    I'm not sure what caused this bloom but it's been bad. ND3_7172.jpg I put one of the 67000k florescent flood bulbs in my fuge about a month ago and cut back my chaeto to about half of what it was. ND3_7293.jpg Also, my DI unit exhausted at the same time. I had to add top off water of regular tap for a few days. My corals started to close up and look unhappy so I moved them to the tank upstairs. The new 5 stage RO/DI unit came about a week later. Right about that time I noticed all my snails were dead and the back of the aquarium was covered with brown algae. Thats when the red algea started. ND3_7214.jpg This tank has been in direct sunlight at sunrise and an hour or so after that every day. I considered maybe the morning light was causing the red algae so i installed blinds. The brown algae went away a few days after the new RO/DI unit was hooked up but the red algae, or at least that's what i think it is, will not go away. I think my fuge is in bad shape too because the red algae is growing on the chaeto and seems to be smothering it. ND3_7296.jpg I put a small power head in the fuge but it looked like the chaeto was dieing because it started turning white so i took it out. I've tried turning the flow up for a few days then down for a few days but nothing seems to be doing anything. The chaeto is getting smaller every time i look at it. All the mushrooms i left in the tank shriveled, released their stringy insides and started breaking apart. I think they are dead. The fish are doing really well, I still have several crabs and all of my coral shrimp are still alive. I have a Aqua UV 15W Advantage 2000+ HOB UV Sterilizer coming in a few days and new bulbs for my hood. My parameters are nitrates 20, phosphates 0, ammonia 0, Calcium 450, ph 8.3 salinity is dead on, water temp is 79 with a JBJ chiller keeping it consistent. I'm also using these in the tank
    SEACHEM PURIGEN
    SEACHEM PHOSGUARD

    I don't understand why this is happening after having the tank for several months with no problems and very healthy coral. My skimmer is working very well giving me about 2 cups of thick green skimate each week. Maybe there is just to much organic matter in the water. The surface has a film on it I can't seem to get rid of. ND3_7235.jpg

    Can you guys throw me a bone here. I'm doing everything i can and nothing seems to be helping.

    Hi Nikon

    The red algae cyno - I have no experience of this problem so cant offer any valuable advice - there is some information on Cyno on the sticky threads at the top of the forum
    hopefully someone else can also offer advice

    the film on top of the water - its protien build up and the protiens just like they do in a skimmer lock to the surface of the water , surface tension
    you can see the area being kept clear by the water outlet - so to remove this problem all you have to do is increase the amout of water movement at the top of the tank, this puts the protiens back into the water column where eventually your skimmer can get at them

    I use newspaper to get rid of the surface protein! Works a treat :)

    i am fighting the same thing rite now they say marclyn or whatever it is works its the medicine for fish ick i think, i havent tried it yet as i was waiting for it to be a last resort since it also kills some beneficial bacteria . i hate adding chemicals but if its gotta go its gotta go and maybe you've reached that point

    Hey Nikon, as far as the protein on top of the water, that is because there isn't any circulation there (a dead spot) you need to aim one of your power heads toward the top some to get some surface agitation. You don't want the water to be churning out of the tank but you do want to see the water churning. Then you will also get a more of the glitter look we all love. As far as that algae, see if you can scrape it off, if it is slimy it is cyano but my guess is it is Coraline and will be hard and not scraped off easily. You want that so don't worry about it.

    I had Cyano problems and got some cheato and got my nitrates and phosphates under control and got rid of it. You could also use Chemi-Clean it will take it out but not many folks like usin chemicals....
