gha really?

I feel you man, I havd been living the same green hair nightmare. I tried all that stuff and my water is perfect but still I have hair. You and I have both been posting about this for a while. I just bought a sea hare and he is a maniac. Mowing it down nice. I didnt want to do the magnesium treatment. I have however recently started to rinse my frozen food and I have noticed that I am not growing new hair and skimming .

 

Not laughing at your problem, but you've succumbed to scrubber use. Welcome to the dark side.

 

It would be a good idea - and it wouldn't hurt by any means. It can only help.

 

Have you blown your rocks off with a powerhead about once a month? What do you have for detritus control? Do you have a refugium at all? How well stocked are you? ... You know the drill. lol

 

I am convinced that many larger tanks have flow issues. I'm seeing barebottom tanks more common in large aquariums these days because the ease of maintenance and the ability to better control nitrate and phosphates, not to mention that you can use a lot more flow in them.

 

Anyways... I'll try to help you, but you got over 21 years of experience on me. lol

Get back to the basics dude...

 

High flow rates

Hardcore protein skimming

Algae scrubbing

Refugiums with deep sand beds and macroalgaes

Feed less

Change bulbs on lights

decrease photoperiods

control detritus build up

water changes

check your RO Unit's TDS and change the carbon filter out every 3 months.

decrease your bioload

gravel vac/maintain sandbed

add critters to eat it

 

... etc. etc.

Dose vodka. 

Waite....... don't you have tangs? Get some Zebra snails. Had an outbreak in the bio cube and within 3 days........ clear

I would stick with the Zebra's. Or you can go and get spongebob to mow for ya. bwahahbwahahbwahaha

 

Critters would be my last resort tbh. 

I would not buy anything else if I bought a sea hare, it is going to mow it down, and starve soon after, so adding something that will take away food is not necessary. Secondly, IMHO I personally feel that you can never completely get rid of this stuff, it lays dormant when nutrients are controlled and when they return so does it. I have been battling little patches of it for almost a year now, it's a process it. 

 

I suggest, pulling the rocks its on and putting them in a bucket with no light and letting it die off. It will consume all the nutrients and slowly die off. Then I would put them in some type of QT with light for a while and see if it returns. It basically QT all over again. 

 

This is a hail mary method and has a 50/50 chance of working, as there are probably GHA spores in the other rocks and once the GHA is remove they will probably thrive. I say its work a shot as if you have the space to do it, because if you buy a sea hare and it dies in your tank, its poisonous.

XCali gave some good tips......Though a bad note, the lights out deal really doesn't go far enough.....The nutrients are deep within the rock and need to be stripped......Your only probably action would be pulling the rock from the tank.....The corals would survive without the rock......

Woohoo!!!!

I agree with acrylic on this one. You have had some of your rock so long that it's been storing phosphates all this time. Now that the rocks are spent, they are leaching phosphate. Cure your live rock and get rid of the phosphate. 

Agree with most of what's listed, but if he isolates certain areas we can eliminate things off this list.....He stated doesn't feed much, but doesn't state if he has stuff decaying in the tank.......The GHA is more a Phos issue.....The Phos gets locked inside the LR.....Regardless of decreasing lights, you'll slow it down a tad, but the Phos will continue to leach from the rock.....

 

 

Not really spent......but your correct.....Think of LR as kind of your face with tons of pores.....When those pores clog what happens.....Your face/skin doesn't breathe.....That's exactly what's happening the LR is functioning doing its job.  It's clogged, and it is leaching out the bad stuff.  There are a couple noteable ways to deal with this.....1 being the bleach/acid bath, and the other is using Lanthanum Chloride or this.......which can be dosed to the tank, but you'll need to read before and know what's going on before you do it.....

 

SeaKlear Phosphate Remover......You can find it on ebay.....
