug like 20! my symptoms are similar to the post "goldfish swimming on side"
ammonia 0 ppm
nitrate 0 ppm
nitrite 0 ppm
ph 7.5
kh 180
gh 160

Are you using test strips? They are notoriously inaccurate and I would recommend a liquid test kit.
You tank is not done cycling if you don't have any nitrates, you should have between 5 and 20. The fish could have a parasite too, which I believe causes white stringy poo, in which case the Melafix wouldn't cure, since it's for fungus not parasites.

ive tested with strips and taken water to the lfs it tests perfect both ways the lack of nitrates is due to the matrix biomedia in my filters and the live plants in my tank i only had noticable amounts when i began the tank before i started using matrix. i treated with maracyn 2 for the recommended course and finished 2 days ago since the last post my one fish died and another is starting to come down with the same symptoms that led to the demise of all the previous. ive even had times where a fish would only last 2 days and im getting tired of buying goldfish lol. so if all else fails and they all die will waiting a week or 2 clear out whatever was killing them and i can start again?

If it was me, after the last fish passes, I would disinfect everything and the tank, then begin a fishless cycle before I got any other fish.
I think most LFS use strips too...And like I said before, they are not accurate. You can spend $20 and save yourself alot of headaches in the long run! The liquid test kit I got saved all of my fishes lives.
7 of my new fish came with fungus. It almost looked like someone took a lighter to their fins and melted them together. I used Melafix for 7 days to treat and all is well now. And it didn't kill my bacteria! YAYY! But I lost 5 fish before I figured out what was going on.
Also, like I said before, it could be an internal parasite. Is the poo white and stringy? If it is, I would recommend using some sort of anti-parasitic food to feed the ones that are left.

The white stringy poo usually is a sign of parasites. Their are different meds you can buy, the problem is most of them are hard on plants. The best med I have found is Copper Safe but it will kill all of your live plants. You can google internal parasites and find out about some different treatment options.

Do you have charcoal elements in the filter? When you're medicating, you should remove the charcoal, because it will remove the meds. On the other hand, you could be over medicating to the point where you have a sterile aquarium. It's very unusual to have zero nitrate, especially when you have goldfish. You may want to do a few partial water changes to remove all the salt and medications and put in a cup or two of gravel from an established aquarium. Also make sure the water is fairly cool.

The way you introduce a fish into a new aquarium is also important. If they're moved too quickly, it causes a shock to their immune system and makes them vulnerable to diseases and parasites. The drip acclimation method (see our search engine) greatly reduces this shock. You should probably not add any more fish until the water quality problem is solved.

You can also buy the meds, and then soak the food in it. But you have to make sure your fish eat it quickly or the meds will leak out of it.

do you have any bubbles in the tank? it could be that your fish are not getting enough oxygen.

It may be an ornament because I lost 4 fish in 4 weeks because I had 2 plastic plants and we did what we were told to do and they still died

Do you plan on starting from scratch? Was there an illness or some reason the tank needs to be disinfected? Bleach is the best thing to disinfect- ratio of 9 parts water to 1 part bleach. Let everything soak for atleast 20mins (incl any decor, filter housings, bubblers, etcetc), rinse well & repeatedly. Allow the tank to dry in the sun if possible. If this is not possible, double dose dechlorinator & fill & let everything to soak for another 20mins & rinse again. Please ask if you have questions!

Do you have a heater? Goldfish need a warm tank so if you do, check to see if it's working

Goldfish are coldwater fish. A heater is not necessary unless theres extreme fluctuations in tank temps or the tank being kept somewhere very cold (ie, basement). Ideal temps are in the 68-74 range.

long, stringy, white poop is an internal bacterial infection. go to goldfish connection and get the medi-gold anti bacterial food. you don't have anything metal in the tank do you? don't over medicate. i made that mistake early on and killed every one of my fish. ii lost my voice for two weeks i cried so hard. i can certainly sympathize with you. i've lost more than i'd like to admit over the years and some i never knew why they died. i love my fancy goldfish and it grieves me to no end remembering the ones that i babied and talked to for weeks before they let go. i wish you and your fishishies the best.

Your feeding thim two much if your problem is with long stringy poo feed thim like one pinch evry serving and give thim pelits feed only 2 times a day it's ok to under feed thim but don't over feed thim or they will die if your already doing so try less a serving and see if that helpes a gold fish can live fore like a week without food but don't have a stomach to keep extra food

I would do a complete water change and get some Prime. Dose the aquarium to it's volume with Prime. Prime neutralizes ammonia, nitrite and nitrate but does not interrupt the nitrifying bacteria. You can safe guard your fish while cycling your tank. I would look up how long Prime is active in an aquarium and dose when it runs out. I've noticed goldfish do better with water changes if the replacing water is .5 degrees warmer. Other than that I would listen to John Arthur. He is a master of aquarium knowledge.
I am sincerely sorry for your loss. I hope with everything I have that things get better for you.

For testing the water use API MASTER YEAT KIT. It is very accurate. Judging from the long stringy poops, they are being over fed. Goldfish have a slow motabolism so they can skip meals. I would also suggest using Seachem prime. The stuff works great. Also, I would suggest getting a canister filter instead of a hang on the back because canisters have more space for bacteria. For the set up of an HOB or canister, you want to have ALL of you mechanical filtration coming first. (Coarse medium then fine) then you want all you biological filtration. I would suggest buying Biohome standard for HOBs. Do a 50% water change for 2-3 days. Good luck.

If i were you., i will separate the remaining fish and watch them.Sometimes there are infections in newly bought fish from pet shop. separate them from each others., removing the whole tank water., refill the tank and run a fishless tank cycle for a day or 2. use nitrate removing substance only when there are no fish in the tank., i think they can harm the fish., depending on types... Remove the things from the tank., i mean., plants.,rocks.,decorated things., etc., except filter and oxygen giving things. Be simple as you bought a new tank... I hope I could give u some help..Good luck pal.
