I think I have BGA

[250Gimp]

HI All

I need some help confirming that I have Blue Green Algae.

I am no expert, but from the reading I have done I think that is what I have.

Here is a pic of my tank:




Let me know what you think, and I would apreciate any tips for removal.

The tank has 2 live plants, driftwood, and is lit for about 9 hours a day (used to be 10, but I cut back). No Phosphates, 0 ammo, 0 nitrite, 5-10 nitrate.


Thanks

I should mention I have some have shrimp I. The tank.

what type of light are you using? if the spectrum is too blue (ie higher numbers) then that could cause it. if BGA was not an issue before and is now then maybe its time to replace the bulb. you can try to black out the tank for a few days that could kill it off.

Thanks genocidex

The tank is fairly new, started in late October.

I don't know the light spectrum as it is led's from Eheim that came with the kit.

I got a bit of BGA when the tank was very new, but I thought I had it under control. It now is expanding.

ok what kit did you get that might help us. leds can be in loads of spectrums and its possible you got a 10000k led and thats causing bad algae....

If memory serves me correctly, that appears to be a form of nostocular cyanophyta, which tend to produce the highest amounts cyanotoxins. My advice would be to remove the affected matter from the tank immediately, and to vinegar the wood, and bleach the rock. I don't have experience with any chemicals added to the water for cyanophyta removal, but I will say that be that it's always better to under dose then over overdose. Hope this helps!
