Stalled in fishless cycle

philly27

Okay so im doing 2 fishless cycles using pure ammonia as my ammonia source. its been 6 weeks since i set up both these tanks and about 5 weeks since i added my first dosage of ammonia which was around the end of march. it took about 10 days for the ammonia to drop to zero and nitrites to appear. i kept adding ammonia daily based on my test results. everything was going good until my ammonia in both tanks drastically slowed down being removed. so after reading Mattgirl(s) "symptoms of a stalled fishless cycle.." i think both these tanks have stalled. any thoughts?

tap water: .50 ammonia, 0 NI, 0 NA, 6 degrees KH, 8 Degrees GH, 8.2 pH

29 gallon fishless results as of 2pm 4-28: 6.4 pH, 1 Ammonia, .25 NI, 160+NA.
10 gallon fishless results as of 2 pm 4-28: 7.4 pH, 1 Ammonia, 0 NI, 80+NA.

I do have a cycled 29 gallon and 5 gallon tanks, but those bad boys are relatively new and i do not want to disturb their cycle, as it was super stressful doing a fish-in cycle, but all those fish are striving and im happy hahaha. The only thing i did to the fishless cycle tanks was add some plants and moss within the last week. I think my waters minerals have been used up. should i do 50% WC in both tanks?

i appreciate you taking the time to read this far and offer up opinions and solutions! you really dont know how instrumental this forum/website has been in my understanding of anything i have concerns or questions about. so thank you, once again!

JeremyW is correct. It is time to change out at least half the water to get these cycles moving forward again. I would either change out more than 50% or do more than one 50% water change on the 29 gallon tank to get the nitrates down and also get the pH back up.

Once done get the ammonia in the 29gallon up to 2ppm and 1ppm in the 10 gallon.

good (late) afternoon. So after 24 hours after doing 2 major WC's and redosing each tank i have the following numbers.

29 gallon: .25 ammonia and less then .25 nitrites.
10 gallon: 0 ammonia and zero nitrites.

im going to re-dose the 10 gallon, then check in 12 hours if the 10 gallon tank is officially cycled. should i re-dose the 29 gallon? or should i wait till it trickles down to zero ammonia ?

thanks a million

I would go ahead and add ammonia to the 29 gallon.
