you should be adding ro/di water (ie. freshwater)
you should have an auto top-off unit constantly topping the tank off to stop stuff from getting "finicky". If you are just toping off every couple days then you may be swinging your salinity which is ****ing your livestock off. I know in my 50 gallon system i was evaporating about 1/2 gallon a day and i was topping off once a day but nothing was getting angry in the tank.
