Ok i have battled with this for some time and i am getting more and more frustrated when i see my sand bed get crap all over it within hours after a water change.
I have to clean rock once a week this cant be right
nitrate:15 (dosnt get above this most of the time is 0)
Cal: 375 and still rising
Filtration, there isnt much, its only a skimmer with stacks of LR
, but i dont have that much of a bioload at all.
the tank is 75gal.
I cant think of anything else you might need????
any help is appreciated.
