Help, High phosphates low nitrates

[bdouglas119]

usually my phosphates are around 0.1ppm and nitrates around 3-5ppm. Recently my nitrates bottomed out and is measuring around 0-0.5ppm with my Nyos test kit. Since that happened my phosphates have doubled to 0.21. Yesterday I did a 30% water change and the phosphate levels didn’t change. I’m checking them with a Hanna checker.

I ordered brightwell phosphate E liquid phosphate reducer and brightwell neo nitro to add nitrates. Any other suggestions to get things back in balance ?

You could look into adding nitrates. Read about the Redfield ratio. And a water change.

+1 on dosing nitrates

While you wait for your order. You could run GFO if you have that is. Just have to really monitor P04 with GFO. Then feed more frozen foods to bring up N03.

If after a 30% change there is no difference in phosphate then is there a chance there's an issue with your test? May be worth recalibrating and trying again?

Thats a good article.

I dont have any GFO at the moment.

My AI Prime Fuge light usually runs opposite to the display lights, i turned them off last night and removed some cheato, i think the the source of the problem was my fuge becoming to efficient. i feed frozen once a day and pellets 3 times a day. My cheato was growing like crazy.

Water changes won't have much of an effect on phosphate levels...GFO will. I recently used it to drop my phosphate levels.

I was at 0.4 in my 80 gallon system. I used 8 tablespoons of GFO in a reactor, replaced every other day. In 10 days phosphate went from 0.4 to 0.01.
