Hi guys,
my tank has been running at undetectable phosphates for 2 years. For that time I have always struggled to keep good sps colour as they have been starved for nutrients. I have started dosing phosphates and nitrates to get my levels from 0 to something. I have dosed enough phosphates into this tank to increase the levels by 0.25ppm of phosphate. I dosed this over one week and at the end of the week the highest reading I got was 0.01ppm.
Is this normal as I know phosphate can be bound in rocks so is the opposite true where there can be no phosphate bound as there has never been an phosphate in this tank.
Many thanks for any help
