Re: High Phosphates

The tank with the high Phosphates is a 75 gallon tank.

120 Watts of light for 12 hours.
PH 7.25 - 7.5
Ammonia 0
Nitrites 0
GH 107 ppm
KH 131 ppm
Nitrates close to zero.  (The colors on the side of the test kit have 0,
12.5, 25)  I have lower than 12.5, but not quite zero.
I don't have an iron test kit so I have no idea.

I have 10 O'cats, 2 SAE's, 1 Pleco, and only 6 non-algae eating fish.

I think I'll clean test kit tube, re-read the directions and test again.
