Is this the right type of ammonia? This is the best I could find after going to 10 places today. This was at Ace, they didn't have the Ace brand. I think it's the right stuff but want to know before adding it to my tank. Second question is, I filled my tank for the first time last night and dosed it with Prime. Do I have to wait 24 hours before adding the ammonia dose? I'm not adding any TSS+. Third question, I tested the water out of my tap, the ph is 7.4. Anything to be concerned about or is that OK for this cycle? What about beyond? Basically I don't know what the ph reading means. Fourth question. To figure out how much ammonia I will need to bring my 20g up to 4ppm I was going to figure out how many drops it took to get a 5 gallon bucket up to 4ppm. I added 10 drops and it brought 5g up to 2ppm. But here are the questions: It's OK that I added ammonia directly to chlorinated water to do this test, right? i.e. I didn't does the bucket with prime or anything. There is no agitation in the bucket. I waited a good half hour after dosing it to make sure it had "settled", but is it OK that I didn't mix the water up at all? Essentially I added the ammonia directly to the top, and then took a sample from the top too. Are my results reliable? Did the ammonia settle and disperse? Fifth question. To test water I'm having to use an eyedropper (I have 2). If I suck up ammonia-laden water with the eyedropper, is a good rinse sufficient to make it OK to use with clean water again? Sixth question. Similar to above, same question with buckets. Do I have to designate one as a "dirty water bucket" because it has held dirty water in it, and therefore might have traces of ammonia? Or does a good rinse out with hot water make it OK to use with fresh water again? Thank you thank you thank you! Still learning the ropes obviously.
