Hi April,

no we are not upset, don't worry. Try to help, just brainstorming what could be wrong....

Hm, personally I am not a big friend of Ammo Lock. It sais it locks Ammonia and converts it into a non toxic form. But at the same time it gives you Ammonia readings. The good bacteria will still convert it to Nitrites. Those ones being through the roof now is a sign that your tank is in the middle of cycling. When those ones go down Nitrates should show.

Now How high is your reading of Nitrites?

What I'd do instead of cleaning the tank all the time add beneficial bacteria every single day for at least one week and let it find their home. They will settle mainly in the filter and some in the gravel (substrate)... and of course with every water change.

Can you get "Stability' there in Canada? It contains those beneficial bacteria and it is used to avoid "new tank syndrome". According to me I believe it is the better choice compared to StressZyme.

I'm just wondering why are you stil using salt? Is fishie sick? Just mentioning because goldfish are freshwater fish and IMO salt should only be used to treat illness. And sometimes as a tonic, not every time when you do a waterchange. But there are different opinions about this.
According to pH: goldies can take a lot as long as it doesn't go up and down like a yoyo all the time. 6.5 is a bit low for me, not far away that fishies will have too acidic water and start to dart arround. ( Acidosis ) I use those pH neutralizer blocks to keep it stable ( around 7.2 )

Basically what I think is wrong is the "over cleaning" because the beneficial bacteria are destroyed and cannot settle.

Hope this helps

Ah, ok, I see... perhaps I learned sth now, that salt lowers Nitrites I didn't know that... chemistry is amazing ...

Ok, in this case I believe it was wise to do a water change. Keep adding Nutrafin Cycle every day, I assume it is much the same like Stability ?
Monitor the Nitrites, change 50% of water if necessary every (2nd) day. Nitrates will start to show too. If they are higher than 20ppm, continue with your water changes.

Most important is though to add those beneficial bacteria.

How is Mr. Tailer doing?

Other than that you've done the right things IMO

Lovely to hear Mr. Tailer is ok, and yes this is very normal behavoiur. Ours do it all the time.

I am not sure if I'd change the water twice a day... or did I misunderstand?
Once a day is fine, about 50% and yes, add those beneficial bacteria, this is the main thing.

I don't know about the salt details either, I may investigate about this.
But just out of my tummy-feeling I think I'd rather don't use it as much..... , I dunno in this case, to be honest, so maybe Nossie, Andrea or Mindemae know sth about this issue.  Hmmmmm, scratching my head and got wooden splinters under my finger nails, LOL

OMG, this is so strange.

Did you test your tap water? Hope there is nothing in there....
your tests are they liquid ones? Or paper strips?

April,
I real think if Mr. tailer is acting fine, but you are showing a high reading of nitrite that it is a false one and you should do nothing. MotherNature will soon correct the problem with helpful bacteria.  However, if he is stressed consider 1) changing some water to dilute the nitrite, 2) adding ammonia-absorbing chips to the filter media such as zeolite, 3) add a bit more ammonia beneficial abateria to the filter media, or, 4) adding 1 tsp of aquarium salt per gallon of water to neutrilize the toxicity of the nitrite.(Salt DOESN'T remove nitrite, it only makes it less toxic).
I agree with Hanna, the more you fiddle with the water the more time it is going to take to cycle.  
AND 1 further note: DO NOT ADD ZEOLITE TOTHE FILTER IF YOU ARE GOING TO USE THE SALT)  The salt will "clease" the zeolite so ammonia will leech back into the water.  My sister uses that Nutrifin bacteria and it gave her a real high reading on the nitrites so I am thinking it is a false reading. If you feel you have to change the water a bit and can't wait only change the most 10% at a time until the tank is cycled which could be another few weeks.  You don't start doing regular water changes until the tank has cycled all the way!
Good Luck, keep us posted!

I think if you are going to use your tap water then buy a different water conditioner.  Do you have a petstore near you that sells Aqueon.  Aqueon water conditioner neutrilizes ammonia and nitrites.
I guess you could buy bottled water.  Nitrites aren't as harmful as ammonia is altho it is still somewhat toxic.

Yeah I would put water condtioner in.  It will help at least coat the fish and protect his slime coat.  It also will remove chorine or chloromines.

Thank you Mindemae   I just switched out 6 gallons and treated it precisely with the water conditioner, waited 30 minutes and scooped my squishy friend Mr. Tailer back up and into it. He seems brighter already! Tested everything again and now are as follows;

Nitrites = 0.8
Ammonia = 0.50 still but rendered non toxic
pH = 7.0

What a nightmare! I never dreamed that the water flowing thru a Brita tap filter (that is new) would contain such extreme chemistry changes. The past few weeks the city water has been loaded higher than the norm so thank you Hanna for asking as I simply assumed it was good quality coming thru.   And I will pick up the Aqueon as you suggested Mindemae 

Well, I just coudn't think of anything else anymore  but test the tap water.

Glad Mr. Tailer is fine .

Now it is important to let it settle, monitor the water chemistry and only do waterchanges when necessary. And always add those beneficial bacteria.

You do realize Hanna that you probably saved my little fish friend by suggesting that I test the tap water. Today after yesterdays change of 6 gallons, the nitrites are 0.1 and for the heck of it I tested that brita water again and it is off the charts turning the test sample dark purple! I'm throwing the thing out as I can't bring myself to drink it when the stuff coming directly out of the tap is so much better! Nossie I figured out that the tank I have is actually 10 gallons so in regards to the 2 tbsp of aquarium salt that I added yesterday, and having changed 6 gallons of that 10 in the tank, will the remaining salt be an issue for my fishie? I am so grateful to have joined this forum or my little friend might have perished. Thank you all for your wonderful support and advice 

I already said that  Hahaha nah I'm just kidding about the angry face I don't really get those tap water filter thingies, I'm fine just drinking tap water and now I'm even more convinced after those test results of yours 

Aren't their drops that take away amonia, nitrates, chlorine and chlorinames. I use them and all the chlorine is gone in minutes!
