    Phosphate reactor should work.

    Else try an algae scrubber (ATS). Basically you provide the algae with a better place to grow, that will out compete the algae in the tank for nutrients, and you can also export the algae and whatever it consumed easier.

    I have tried everything eventualy see results hope it works Phoshate remover worked for me plus lights only 3 hours on a day start to die off scrubber is okay but make sure it is closed that insects cant get in else you will load your nitrates and fuels it better

    Tell us about your system, size, skimmer, flow, amount of live rock, how long has the system run, what water you use to top up and or do water changes, what fish and how many, corals, amount of live rock, what lights and times they on. Then we can help you. Find the cause and resolve that and you will not have algae problems. How many clean up crew you have ie. turbo snails, hermit crabs etc. :whistling:

    Hi G-Man - where are the green hair algae? Can you please post a picture of the algae? Also - try an up-close pic for us?

    Also post your water parameters - including the following:
    - nitrates
    - phosphates
    - pH
    - alkalinity
    - magnesium

    Deadmeat - it depends on the actual nuisance macro algae - but if you increase your magnesium, and IF you are suffering from derbesia or bryopsis - then this is one of the cures of these nuisance macro algae types.

    hi guys thanks for the replies!!!
    i'll get some pictures up soon!
    i have a 400litre + tank with about 30kg of kenya live rock
    4 t5 lights (3 white and 1 blue)
    a reeftek skimmer with 2 thermostats and a new chiller

    i tested the water the other day with a Sera test kit (its one of those kits that has just about every test in it) and everything was ok according to their guidelines except the nitrates. my calcium was also a little low.

    every weekend i add magnisium and calcium powder to the water with some tripple buffer. i ve been doing this for a while now. my tank has some soft corals and hards one. umfortunately i dont knoe their names, they looked nice and theguys at the pet shop are good salesman.

    i also bough way to many fish at once and they all died (white spot) so now i only have 2 6 line wrasses and 2 damsels. i also have 2 shrimp and a huge turbo snail. there are also plenty little snails that i think came with the live rock. 2 orange star fish and ive also see a huge black slug. 3 tube worms

    is there anything else you need to know?

    G-Man, have a look here, it will give you a basic idea:

    here are some i use

    Live rock.....................at least 1kg per 7.5 liters

    Sand...........................4.5kg per .5m2 of tank bottom =25mm deep

    snails..........................1 per every 5 - 7 liters

    hermits.......................1 per every 9 - 18 liters

    fish.............................initially............ 25mm per 18 liters

    eventual max...75mm per 18 liters

    water movement..........20+ times the tank's capacity per hour (ideally)

    lighting........................for corals...4 watts per 4 liters

    btw, what role does the snails play in the tank? thought they are more of a nuisance.

    snails/hermit scrub the rocks clean as fresh algae/diatoms start to grow.

    Jeez, Sean....by those calcs I'm gonna need 371 snails and 146 hermits...

    ok guys ive added carbon in filter bags to my sump, bought a phosphate reactor and only turning on the lights for a few hours a day (split up in the morning, afternoon and night) i have done 2 water changes in the last month and this algae seems to be loving it and is growing more and more!!! ive been adding a little extra mg than usual.

    WHAT DO I DO? i dont have a marine tank anymore, just an algae farm

    how long you been running the phospate reactor?
    did you test your water parameters lately?
    what salt you using?
