    I have a problem with my tank. Please help!!!

    Ok, I had my water tested tonight to confirm my readings. 420 calcium, 0 phosphates and 80 ppm nitrate. :b13:
    I am having a cyano outbreak that I am battling and losing. Now I have done the usual, changed the flow to directly on it. Now reading up on it more, my lighting could be causing, my tap water (not using ro water yet) and maybe my feeding habits.
    Lighting is coralife 48" lunar about 10 months old. Now my actnic are probably shot and should be changed. Would this cause this problem?
    RO water yes could be but never had a problem before.
    Feeding habits haven't changed. Feed cyclopeeze, spinula brine shrimp and algae flakes. Never really had a problem with cyano or nitrate before. Fish and corals eat everything within 5 mins. Oh, one time a day
    If anybody in the orleans area have a RO unit that they could spare some water (5 gals a week for the next month) would be really helpful. Or I might have to go buy distilled at shoppers.
    Any suggestions would be great. Thanx in advance.

    Its more than likely your feeding... the end of the line is nitrates... you should get your ammonia tested aswell. I would do a good %30 water change to get your nitrates down(with RO water) and then run some phospahte remover(even though your reading 0... its likely the cyano is feeding off it). lower your feedings... even though everything is eating it... the food is still going out the other end causing more waste to enter your tank.

    I was starting to get cyno in my all aquarium but 2 days after running some phosphate remover(I used cut-to-size pads) and its all gone. HTH

    Make also sure your skimmer is working well.

    I will cut down my feeding a bit. I will try a phosphate remover too.

    My ammonia is at 0 ppm

    Can you change water with distilled water

    My protein skimmer is running perfectly. Producing nice skimmate.

    What about a hang on refugium? I had one on my old 45g. I swear by it!! Cheap too.

    yeah adding some macro algae helped a lot for me too... but if you already have cyano, you could syphon it out first.. that helped a lot.

    I didn't see how old the tank was??
    depending on the size of the tang that probaly doesn't help. tangs are frowned upon in a tank that small.
    no need IMO for the cyclop eeze either. just adds to the pollution. your soft corals will get enough ''food'' just from the fish.

    distilled water will also work.
    make new batches of change water and do 20-30% a few times over the course of the coming weeks. slow down on the feeding, clean that skimmer ( if any ) consider getting a bigger one. build a refugium, water changes will help but wont fix the problem.

    I do not think your lighting could cauz this. its a good thing to swap the bulbs, but shouldn't create troubles like this unless something else was at fault. Powering them off may fix temporarily the trouble but is not the root cause.

    post pics of your current setup if you can. we might see something ovious.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    I will try to get some picks tomorrow. Have to work today and tonight so it is going to be a busy day.

    As for the lighting, I have read that the bulbs getting old change their spectrum which could cause the problem.

    Neat thing my girlfriend found out about cyanobacteria last night in one of her microbologie books (french). Cyanobacteria will feed off of glucose and sugar. I have been small dose of sugar for the past couple of weeks which the outbreak has got worse since then. They take the sugar, phosphates etc and actually produce nitrogen. These two combos are probably causing my outbreak and high nitrate levels. Were never this high before.

    The tank is 10 months old now and I cut my lighting down to 4 hours a day as of last night to combat this problem. I will try siphoning out the cyano this weekend.

    I will have to look up a hang on refuge on here for a diy project.

    Thanks again guys.

    Why are you dosing sugar? Are you trying to sugar coat the fish?

    Lighting shifts can cause some algae blooms as you suggest but this is only a minor factor at this point.

    This is what I would do
    1. Keep the sugar for your ceral, no more for the fish.
    2. Post the tang for sale. 55g is too small and they add a large bioload.
    3. Siphon out the cyano as much as you can.
    4. Set the skimmer to run wet so the skimmate is a little thinner
    5. Cut back on the food, the fish won't starve.
    6. Reduce the photoperiod, this just slows the growth doesn't fix the source.
    7. Do a large water change using RO/DI water. Stop using tap water.
    8. Add a refugium with cheato to help draw out the nutrients.

    Good luck.
