Phosphates tested 0 in the big tank nitrates were around 40ppm I'm guessing (since the color chart for the nitrate kit is MISSING
) Didn't test phosphates in the little tank but nitrates were at about 2ppm. Calcium was off the chart in the little tank and Im sure it is the same in the big tank. I'm gonna switch back to IO. I'll get a bucket next weekend, along with a mag test kit. Thanks for coming yesterday, hope you and Carm had fun
