Thanks,A couple thoughts:
- Increase your CUC
- I've had success with Vibrant on a mature tank
- If you are still in your 1st year with the tank, this may be part of your maturing process as the nuisance algae sort of get ahold prior to the nicer competitors (coralline etc...)
Hi,An excess of available nutrients, particular the majors like phosphates and nitrates. Keep an eye on possible iron and potassium sources which may also help fuel hair algae. Hair algae spores and fragments are so abundant that keeping it out of the tank via quarantine is unlikely to be successful. Your best bet to preventing this algae from taking hold is to maintain a weekly water change regimen, maintain your filtration and perform manual/natural algae removal as it forms. Proper magnesium and alkalinity levels are thought to discourage the growth of many species of GHA. You want to reduce not increase nutrients.
Green Hair Algae or "GHA" is really a broad term that covers hundreds of species of green simple filamentous algae. These species tend to be simple, fine in texture, and have few distinguishable features. True species level identification requires a microscope. Green hair algae can be pulled out easily, and tooth brushed or scrubbed off the rock work. This is easier to do if the rock is outside of the tank. If it is growing from the sand sift it out with a net.
Once this is done, do add some: Florida Blue Leg hermits, Cerith snails, Chitons, Turbo grazers, Conchs, Emerald Crabs, Pin cushion urchins and a few margarita snails. It is readily accepted by many herbivores, but because it grows quickly it may persist even in a tank with a fair amount of cleaners.
Best reduction would be reducing white light intensity and adding 1.5ml per 10 gal of liquid bacteria during day and 1ml of peroxide during night per 10 gals for about a week. It should starve out the Hair algaeHi,
I have been doing weekly waterchanges, from between 10-15% I stopped while fighting dinos as that was generally recommended.
My alk is currently at 9.3dkh, mag is generally ~1350-1375, cal is a little high now at 480, but im working on dropping that down to 420-450, im using the red sea 3 part to manage these.
There's no additional source of iron/potassium I could think of.
The algae is generally more of a brown algae than a green, but as far as identifying it, is there any benefit to knowing exactly what species of hair algae it is? I assumed that the treatment is generally the same.
I'm in aus, so no blue leg hermits, cerith snails, chitons, emerald crabs or margarita snails to be found here. but the rest I now have.
I'm not worried about getting every last strand, if it grows behind rocks, or the back of the tank i'm fine with that, i just really want it so its not growing over corals.
Yeah i agree, thats why in the title i was saying they are undectable, i know there is nitrate and phos present, its just used up rapidly by the algae.I almost guarantee your nutrients are not zero, gha is consuming your nutrients which is giving you a false reading..
Im only running blue lights as in, have been since i was battling dinos. Which bacteria do you suggest? I was using refresh and waste away to battle dinos, either of those sound good?Best reduction would be reducing white light intensity and adding 1.5ml per 10 gal of liquid bacteria during day and 1ml of peroxide during night per 10 gals for about a week. It should starve out the Hair algae
Are you certain that you are dealing with an algae? Can you send a photo of it under white light?Hi guys,
I have had 0 nitrate/phos for a while now (salifert kits). It lead to a pretty messy Dino outbreak, I'm pretty sure I have now beaten the dinos through a combo of Refresh/waste away, siphoning through a filter sock, running only blue lights and HEAVY feeding. I have a 56G tank, and went from feeding 1 cube daily before dinos, to now feeding 3 times a day.
So I still have 0 nitrate/phos, and my dinos have been replaced by a pretty heavy brown hair algae outbreak. I understand that the reason I'm having 0 nitrate/phos is because the algae is up taking it before it can be measured.
My main question is, should I reduce feeding as the hair algae is consuming excess nutrients, or should I try and dose to increase my nitrate/phos into detectable levels. Ultimately I would like to have ~5ppm nitrate, 0.03 phos.
As far as anecdotal, most of my corals don't seem to mine, 2 of my hammers are splitting, riccordea is spitting out babies, acro is encrusting. Some zoas/leathers are getting annoyed as the algae is growing over them, which I try to remove each night, and a birdsnest is slowly dying as algae grows up it.
And for cuc, I have increased it recently to try and help, ~ 16/18 hermit crabs, 13 turbos, 2 trochus, a few nessys, stomatelas (unsure how much as they were a hitchhiker and seem to be breeding) and I now have a small tomini tang (tang police i know, ive already discussed with several lfs that will do a trade in when it is to big, if I haven't upgraded my tank)
Any help would be appreciated!
Okay sweet, i do get the occasional patch of cyano but that just blows away and hasnt really been an issue beforeIt certainly looks like hair algae and since you are ripping it off, not merely blowing it off with a turkey baster, I would say it’s GHA or at least a filamentous algae and not cyanobacteria.
