Help! Green Hair/Bubble Algae

[nosurrender00]

Help needed please! I have a 6 year 50 gallon tank that has been lucky enough to never have a Green Hair/Bubble Algae outbreak and unfortunately I do now. I’ve done nothing differently now than I have in the past 6 years, lighting hasn’t changed and on the same timer. Any ideas what’s causing this and how to get rid of it? I bought a lawn mower Blenny and Emerald Crab, but not seemingly doing much to help.

My parameters are:

Phos .03
Alk 8.8
Nitrates 0

Do you get your hands wet everyday with manual removal? You need a diverse cleaner crew of about 25 snails. Including a few turbos and 2 or 3 tuxedo urchins. Cut lights to 6 hours with blue and uv only no whites. Increase magnesium to 1500. Your bottomed out nutrients levels will lead to other bad things to.

Yeah I agree with above. Get a firm bristle brush and scrub every crevice you can get to, and get at least 5 emerald crabs (ask for females if you can get them), and if you can manage it, get a small rabbit fish.

Thanks for the advice guys, unfortunately there is very little manual removal I can do based on the height of the tank and cannot reach the bottom half. I’m still confused with what would be causing an outbreak when my nutrients are very low. I only run blues as well.
