Is this Cyno or...????

Ok i have battled with this for some time and i am getting more and more frustrated when i see my sand bed get crap all over it within hours after a water change.

I have to clean rock once a week this cant be right
paramaters are:
amm:0
nitrite: 0
nitrate:15 (dosnt get above this most of the time is 0)
KH: 10-11
Cal: 375 and still rising

Filtration, there isnt much, its only a skimmer with stacks of LR, but i dont have that much of a bioload at all.
the tank is 75gal.
Always use ro/di for top ups and water changes.
this exploded when i got my halides over a month ago.

I cant think of anything else you might need????

any help is appreciated.
 
Check phosphates - in my experience they can be one of the leading causes of cyano blooms. Use rowaphos to bring that down. To combat the cyano directly, look into tongan fighting conch - put in one per 5 gallons, they do a great job.
 
getting a tongan fighting conch in Aus, next to impossable.

I will try another phostphate sponge or too. I did try one and this didnt do all that much.
I really dont know how this can been be phospahtes, as i said i use ro/di and i feed every other day (not all that much the food is all gone within 30 secs)

But hey i will give anything a go at this stage.

I will keep you updated.
 
Run Triple distilled smirnov vodka for 3-4 weeks and your cyano will subside.

I am guessing your tank is not that old.

Make sure your skimmer is substantial enough for your system also.

1ml of vodka per 100 litres per day, (Half in morning, half at night).

That is: 1.5 mls morning, 1.5 mls night. (Your tank is 300 litres)


DONT ADD MORE THAN THIS, ONLY WHAT I HAVE STATED.

Your cyano will disappear. Slow down on the feeding for a couple of weeks also.

I 90% guarantee results.

Trust me on this one....
 
What you have looks to me like brown diatoms. If you look it up on the net you will find that they are common in unestablished tanks. You can just wait it out and they will eventually subside.
If you are impatient like me and everybody else buy as many cerith snails as you can afford and they will help.
 
i'm going through the same thing right now, similar conditions as you. i just upgraded to MH about a month ago also. they are diatom algae and the increase in lighting is most likely what caused them. just be patient. they will eventialy go away.
 
yessssss thats better then the cyno, its confirmed others had also said Diatoms.

is there any sort of ETA on this stuff?
or is it a just wait and it will go one day?
 
They look like Dinoflagellates to me. Notice the bubbles in the second picture. Will not just go away. Siphon off the rocks as you do water changes. increase calcium, this should help your skimmer produce more skimate. You didn't mention the type of skimmer you have, is it sized for your tank? What are the TDS readings of your RO? What kind of flow do you have in your tank?Do you have a clean up crew?
 
I would have to disagree about it being Diatoms. Diatoms do not have air bubbles attached.

This is Cyanobacteria and is controllable.

The Vodka will not harm anything in your reef so long as you stick to the dosage.

Most tanks will go through at some stage prior to maturity.

It is a stage of development that can be sped up and controlled with extra carbon sources for bacteria, (Vodka).


Good luck.
 
bubbles in algea cover surface has nothing to do with algea species as its a natural result in new tanks as the surface is newly place underwater and is highly oxygenated. ver very commen in new tanks. even diatoms can get air bubbles stuck under it when a tank is less than a few months old as its proccessing ....very common and not an issue. i believe its not cycno but diatoms. cyno is ussually redder in my experince. in either way it is common in new tanks (cyno and diatoms)but also your water source appears to be suspected of high phos. what do you use...tap? ro? distilled?
 
could be cyno but bubbles have nothing to do with id. new tanks release bubbles from substrate as a sign of establishing bacteria.
google nitrogen bubbles appearing in new tank substrate. very common. solution 4 bloom .....check water source for phos. also reduce adding stock for a few months to eliminate bloom and feed less. food can contain phos and over feeding will add it to chemstry of tank. also excess bioload verses bacteria load does the same. common begining or wanting too much too soon mistake. just some possible cause to consider but may not be your issue. best of luck
 
It looks like Dinoflagellates to me. Very serious problem and hard to over come. Do search on this, you will find the most common solution seems to be raise of Ph.
 
definently stabalize your tank . salinity must not shift , temp,ph,ect. this will help lots of things from occuring
 
If you are still uncertain as to whether this is cyanobacteria or diatoms and you have access to a microscope, stick a bit on a slide and take at look at x400 magnification. Then compare what you see with Google images of these creatures. They are very different, and both quite pretty. Cheers, Des

that certainly would clear up all uncertainty and id it.
 
unfortunatly i dont have any microscop, nor am i ale to get near one.

the algae is not like a dust its more of a sticky sort of algea. hard to explin really. The dark spots have more of a hair algea attached to it as well.

I am going to add some phosphate removers and see how that goes.

RO/DI i dont know what the levels are, i need to borrow a TDI to measure but the filters are only 3 months old, only using the ro unit for the tank. The tank is 75 gal
Skimmer is a remora C, using a larger PH then recommened.

I have 2 3600LPH and 1200LPH ph, this is over 30 + turn over per hour.
so flow should be more then adiqute.

feed every other day.

I did cut the lighting period about 3 hours, but then this did nothing really.

I am skeptical about the vodka idea, ki just havent really heard it before is there anyone else here that has used this method? Not that i dont belive it just sounds crazy.
And also i dont wanna put my investment at any more risk. I will try the phosphate reomvers in the main and see how this goes for a week, if this donst start subsiding maybe its worth while trying this vodka idea.

any other suggestions are always welcome.
 
If you're in the UK, I'd be happy to help ID your troublesome stuff. Just dry a bit out at room temperature over-night and stick it in the post to me. If you're elsewhere in the world maybe there is a reefer in your country that has a microscope and could do the same for you? I think you need to be able to make a positive ID of what you have before developing a recipe for it's demise. Cheers, Des
