0 phosphate.... uh oh

[Bill92]

Hey everyone

So i have gha basically everywhere, i removed maybe 75% of it manually during the last water change which was around 3 days ago

I Bought some aquaforest phosphate minus because my phos was abit high

My parameters are

Nitrate 15
Phosphate WAS 0.12 (last night)
Phosphate is now 0 (this morning) !
Using hanna ulr and salifert to double check

Ive obviously added to much, the recommended dose is 25-100ml for every 100l / 27gallons
And i added the 100ml per 27gallons under the direction of 2 lfs
So after testing 0 this morning, ive removed the phosphate minus from the media bag it was in and placed it aside

So 2 questions

Should i half the amount of phosphate minus that was placed in originally and put in back in the sump ? After i get a reading ofcourse

Second question
If i only put half the amount back in the tank can i store the other half for the next time i need to change the phosphate minus or do i just bin it

You should leave out the phosphate minus at least for a little while till it starts to get high again. Start feeding some more to get it up.

Do u know if the phosphate minus that was used, can i reuse it, when the time comes or does it get ruined once submerged in saltwater
