Nutrient consumption extreme

[Mechano]

Is there any bulk options ppl are using for nitrogen and phosphate rather than buying millions of bottle of fauna Marin P and N?

My system sucks up the nutrients like a pig. I don’t even run a skimmer anymore and regularly crop chaeto and caulerpa, but still using the filter roller(should I remove it and go back to socks )
I feed heavy in my 250 system , but it’s unreal how much nutrient is being used up daily.
The only pest algae is coralline(which isn’t a pest in my eyes)

Any help appreciated , thanks

I should also note that my system is stocked quite heavy with fish as well.
DT has:
7” chocolate tang
5” sailfin
5” purple tang
8” foxface
3” melanarus
2.5” leopard
2.5” fairy wrasse
Flame hawk , clowns , algae blenny, coral beauty, talbot, a few neon gobies , 1 sixline, 2 mandarins, 3 dart fish
Refugium has:
2 skunk clowns
Sixline

Try shutting your refugium down?¿ it may be eating up all the extra nutrients, even though your trimming the algea

Yeah. Seems to be one of two things.
Either the refugium or maybe the roller mat cleans too well. No other explanation that I can find.
Gonna have to play around delicately with this.

Cut down the refugium a lot. One packed with chaeto, mangroves and an algae scrubber is how I ran my 0 water change system for years. It does suck alot of P and N out, more so then any specialty filter ever could. Feeding them fishies heavily helps too.
