Okay, so I set up a small tank (5 1/2 gal) in about....Mid January I had a lot of issues in the beginning because I took some advice from the fish people at Petco and tried to plant the tank. To leave out the long details it didn't work and I just ended up with dead plants and high levels of ammonia and everything else. So I scrapped the idea of a planted tank restarted and went through the cycling process with 2 white cloud danios.

I had a bunch of issues but finally everything is normal except for a presistant Nitrate problem. I use quick dip test strips to test my tank and so I don't know exact lvls just that everything but the nitrate lvls read normal and safe. The Nitrate lvls read off the scale. I have one fish in the tank,( a white cloud danio) I have no plants, just a heater that keeps the temp normally around 74-78 degrees and a Tetra whisper filter that able to handle tanks of up to 15 gallons plus gravel, a rainbow cave thing and one fake plant.

I've been doing water changes with a grav vac every week the man at Petco said to only do about a 20% water change every week and so that's what I do. But the Nitrate lvls are not coming down and I am out of ideas. The fish people at both Petco and Petsmart don't know what is wrong and don't have any more ideas so I'd like to know if anyone here has a suggestion or an idea of what I can do to fix the issue and maybe what could be wrong with the tank...? I've had someone suggest that I buy a algae eater and that might help but someone else said that wouldn't do anything for my issue, so...any ideas?

All I want to do is get this set up so I can put my beta and white clouds back into the tank...
 
The algae eater won't help. When you say nitrate's are off the scale, can you be more specific? Have you tested the nitrates in your tap water? How much are you feeding?
 
plants do help nitrates but I'm guessing you have low light and most of the plants that do okay in low light don't suck up nitrates fast.

you may be able to bump the light a bit but it depends on the light fixture.

that said..what are the nitrate readings? you may want to invest in a drop test kit.

get a reading from water source too.

nce you establish the source is not the problem..just do several 20% water changes during the week and re test
 
Get a liquid test kit and check for nitrates in your tap water.
 
I have had the source tested and it's all fine. The chart on my tester quick dip bottle says that the Nitrate is above 200. But honestly I have no idea what that means, all I know is it is pinker than the pink spot that has 200 written above it.
 
Oh, as to the amount I am feeding I only feed enough that is eaten within a minute. once a day.
 
Fine doesn't say much. Also test strips are notoriously inaccurate. Get a liquid test kit for nitrate. You will get much better results.
 
oh and no need for a heater if its only the white cloud, there coldwater fish.
