I'll give all the background information as to allow you guys to have all the info you need to assess the situation and let me know what to do:

I had a 30G setup with some cichlids. The filtration I had was a Penguin 350B, but instead of the typical blue floss filter cartridges, I had it setup like a canister; a sponge for mechanical at the bottom, a filter sock with ammo-carb in the middle, and a filter sock full of seachems bio media at the top. This was on both sides. I also had a TopFin 30 setup the same way running as well.
My ammonia always read .25ppm and nitrites were always between .01-.05 ppm. The fish, however, were happy, and were breeding...

I got a hold of a 55g and wanted to move the cichlids into it immediately...so I syphoned out the water from the 30g, keeping about 60% of it to put back into the 55. I bought a fluval 405, and after reading tons about filter media, decided it was uncesscary to put any carb or ammonia chips in there, so it's loaded with bio media on top of fluvals prefilter media. I also added the bio media from the old setup into the new setup.

So the tank is up, and postioned, and I add the water from the old tank. The rest of the water is filled in from the garden hose (this tank is in the garage). I tested the water coming in from the hose, no ammonia, no nitries, and a little chlorine as expected. So as Im filling the tank, im sprinkle in a couple capfuls of prime.

I didnt use any of the old substrate, I wanted sand, so thats what I put. I did however add alot of the rocks that were used...and added even more "new rock" that I picked up from the garden (landscape rock).

So the tank is setup, I add a powerhead and than make sure all the connections for my fluval are tight, and start it up. Perfect. I let it run for a couple of hours and than add my fish to the tank...

A couple of days go by, and I come home late at night, to see my fish gasping for air at the top of the tank...I panic, and throw in some prime (I assumed it was ammonia). The fish end up dying, and Im bummed. I take the fish out, and test the water, the nitrites are through the roof.

This was a few weeks ago. Since than, Iv done several water changes. I also ended up throwin in some goldfish (after reading articles on the nitorgen cycle) as to help with the cycle. I started with 6 tiny gold fish...and that same night after I put them in...3 disappear, literally. I took the other 3 goldfish out. Next morning I search thorughly, and find nothing. Long story short, it ends up the gold fish were sucked up by the powerhead and basically spit out into the tank. Ever since than (a week and a half) the Ammonia has been a constant 4-5ppm. I dont get how.

I have noticed, after learning to do water tests everyday instead of every few days, that the nitiries are slowly creeping up. About 3 days ago, nitiries were maybe 1.0ppm, possibly a little more, but today I check and they are around 3-4ppm. Ammonio is still, amazingly, 4-5ppm and I have no idea how...

So any guesses? I removed all the dead goldfish from the power head. I sifted the sand and found nothing. With Ammonia at 4-5ppm and Nitrite at around 3ppm, any guesses as to how much longer the cycle will take?

Thanks in advance.
 
I'm gonna have to make a trip down to Pearland for some cigars, huh? Swweeeet! Anyhow, if nitrite & ammo are both that high, your cycle is going perfectly. Just keep adding your bacteria supplement (stability, biozyme, cycle, etc.), but dont add Prime or Amquel. Dont add fish yet, either. As soon as you get more than 10ppm of nitrate, start throwing a little fish food in there to rot every day for at least another week. Once you get to 0 ammo, 0 nitrite & about 40ppm nitrate (or higher), IMMEDIATELY do a big water change & add a small fish. If he lives, keep monitoring & stock the tank slowly & enjoy!
 
Sweet, thanks for responding. I've been using Cycle as well as another one that I cant think of the name. My Nitrate is over 10ppm I believe...or atleast thats what the test strips indicate. However, like I posted, my Ammonia is STILL high at around 4-5ppm. Should I still add fish food?

Dude, you are more than welcome to come by and have a cigar on me. Im surprised I even ran into some here from the Houston area...this forum seems to have alot of east coast or west coast...and nothing in betweem.

What part of Houston you in? Feel free to contact me...

I live on the Northside & work in Katy. Free ceegar?... Im there.
Your cycle probably still needs at least another week or 2. Once the ammonia starts to drop the bacteria can starve, so just add enough food to keep about 0.5ppm ammo in the tank until you're finally ready to add the first fish. After that, never change/wash the media in both filters at the same time. Just change one & wait a week or so before replacing the other so you dont throw all the bacteria away.
 
yea feel free to stop by, we can chat it up about fish, cigars, etc...
Just give me a heads up if/when you come so I can be sure Im there..saturdays are always good cause im there all day staurday.

I guess ill keep watching the ammonia and nitrite levels and go where it takes me. Thanks again for your input..

Any ideas of how/why my tank is sustaining a level of ammonia so high after removing the fish so long ago?
 
Yea, like I said, Im not complaining...just boggles my mind that its so high after so many water changes and after removing the cause of it.
 
Checked the Ammonia this morning, doesn't seem as high, but still in the 2.5-4 range. The shade differences are really hard to compare to the actual liquid results.

I'll post updates as I go...and hopefully pictures when I get my new beasts in there :)
