I know that this has been covered in the past, but im after some fresh ideas since everything i try seems to fail.

Tank is an IM20 (20 Gallon/90 litre)

Just tested and got the following:

Nitrate = 0
Phosphate = 0 (Salifert kit so take this with a pinch of salt)
KH = 8.9
PH = 8.2
Sg = 1.026

I do a weekly 20% water change on a Tuesday evening.  These tests were performed BEFORE that

Im currently running an AI Prime HD light.  Lighting has been cut down to around 6hours a day

I dose 2g of Seachem Reef Builder twice a week

I run a mix of 65ml of seachem matrix and 45ml of seachem phosguard in a little reactor with coarse foam sandwiching them in stopping them from tumbling.

I did a 48hr blackout earlier this week which didnt seem to make any difference

Im now at a loss.  Please somebody give me some suggestions on how to get rid of this stuff.....

Hi
Have you got a pic of the offending algae?
How much are you feeding and what are you feeding?
What fish have you got?

What have you tried?

As a last resort, Fluconazole works but takes a while with GHA. Vibrant also works but is expensive AAC and Charterhouse sell it.

I give about half a cube of frozen mysis a day.  Only a pair of clowns and a pair of bangaii cardinals in there at the moment.    Will get a pic when I get back

Even though your phos and nitrate are zero there not, they are being used up by the algae so don't register.
You either have to get something that eats it, out competes it or remove the nutrients before the algae can use it.
I think the the first is out for the likes of blennies or tangs but what cuc do you have?
The second is either a fuge or algae scrubber wich I think your tank might be to small but you could buy some nice macro algae to go in the display? They grow slow and are easy to harvest wich would out compete.
Third is by means of bacteria driven system so bio pellets in a reactor or carbon dosing. But you would need to run phosphate media with that.

I found rinsing my frozen food has helped with phosphate, I get some tank water in a jug , put the cubes in a small pot with some tank water and let the cubes defrost then drain the water of through a copepod sieve then put the frozen in the jug and pour in the tank.

If any of that takes your fancy we can talk more about that point

Good advice above.

Also reducing lighting, or do a blackout to kill it off, then do huge water changes to get rid of the nitrate and phosphate that get released as it dies.

Might also be worth getting your results checked at the LFS, as sometimes you can have a duff kit, or it may be out of date, etc.

Third is by means of bacteria driven system so bio pellets in a reactor or carbon dosing. But you would need to run phosphate media with that.
...and a skimmer to take out the bacteria strings it creates, and oxygenate the water.  Before doing this, read up, as you need to be careful or you will create a bacterial blood and suffocate everything.  It def work though, and a lot of people do it successfully.

If the GHA is long enough to get hold of simply pulling it out can help , as this stops it releasing nitrate and phosphate as it dies off , which in turn saves media's .

Hi how did you get on? I've tried everything you did too. The 48 hour blackout worked temporarily but as soon as I turned the lights back on the water suddenly filled with hundreds of strands of algae. Even the dozen snails I employed to munch it now have hair algae growing on their backs. Looking to get a foxface or unicorn tang, but worried they will get too big for a 240 litre. Any suggestions on fish ?

Hi mate I'm wondering how you got on with getting rid of your hair algae? It's a nightmare that stuff, it caused me to give up on my first saltwater tank as I couldn't get rid of it and then I made all sorts of mistakes and killed everything, I haven't had my algae spike yet but just trying to be prepared for it this time

Mollies love it, if you have the patience to acclimatise to saltwater? Or see if anyone has any Sailfin Mollies that are already reef acclimatised

Wow I wouldn't have thought a molly would do that, I have kept them in freshwater before but didn't realise they could also go in saltwater, I'd imagine it'll take a few weeks/months to acclimatise them, I haven't got any algae at all just now but I do want to be prepared this time, the first time I thought it looked nice and actually watched it grow feeling happy that there was life in my tank lol never will I do that again

I used to start my cycle with a Molly back in the day, instead of a Clownfish
Can do the same with Guppies as well. They eat it but not as much as the Mollies. Be aware though Sailfins grow much larger in Saltwater than Fresh! I've seen a really amazing Caribbean themed reef with Mollies and Guppies. Looked amazing with Guppies, Hermit Crabs Corals and Mangroves
