ID this neon-green algae please?

[chuaclarence]

Hi,

This neon green aglae appeared in my tank 3 days after I replanted it.

Any ideas what this is? Tried to find it online but I havent seen it before.

I scrubbed it off (it came off in sheets), 30% water change, and added some anti-algae solution. Any better way to prevent it from coming back?


Notes:

-The wood it is growing on; I had bleached it to remove the old bush algae, then soaked it in water to remove the bleach. The algae appeared mostly at the top, nearest the lighting.

- 6 X 36W Pl lighting for 2.5 X 2 X 2 foot tank.

Yap is BGA blue green algae. It is a form of bacteria that will kill all the fishes & shrimps.

any suggestion to rid the BGA ? have fiah too

It is due to dead spot in the tank. Have to manually remove it if not plant & fauana will die.

Quite common for an aquarium

1. 1st priority - remove it by suction (flakes of it will cause it to spread & multiply)
2. Introduce some algae eating fish or shrimps(will help in some extend)
3. Most effective "killer" of such are giant snails (but it a treatment & cure type - snails will feed on plants as well)
4. Ultimately light source should be the main culprit for its growth. Avoid contact with sunlight or reduce light intensity(usually not possible) - then reduce duration of exposure
5. I never/avoid usung anti-algae solutions (its not easy - too little= not effective, too much= plants die)

I had been fighting with BGA for sometime now and I seems to have found a way to control it. My BGA mostly occur on the top edge of my moss wall at the back of the tank.Had tried physically removal, applying H2O2, anti algae but without good results. Last week, while I was doing my regular water change, I applied generous amount of aquarium salt onto the exposed BGA patches. Then I proceed to clean up the canister filter. By the time I finish and refill the water, the BGA had been covered by the salt for around 1 to 1.5 hours. After I refill the water and had washed the salt away, I noticed the BGA had turned reddish. After a couple of days, the BGA had all disappeared. It has been one week already and the BGA had not returned. Will be observing to see how long before the BGA returns.

Probably tank has alot of mulm and together with dead spot or still-water it causes BGA. Clean your filter as well.

Blackout is highly effective.
BGA seldom goes away on it's own, just ask those that have had it in the past. A mild case might appear and go away, but this is a sign of something else.

Address the cause of the BGA to begin with and then it does not come back.

To that blackout method, add: 1/4 teaspoon of KNO3 per 25 gallons of tank, after the 50% water change, do another 50% water change at the end of 3 days.

From then on, add KNO3 to your tank regularly.
Plants need a fair amount of NO3 and K, when these are not supplied, algae will grow.

Antibiotics are no more effective than a blackout which is 100% Free and always available anywhere to anyone, anytime.

A very good general rule about algae snake oils and killers:
If it is not a plant nutrient, do not add it to your tank.

Take care of the plants and then you do not have algae. It really is that simple.
