Does Marinepure media reduce phosphates?

I had 4 of the small 2x2 blocks in my 65g system for a long time. Seemed like no matter how much I fed, my Phosphates would never go above .08 or so. They were actually usually in the .02-.05 range. And that was with heavy feeding.
A month or so ago, I removed them and put them in my nano (the idea was to move pods over for the mandarin)

Since then, my Phosphates have been steadily climbing. About .30 now. No other changes to the tank.

I'm considering adding 2 of them back to see if the pO4 comes back down a bit.

Anyone else experience something similar?

Evening,

I have not used or researched that media much. From what I understood it does not contain anything that would bind the Po4. They could have been helping thru the overall nitrification cycle.

Maybe some one tonight will know

Ya know what? I think I figured it out. I did reposition several corals onto new pieces of fragzone rock rubble. I suspect the phosphates are leeching out of the new rock.
Didn't even think anything of it until just now. I guess that counts as a change to the tank!

If marine pure is aluminum oxide, then it removes phosphates. Phosgaurd by seachem is aluminum oxide. Iirc marine pure is aluminum oxide.

So what is the conclusion?

Is it safe and better to remove media blocks?

Are they really doing anything past the beginning cycle?

Do they need replaced every so often?

I guess these are my questions.. anyone?

This thread was about phosphate and Marinepure. They are nearly unrelated.

They can act as a place for nitrification. Is that needed? Not usually in a reef tank with live rock and sand.

They may also act as a place for denitrification. is that useful? Maybe.

Unless they are crumbling, they do not nee periodic replacement.
