3 days of no light is not enough to starve hair algae.--- so not at all?
1. cut back feeding--- I will and have
2. Feed quality foods, rinse frozen foods --- I do. And the rinsing is debatable. But since I have issues I may until it goes away.
3. Use RO/DI water only. Change your filters every 3 months, and regularly test TDS for ZERO. --- I do and they are
4. Use additional flow in that area of the tank. ---- not necessary, flow is not an issue.
5. gravel vac your sandbed --- this is something I need to start.
6. blow your rocks off with a powerhead before water changes. --- I do this every day
7. Manually remove the hair algae and invest in a small clean up crew to keep it in check. --- what will eat it because I have mexican turbo nassaurius and they don't eat it.
8. Take the affected rock out and use a spray bottle with hydrogen peroxide in it... spray the algae thoroughly and then put it back in the tank. let sit 1 minute. ---- not too sure about this
9. Reduce your photo period between 8 to 10 hours per day. --- I will need to adjust
10. Replace your lights if they are old bulbs. --- I have led
11. Double the light watts that you have on your refugium, and set the refugium timer for 16 hours on, 8 hours off. Replace refugium bulbs every 3 months. --- need to adjust. This could be the main issue because I only have pc now
12. Water changes to reduce overall nitrate and phosphate and replace elements. --- 20% every week. Never missed. Thinking about doing a 50%?
13. Use a properly built and maintained underwater algae scrubber in your fuge. Don't think I have enough room
14. Use GFO In a reactor. Replace your media at regular intervals.
---- I have some phosaban that I never used not sure about it
Just checked my phos -.03 and trates at 2.5
