Bottoming out on phosphates and nitrate

[Sal Amato 90 gallon]

Hello everyone I have a 90 gallon reef 1 year old. Experiencing huge parameter swings when it comes to phosphate and nitrate. One day it is at 0.17 2 days later it at 0.07 on phosphate/ nitrates one day it 0.05 next day it 0 again. I am dosing daily Neophos and neonitro. I also have a few fish in as well .
Dkh is 8.6 for 8 months
Calcium is 445 for 8 months
Magnesium is 1475 for 8 months
anyone got any ideas

I see this is your first post, welcome to r2r.

First off, I don’t see that as huge parameter swings.. Would you better detail your tank: how did you cycle tank, live stock in tank, biological filtration?

Before you continue dosing hold on just a bit. What are you checking parameters with? This is one of the most important questions that need answering.

Do you have a ton of corals and frags in there? If so, eventually regular dosing matching their consumption is likely path plus removing some plus maybe adding more fish, increasing feeding until you reach a balance.
