I also find it amusing that the number one most important measurement one can make for fish is for dissolved oxygen, yet hardly anyone mentions this and likely most do not have a meter. How do you tell that your fish are in an oxygen sufficient environment? By their happy behavior, or are they just coping with the environment you are subjecting them to?
BTW, presently I am doing 8% avg daily water changes and checking all parameters [including O2], as I have a young tank with young discus but I am working towards very minimal water changes, once I acheive a measurable balance. My municipality uses no chemicals and I heat the water in a tub.
i agree totally bleach water then de-bleach it then put in copper piping x years old then add it to our tank how many minerals and good things for fish can possibly be good for them to breath and we have to do lots of water changes so our plants thrive and out fish yet we have all seen people who do yearly changes and all have thriving fish long as they clean it out monthly
but no science talk but most scientist have one aim not many like the best
