Listen if your having algae problems, first off it ( any algae ) needs a few things to over run your tank. 1, over feeding , ( causing nitrates/phosphate etc. to build. ) 2, the Bryposis or other i.e hair algae "what ever" will feed upon this, and it will spread like wild fire. 3, to long a "photo period" will just make things worse , it needs light to grow to. ( NO longer than 7/8 hour lighting time. ) 4, also "wet skimming works well" if you skimmer is adjustible, works great in helping remove algae spores, light water materials, etc. ( this should be done while your home, it will fill jug/bucket quickly some times ). You might consider turning lights off all together for a few days/week if you can, or you can remove each rock, scrub hard and swish in some ro water , place the rock back in tank. and/or cut lighting down to nill' ( somthing like 2/3 hours a day if you have some corals,) Corals can surrive with minimal/no lighting for quite some time. Lighting: change out bulbs that are old , ( any buld thats older than 12 months, some people change them out sooner than that ), spectrum changes over the life of the bulb/s and some spectrums just encourage algea growth. Trick is to get a handle on it ' before that crap hell spawn over runs the tank, even the best of us have had to go thrue what you have now.
