How do I raise my phosphate?

[Burrito]

Back in early December I bottomed out on phosphate and had an outbreak of Dino’s. I never want Dino’s again. Lol. I’ve been able to raise my numbers and but it seems I keep seesawing my PO4. See chart below.

My export methods consist for a 100g dt with 31g sump. (Figure about 100g total water)
Healthy fuge of cheato, 11pm-8am reverse photo period lit by kessil h160
Nyos 160 (beast of a skimmer) 24/7
Automatics water changes nightly of 2g
~3 8x8x1 plates of marine pure
36w uv 24/7 ( added this after Dino’s)

I have 14 fish and feed 1 frozen cube, 2 sheets of nori, and 3 pinch’s(auto feeder) of pellets a day
Tank shot

Can anyone suggest a tweak to anything I have going to increase or rather stabilize my PO4 ? I would love to hover in the .05 range

I have minimal algae (but do have some)in the tank and can’t get a NO3 reading due to the fuge.

Huge thanks

Reduce the amount of consumption and export.
The fuge and Marine pur blocks and auto wc.

The wc is most likely killing you no3 levels the most.

So reduce everything?

I’d keep the skimmer but skim dry , trim the cahato and or reduce the time. The blocks are full of hungy bacteria so.

Myself I’d probably look at the block s first. Easy to remove , clean and use later.
Just do one at a time what ever you do.
