The effects of Bacteria bloom on PAR

[kaifish]

Just got my hands on a PAR meter to check my lighting and as luck would have it the morning before it arrives I’ve got cloudy water. I’ve done a couple water changes and ran some carbon but it has only gotten slightly better. Would this radically effect my readings or will I still be in the ballpark

It would depend on how dense the bloom is. It could filter some Par.
