Thanks for the feedback. OK, it sounds like I need to add a little salt and some maxicrop with Iron and sit tight. Yes, they do use Chlorine and some of the water they "occasionally" buy is treated with chloramine.
I've been letting water I add sit in a 5 gallon bucket for two days before adding it to the system. I think I'll filter it first and add the bubbler as well.
eek STOP FEEDING At the high pH ammonia is MORE TOXIC. The high pH actually is good for the conversion of ammonia to nitrite. Your Ammonia is way high and so is your nirite. Some salt (like 1 ppt) can help mitigate the nitrite a little bit and make sure you have plenty of aeration for those poor fish!
However, is your tap water treated with anything? Like chlorine or chloramine? That is what can really inhibit cycling.
It is also possible that the repeated additions of acid causing the pH to bounce up and down has inhibited the cycling. See the bacteria have to adjust to a new pH slowly and if you keep bouncing it, you slow them down big time.
Once your system gets cycled, the pH will come down naturally so long as there isn't too much of a buffer in the system (lime stone or shells.) For the time being get some chelated Iron or maxicrop with iron to help the plants along while the pH is still too high.
I don't think your fridge filter will remove the minerals very well but if it's an activated carbon or charcoal filter it might help with chlorine or chloramine. to get rid of the minerals you probably would need to go with softened water (but with old fashion softeners that would add too much salt) or an RO filter.
If you are working with well water, I'd just say collect some in a barrel and add a bubbler and adjust the pH ahead of time to have it on hand for water top ups or changes.
I'v been struggling to bring the PH down on my system. My tap originally tested at 7.4 and after a few days, my water tested at 8.0. I put some PH Down into the system, and was able to get it to 7.8 after two days, but after that, would put some in, get it down to 7.6 to 7.4, but it always goes back to 7.8 in within 24 hours. Then I saw this post...
So I've tried testing the water from my fridge with an integrated water filter (Pure). I was thinking of dumping 1/3rd of my water a few times, but figured I should test it First this time. :-)
The water straight from the fridge is testing at 7.8, so I'm pretty sure it's my tap water that's causing the problem and not the media in my system (I originally put in "Pond stones" from Home depot and thought they were the cause). I've since swapped out over 2/3rd's of it with hydroton.
Anyhow, do you think the built in fridge filter will remove of the minerals in the water so PH down can be effective? Some of my plants are pretty yellow, which I believe is usually a result of low Iron. However, I know that a high PH also inhibits the plants ability to absorb Iron, so I don't really want to start supplementing until I get the PH under control.
Info on my system:
3 X 50G barrels (Approx. 120G+ of water)
1 barrel cut in half lengthwise. One half planted with hydroton, the other with approx 1/3 hydroton and 2/3 "pond stones"
Using Affnan's siphons for drainage
Current readings on my system:
PH 7.8
Ammonia between 4.0ppm and 8.0 ppm ( I have three goldfish, but I understand high PH inhibits the conversion from Ammonia to Nitrite as well)
Nitrite 2.0 ppm
Nitrate 5.0 ppm
Any help/comments are appreciated.
