Took some water out to have it tested with a different test kit. Everything came out the same except for the ph being 7.8. There was a discussion about my lights possibly getting old but I know friends that run their MH for up to a year. I have been changing mine out at 8 months.

How much algae would I need to have in the tank to cause my reading of phosphate to be off?
