Water parameters and cycling issues

I have a 29 gallon tank and for 2 weeks now I have kept it at about 2ppm ammonia with household ammonia. Im still not getting any nitrites after adding bacteria. Heater has been on. Added a cup of my brother gravel to help the bacteria.
Ph 6.6
Kh 12
Gh 71.5
Any ideas why im still not seeing any ammonia drop or nitrites. I also find it weird i have such a high kh and low ph.

The odd readings probably have to do with the type ammonia you used. Don't keep dosing with ammonia. It should be a one time deal where you hit 2ppm and leave it be. No water changes.

Yeah i dosed to 2ppm and havent added any since. I used ammonia with no additives as well. Other wise when you shake it i see no bubbles.

It depends on how the ammonia compounds are structured. Give it a few more weeks and see if anything happens. I like Dr. Tim's ammonia for fishless cycles. Mine cycled in a week using their method. It's pretty cheap and might be worth redoing. 2ppm of what your using might end up being a heck of a lot stronger.

Hi CK,

Your water parameters are very odd. How did you measure them? First of all, pH. A pH of 6.6 is too low. You need to keep pH in the range 7.4 to 8.0 at all times. But, as you say, it's inconsistent with a KH reading of 12. And in what units is the GH reading? A GH of 71.5dH, for example, would be liquid rock and is unheard of!

Also, apart from your brother's gravel, what bacteria did you add? And what is the tank temperature?

All tests are liquid drops. Sorry gh is 4 i think that was a ppm reading of 71.5. I used top fin starter bacteria and top fin nitrifying bacteria.currently i am working on bringing up the ph. The tank temp is 78 degrees. I got 2 whisper 40s on it for now.

How would i get the kh down to reasonable levels but also bring up the ph?

Hi again CK,

OK, 71.5ppm GH would equate to GH=4dH. I am not familiar with top fin products. But that might be because I'm in the UK. I can vouch for the efficacy of Tetra SafeStart, which is excellent. Personally, I stay away from household ammonia. Dr Tim's Ammonium Chloride Solution for Fishless Cycling would be preferable. When you say that "All tests are liquid drops", which manufacturer's product are you using - API, JBL, Seachem, etc? This is crucial to resolving the problem that you are seeing. In what units is your KH reading? If that was also in ppm (like your GH), then KH would be a mere 0.7dH. If so, that can easily be increased. And that would also increase your pH. Your tank temperature is OK.

I use the api test kit for the kh and gh and doc wellfish for ph ammonia nitrite and nitrate. The kh reading refers to the number pf drops it takes to change colors from blue to yellow it took 12 drops which equals 12 °dkh or 214.8 ppm
