How to remove nitrates without affecting phosphate?

Nitrate - 50
Phosphate - 0.1

How can I remove nitrate without stripping phosphates clean? I’m going to reduce feeding and do a 10% water change. I understand water changes will only remove 10% of my nitrate level so it’s not much. I have a skimmer and refugium in my all in one tank. Anything else I can do? Does brightwell have anything good I can dose with?

I would advice doing multiple larger water changes. Around 25-30 %. Water changes will drop your nitrates but will not have a very significant impact on your phosphate levels.

Dang I only have a 10 gallon bucket. And my tank is a 65g. I have a bunch of 5gal buckets but no way to heat them all at the same time. My living space is small

Maybe you could get a 20 gal rubbermaid bin
