Why are you so concerned with reducing if the tank is happy??
What type of food are you feeding
This is the root cause of your nitrates and phosphates
If you keep doing the same thing - feeding heavy - you will never reduce the nitrates and phosphates unless something can use them - I.e. start a refugium with macro algae
If you don’t have a nuisance algae problem and corals are happy I’d seriously stop stressing over water changes
Again can you tell me what you’re feeding the tank?
And is it possible to start a refugium up on your sump? Macro algae with use up the excess nutrients - mine does this to w
Also
I don’t take my LFS word as gospel
Plenty of people run high nitrates
This should not discourage you from adding corals
@fishguy242 will back me on the high nitrates thing!! lol
The key to a happy reef is consistency
I feed only frozen, I try to rinse it as much as possible… I do feed six to eight squares a day and a few nori sheets for the tangs. I’ve been cutting down on the portions to four squares and a couple of sheets of nori through-out the day..
