GHA leave me alone!

awhile back i had 2 fish die on me within a week like 5 months ago, both had died early in the day and by the time i got home they were pretty much consumed by my cuc leaving little chunks all over, after that i had some high nitrates and phosphates, with combination of this and using an old bulb on my MH unit GHA had grown and spread all over. i also changed out my fuge substrate from crush coral to aragonite because i suspected that to be a source.


i have battled down all possible nitrate sources, and now my nitrates have been untracable for 2 months, i pull a handful of chaeto out a week, 10% wc each week on the dot with RODI, have been very carefull with feeding, and have a brand new MH bulb, yet this GHA presists... i am 100% sure there is no more cause in my tank for high nitrates or phosphates. i just cant get this stuff to starve out.

i siphon what i can each week when i do a water change, but it doesnt seem to help. i noticed it only really grows on certain rocks if that helps..


any suggestions?

 

I'm having the same problem!! No matter what I do it won't die and just keeps getting worse. I FEEL your pain!

I'm hitching along for the ride.

 

flow?

 

hitch right along! hopefully we can figure this out.

 

a k2, k1, a nano and a rio 2100 RP from my sump in a 37g, the GHA is flapping around in current. i have thriving sps for gosh sakes.

 

Same!! Everyone tells me GHA doesn't like high flow, but my GHA LOVES it! It is growing off the ends of the power heads!!

 

Are you guys sure you don't have bryopsis rather than a generic GHA?

 

Could you explain the difference and how we tell?

 

Bryopsis: A Common Pest in Aquaria: An unsightly, green alga that herbivores dislike to eat.

After reading that, it may be what I have! It's impossible to pull off the rocks, and no one will eat it. But I'm not sure.

I have a pincushion urchin coming tomorrow. I hope he eats it!

 

Arm your tank to the teeth with turbo snails lol.it doesn't sound like they will run out of food anytime soon.
