seeing you don't know what it is you might as well try something. 25% bi-weekly is too small of a WC for you to have good tests in my opinion.
lets say you test your water parameters and it reads 60ppm nitrates after doing a 25% WC it will take it to about 45ppm... ideally you want the nitrates at about 20ppm. so if it's at lets say 40ppm you would need to do about a 50% WC. if you do only 25% the next time you go to do your "schedualed" WC it will be higher then the origional 40ppm, more like the 60ppm which then after the 25% WC you will 45ppm. and each time before you do a WC the nitrates will read higher then your previous tests.Rjrose835;2839557; said:How could not doing enough water changes affect the arowana so drastically and quickly?
