Hi guys, so my SPS that i have in my tank has been looking a little dull and bleached recently, all my tests were coming back good but i was unsure about the phosphate as it is hard to tell with the colour chart so I invested in a HANNAH checker. I just received it and did a test and the result was 0.08. I no this is on the higher side and i also have a little algae problem which i guess is using up some phosphate so may even be higher. Can this be my issue to the sps being bleached and the algae problem or is it not high enough for that to be the issue. Thanks guys
