What causes Cynobacter?

[samuelgoh]

Hi dear bros/sis of AQ, anyone know what causes Cynobacter? I been getting them on and off and its really getting on my nerve...

[samuelgoh]

anyone knows about this ?

cynobacter and BBA is giving me headaches..

[Sorab]

The usual suspects for BGA are low nitrates, poor circulation, too few water changes. Blackout is very effective 3/4 days complete darkness.

any feeding during the blackout period ?

[celticfish]

Feeding is not required during the blackout as it is only for a few days.
Abyways it will be too troublesome ans defeat the purpose of a blackout.

Bottoming out of KNO3 and poor water circulation is also known to cause BGA.
IMHO poor O2 too.

[samuelgoh]

i don't think KNO3 is the cause as i am going EI.

right now i can only point down to poor water circulation and/or CO2...

i am using a eheim 2217 but still i find that it is kinda weak in terms of the flow...

[|squee|]

Clean out your filter and pipes, suck up as much of BGA as you can, increase your KNO3 dosage and CO2 slightly. If it doesn't work, do the blackout.

this cynobacter plus BBA combo is really a tough battle to fight!

i had clean my filter and pipes thoroughly!
added an internal filter for better circulation.
replaced my internal co2 reactor with a co2 diffusor instead.
right now, can see that the co2 bubbles are obvious and being push around the tank.
increase my KNO3 from 1/2 tsp to 1 tsp 3 times a week!

going to observe for a while and see how the thing unfolds.
at the same time going to try to get hydrogen peroxide and erythromycin to fight the war with better "equipments"! haha

BGA / BBA here I come!

(i think circulation and dirty filter which in turns means less filtration power are the main culprits here!)

You can also do 50% water change for 3 to 4 consecutive days.
With the other measure you have this should help too.

thanks man , will do just that! =)

Hi Samuel, sorry to hear your frustration. I don't understand, doing EI also get BGA? Is your tank fully planted? Please show us a pic.
Try reducing the photoperiod to 4 hours if you don't want to do the blackout. You can even do that after the blackout for a couple of weeks to make sure it doesn't come back. Some aeration at PPO[photoperiod off] is also good for your tank's BB.

Samuel, how big is your tank? Dimensions.
What your lighting like? W? Photoperiod etc.
Dosing schedule?

[samuelgoh]

The BGA is mostly caused by the failure of my 2217 previously.
there was a drop in flowrate, a drastic drop, and circulation was stagnant in the tank i would say, therefore debris got stuck to the plants and gravel and somehow the BGA starts from there...
the poor circulation in the tank also contribute to the bloom of BGA.

I havent got a pic yet but i would say it is fairly densed.

I am using a 3x1.5x1.5 tank therefore capacity is around 191.14L.
2 x 55w PL is employed for the setup, giving it 2.6 WPG (UK), switched on for 8 hours.

Dosing based on EI's recommended dosage for 40-60 Gallon Aquariums.

+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 1/8 (10ml) Ferka Aquatilizer (Trace Elements) 3x a week
5 ml Ferka K
5 ml Seacheam Iron
50% weekly water change

CO2 at 2-3bps

To tackle the CO2 problem
- I had changed the internal reactor to a diffusor, to improve CO2 efficiency.
To improve filter capability and circulation in the tank
- Had cleaned the 2217, airflow increased.
- Added an internal filter with 200l/h output to improve circulation (going to changed to a 500m/l one)
To fight cynobacter
- tried dosing 250gm of Amoxycillin (similar to Erythromycin), gonna observe for 3-4 days, if failed will try interpet no.9 or sera baktupur.

Let me know what i missed out besides the pictures.

hi,

just to share. I've a 2ft tank, and it was infested with green spot algae, green hair algae and BGA. After some searching online, I found Barr recommending that higher light intensity does not really mean better plant growth. In fact, the higher the light intensity, the more troublesome it is to maintain the tank, since algae are light-hungry stuff. So, I simply switched off one of by 2X36w PL lights, effectively cutting down light intensity by half. Also, I trimmed away almost all of the leaves with algae on them. Now, after 3 weeks, I haven't seen any BGA or hair algae growth yet. Plants are still pearling, so I guess my light intensity was totally overkill back then. Hope this helps.

[samuelgoh]

hi, i had successfully eradicated BGA through the dosing 250gm of Amoxycillin (similar to Erythromycin) and various other measures to adjust my lighting period, circulation in the tank and CO2 input.

However brown hair algae remains at issue now, brush algae had drop off (most of them), but the ones on the DW are rather stubborn.

=)

Hi, I see. Didn't know you can add anti-biotics to your tank. I'm allergic to amoxycillin. Rashes broke out at my extremities including your-know-where when the doc gave me a strong dose of that IV. So, I'm still pretty horrified by that drug.

no worries dude, the cynobacter are allergic to it too =p

anyway how to deal with brown hair algae ?

[valice]

For BBA on driftwood, use an air tubing (with a siphon created) to scratch the BBA off the wood. The siphon will then remove the BBA out of the tank into a pail or whatever container you use to contain the water.

Similar for brown hair algae. After that use shrimps to remove them.

tried scraping off, but they really quite stubborn... not that easy to get them off...

tried that for the hair algae, it works.

still observing now , see how it goes for a few days before I update again.

anyway does cherry shrimps clear the hair algae ?

I find it very useful method using air tubing to scratch and siphon the BBA off.

If the BBA is on the tip of driftwood,you can try using ADA Python-Git.
After siphon off some water(let the BBA on the driftwood be exposed to air not in water), apply some drops on the BBA. Wait for awhile before topping up water.

I works quite well for me.

how much is this python-git anyway ?
