BBA issue?

[aquarius]

I understand that hydrogen peroxide is also useful in killing BBA. Anybody who has tried it care to comment on it?

[sunnydaze]

Use a syringe to squirk directly on to the BBA it will oxydise the BBA turnin it to red than to white than eaten by SAE and Yamato. Works every time. I usually uses no more that 15ml/100l. But its better to get to the root cause i.e. CO2. You can get Opthomic grade from optical outlet, brand is AMO Oxysept.

I have quite a large patch of BBA on the gravel and will probably have to squirt it with hydrogen peroxide over a few days and is wondering whether is it possible to use 15ml/100l for each day or for alternate days?

I'm desperate cos i've kept plants with CO2 and have very very bad BBA. Now with low tech tank still the same though i've cleaned the affected areas like wash filter, DW plants etc to start anew but still the same NIGHTMARE.
BTW i just top up water weekly, no water changes.

The ultimatatum is to redo the whole tank again, wash everything down including the substrate and add in new water. Otherwise, you just have to use hydrogen peroxide to kill them. Since it is low tech, it is possible that your plants might not have enough nutrient or lighting to grow and compete effectively against BBA.

Hydrogen peroxide only works against BBA? Or can deal with other algae in general(eg. hair algae, staghorn algae, etc) ?

[sunnydaze]

I have tried up to 3 consecutive days of dosing without any casualty. Btw this is the product i am using. I use Opthomic grade as i believe its does not contains contaminants.

??? that one for contact lense?? I didn't know you can use that one as well

I've sucked out as much BBA from the substrate as possible (abt 90%) during the rescape, wash filter and whatever that needs to be washed, change 80% of the water, change the direction of the outflow tube of the filter a few times (in case it's circulation problem) but to no avail.

Tank/water specs info
Tank : 3ft x 1.5 x 1.5
Kh : NA
Ph : NA
Light : 2 x 39W T5 (10hrs/day)
Fertilization : 1ml of seachem flourish a week
Feed fishes every day
Top-up water every week

The BBA is now getting from bad to worst and i'm at a lost as to what else more do i need to do or have not done to rectify the stupid problem.
Going to give up liao.

I've moved this thread out fro caRoland's orginal post of Why?What?How? (Algae Intruders)

[the_r0ck]

I've used H2O2 for BBA, BGA and hair algae. Works with wonders. I go about 2ml per gallon and squirt it directly on the algae with a syringe.

I use it every alternate days until algae is gone or the tank becomes cloudy (BB failure). If the tank becomes cloudy then better do a WC but it is highly unlikely if you do not go over 2ml/gallon.

That said, it is still a last resort.

Bought myself a bottle of hydrogen peroxide 2 days ago at NTUC phamarcy. Used it as suggested by the bros here and within seconds can see the BBAs bubbling. BBAs turned red today hopefully it'll just come off whatever it's stuck onto this one or two days. Just a note : my fingers accidentally came into contact with the solution and it became ichy. So do be careful when using.

BTW i'm afraid that it'll come back cos i think the root of the problem is still there though i'm not sure what is it??

I've also turned off the surface skimmer to reduce CO2 lost. Hope the experts here can help me analyse what the is problem?

improve your CO2 and water circulation. BBA usually because of this

[aquarius]

My tank is a low tech non CO2 tank. My rain bar which is about 1.5ft long is now attached to the back of the tank and pointing upwards and towards the front/viewer. Creating a very gentle surface movement. Previously i was pointing it downwards at 45degrees, than later pointing it straight towards the viewer. But the BBA continue to spread.

BTW the rainbar is all along half way between the water surface and the gravel. My friend who uses an overhead hang-on filter dosen't have BBA despite having more surface agitation than my tank.

Add a SAE, better the fish than you doing the work.

Hi aquarius and all bros/sis,

I have the same problem as you do. My 2ft tank is attacked by BBA. My 2ft is covered with fissidens tied to wire meshes. How is your progress so far? any improvements?.

I would like to buy the solution too, what do i say when i wanna buy it from phamarcy? and how do i apply it to my tank? because the bba is all over the tank and at the fissidens plants too. will it effect my angels in the tank? since you said that your fingers became itchy upon contact.

Thank you to all.

hi, i notice that after my hair grass convert from emerge to subemerge form. the old emerge hair grass got attack by BBA. do i just leave them there to die of natural death or must i remove every trace of it? attack is only targeted at my hair grass.

[StanChung]

Soulfinder,
You should trim it while having a small, siphon hose next to it.

[kaer2000]

in my case, the hydrogen peroxide seems turn the mosse to white color too. But only on the area where i syringe la. However, good news is the BBA die, and the moss will still come back, Just the moss small leave died, it will still continue to grow

[Plantbrain]

I just trim off the BBA and add more CO2, works everytime.
No need for Excel although that is about the most useful product, H2O2, Bleach dips etc.

Most things will kill moss/liverworts like the algae, so there is a penanlty and the remaining leaves/fronds etc are ratty looking, they grow fast with goodcare so focus on horticulture, not kill algae.

You did not get into this hobby to learn how to kill algae, remember?

You got in to learn how to grow moss.plants etc, so focus there. Algae is just a symptom of poor conditions provided by you to the plants, so it's your fault, not the algae's.

It means there is a lot more room to improve the horticultural skills and thus the plant's health by addressing that, rather than wasting time killing algae and trying to out wit it.

H2O2, and most algae killers do not grow plants. Which is why they never help other than a short term thing and leave a ratty leaf behind. Just trim it and fix the root cause, the plants will grow back fast if so.
