BBA on hairgrass

[emmanuelwoon]

I'd read that to clear BBA, the solution is to rub them away. but is there any other solution to clear them away ? i think it is not so easy to scrub my hairgrass without uprooting them in any way.

any other way to help my hairgrass ?

thanks.

Trim them away, you can trim them till 1cm.

trim is the best for hair grass, but if it has not spread, you can use excell or H2O2. Use syringe and inject it close to BBA. You might need to do it couple of days

agree with shadow, i have my fair share of bba on hairgrass, use excel or h2o2 [buy from guardian 7.50 per 300ml], but daily use of excel does keep most algae at bay.

not for the green hair algae that i'm currently fighting a losing battle with
keeps coming back all the time.
there's also some BBA on my Japanese hairgrass and the method i'm using is trimming them often to get rid of the BBA, seems to be working

For green hair algae, if your tank is small, do black out and starve yamato shrimp
I had 20 cm tank before with hair algae issue, I just use empty A4 paper box from office to cover it up for 3~4 days.

By the way, you still need to fix your water condition, otherwise it will keep coming back.

H2O2 works for green hair algae too.

oh ok, i'll try with excel first. if not i'll go for a trimming session.

doesn't SAE help with BBA btw ?

Trimming is the best for hairgrass. For SAE when are small they are hard working and when they reach about 1.5" onwards or adult they are very lazy, got to retire them, if you have moss, they will nip at them till left stem only.

actually in fact, BBA is caused by poor circulation of CO2 ?

if thats the case, will an improved circulation kills of BBA ?

i should have heeded ur advice adrian. now i install back my rainbar liao. guess i'm too late. haiz.
but as you said, trimming is best. but how long does it takes for it to grow long again ? if i come home see botak hair grass, definitely very low morale.

Hairgrass grow pretty fast with right environment. Algae is just part of ecosystem, not to be afraid of, some adjustment would stop them in time.

If you are using CO2, make sure it is not limited. More movement on the water surface for O2. Also yamato shrimps do help to reduce them.

[emmanuelwoon]

But i can't have shrimp, they'll be eaten up by my discus.
I'm trying to have more circulation right now.

I find BBA is caused more by excess of Phosphate, rather than poor Co2 circulation.

I am having some BBA (in fact quite an irritating amount) in my 4 feet tank. Co2 is fully cranked, and circulation is 2x 2028.

Why I suspect Phosphate? because I've been seriously overdozing phosphate. So when the plants took up the nitrate and the micros, left with phosphate.

And I've also read on the web it's phosphate, rather than inconsistent Co2.

Anyone with same experience?

Cheers, Christophe

I've recently gotten BBA and GBA attack for my 2ft. I suppose trimming will help. I got rid of it once before using excel...but I can't do that now as a my Valisineria is sensitive to excel and will cause it to melt. Possibly due to lack of dosage on NO3? I've recently run out of NPK...or it might be because I've not cleaned my reactor for a while...

Care to post the link? interesting finding you have there.

The more I think of the water parameters in my tank, the closer the conclusion is that Phosphate level is the culprit. I have been dosing a lot og KH2PO4 recently.

[emmanuelwoon]

If low level of phosphate will cause spot algae. but please don't quote me for saying that. Read somewhere before that there is a relation between low level of phosphate and green spot algae.

Then, perhaps it seems contradicting as i've got both spot algae on the glass wall and also BBA.

maybe something for us to think about again. maybe spot algae isn't cause by low level of phosphate ?

[emmanuelwoon]

wow, interesting site.

maybe i should try to dose more nitrate.
learn something new again

what if you have high nitrate level, which will cause the green spot algage (and very strong light)..... and after your plants took the nitrate, then your phosphate level is high (due to overdosing).. so may have bba.

now working hard to get the right balance again.
