First off, I'd like to say I am already educated in general fish keeping and know about cycling the tank and everything now. My current problem comes from when I was not as educated. I was planning on getting a small above ground pond and decided to look up a good way to introduce the beneficial bacteria. I found a website that told me to put in a lot of ammonia every single day until the nitrites started going up, etc. I bought the API Freshwater test kit and of course my dumb brain decided not to read how exactly to test the water. I tested it incorrectly and ended up pouring in almost a whole jug of ammonia into one of my 27 gallon tubs since no ammonia was showing up in my tests. Yeah, I know. Absolutely stupid. Once I finally decided to read the instructions and redo the test, my ammonia was so high that it turned black. I did a lot of water changes daily and it stuck to 50 ppm since that time. I got my pond a couple weeks ago and thought the ammonia wouldn't really transfer over there with my 2 huge sponge filters, since it's 110 gallons for 3 Butterfly Telescope Goldfish, 1 small Black Moor, and 1 small Fantail. Plenty of space! For more than the past month, it's still been reading 50 ppm. I still do water changes now frequently and use Seachem Stability as well as Seachem AmGuard. No change. On top of that, my fish have now contracted Ich, because I didn't QT some new plants I added to the pond. I have already got Seachem ParaGuard, so I'm fine in that point. I just have no idea what to do with the ammonia situation!!! Please help!!!!
