unsure as to what tank is what from your post
The tank I'm mainly talking about is my 40 gallon tank. I mention my 10 gallons tanks because the cycle seems to be stalled on both of them, meaning I'm getting 0, 0, 0, lower pH readings on them. I might try that product that Jamie recommended.
i would add ammonia up to 4ppm
That's where I've been trying to keep it at, but it often falls much lower than 4 ppm, at times when I'm unavailable to add more ammonia (work, overnight, etc. I'm not getting up in the middle of the night to measure my ammonia levels, lol!). But, for example, my ammonia levels this morning were only 0.25, and that was after dosing the tank last night with 4 ppm/s ammonia.
then i am unsure but could it be a case you went over 4ppm and caused it to stall if thats a possibility i would do 50% water change twice then start adding ammonia back to 4ppm
That did happen, actually, when I first started the cycle. I didn't know how much ammonia to add, so I added way too much and ended up with, like, 8 ppm. That shouldn't be affecting the cycle now, though, as I've done several water changes since. Now, I add very small amounts of ammonia at a time and set my timer for 1 hour. After an hour, I measure the levels. If it's below 4 ppm, then I add a little more ammonia. I repeat this until I get back up to 4 ppm.
i can see from test you have nitrates so its cycling or it was at some stage
When I add ammonia the cycle pretty much kicks in. It's maintaining the levels and the consistency that I'm having a problem with. The cycle isn't stable. It's kind of like a car lurching around a parking lot - stop, go, stop, go, stop, go. Etc.
what level do you let the ammonia drop too before you add more ?
Well, as I mentioned above, I try to not let it fall below 1 ppm, but sometimes it does because I'm not around to monitor it.
