I've been having hair algae issues in my 20g long for almost 2-3 months and I can't get rid of the stuff. My tank is about 8-9 months old. I've tried manual removal, more frequent water changes (and my nutrients are nitrates <20ppm and phos <0.25ppm, this is how they've been since the tank has cycled but only recently has the algae taken over), more CUC, less light, less food, and additional filtration (mini hob skimmer) to no avail. My corals aren't doing too well because the gha is encroaching on their polyps or skeletons and I feel like giving up. I feel like I'm about to lose my investment to a bunch of algae.
What can I do? Is there a chemical I can use to flush out some of the algae and use manual maintenance to finish off the rest? Something I haven't tried? I'm sure I'm not alone in this, but I wish I could press a restart button and have a clean tank.
Please let me know what I should do.
