Ok here is the deal I have a 54 gal bow corner setup. The tank has been great for about 2 years now no problems. The about 1 month ago i took out the last of the bio balls. Everything was still kick *** no problems I was running 1 65watt actiniic and a 10k pc which where on its way out so boom I get the red algae all over covers eveything couldnt get rid of it then I buy the red slime remover and within 2 days it was all gone.. So now i go out and pick up a nice pc/mh setup with (2) 65 watt actinic and 1 10k m/h everything was great fish all doing great all my mushrooms and inverts where great within about 2 weeks of adding the lights I got this brown algae thats very dark and hairy everywhere. I do numerous water changes but nothing it wouldnt go away it got so bad my anenome dies and takes my tank out killing 2 percs,1 flame and 1 mandarin and 1 scopas tang I was away when it died and didnt get it out till it was to late . So only thing left in my tank is a cleaner shrimp and probrably 10 snails some hermit crabs and about 70lbs of live rock. No for the past 3 weeks i have been tring to get this algae stuff out to no avail. I went out and bought an r/o unit everything i can do. Its a very stringy algae that covers the substarte after about an hour and covers everything reaqlly fast my water is a murky brown color I just dont know what to do.. My nitrates,nitrie, are 0ppm my amonnia is at about 5ppm and the phosphates are at next to nothing. My skimmer pulles so much crap everyday i must get a gallon of this smelly brown mud every 3 days I have no clue how to get rid of this and its really discureging As I have so much wrapped into this can someone please help figure what this is and how to elimiate it I have pics if i could figure out how to get them up
