bucket today and start doing them as you suggest instead of 10% once a month straight from the tap. Feeling much happier about all this now, thanks again!
Straight from the tap? Were you using any type of dechlorinator when you started the tank? If not, it is absolutely amazing you still have a bubble eye! That would be a super fish right there, lol. Regardless of what you are using now, I will take this as an opportunity to recommend seachem's Prime. It is super concentrated so a bottle lasts forever (2 drops a gallon to treat, so you would only use about 30 drops a water change) and it neutralizes chlorine and chloramine, as well as temporarily neutralizing ammonia nitrites! It really is the best one out there in my opinion.
