n00b Question: Green Slime? (how to kill)

dude, that looks nasty. IDK on any info about it, but maybe salt would work. And frequent water changes.

I know I agree with you, it just started one day and looks terrible! This tank has zero ammonia, nitrite or nitrate readings what so ever. It's a aquaponics tank (plant filtration, no filter). I do WC's for mineral replenishment only (every other week about 20%). Do you think that might be contributing to the problem?

More info: pH 7.6, 65-72 degrees (cold water tank, no heater), Marineland LED's on for 8 hour per day period. The Tank gets direct sunlight but no green water or algae issues. Circulation is Eheim 2211 canister with no media, only sponges. I have not tested gH/kH or TDS. Tanks been running 6+ months.
 
uhh.. i used to have this too.. i believe its called blue/green algae. its a wierd thing, since its algae, but not, becuase it has bacterial tendencies as well. i think aeration helps clear that up, cuz since i got a filter that stuffs cleared up rather quickly.

yeah, I think a filter temporarily would help quite a lot and an aerator as that is what masshiimarro says. I would add a permanent filter on your tank except I would have it run only once a week after all the algae is gone.
 
Nice Axolotl. I've heard excel has anti-algae tendencies. That might be worth a shot as well.
 
BGA, more technically known as cyanobacteria...one of the suggested causes is low, low nitrate which makes sense in your case since the tank is void of any. Might be good to target dose, I bet the plants would appreciate it!
 
Hydrogen Peroxide is great at getting rid of BGA too. Turn off the filter and wait for the water to settle. Spot treat areas of BGA with the peroxide and wait for about 20-30 mins before turning on the filter again.

Well, it's not that weird. It's bacteria, it isn't algae, it's really as simple as that. It doesn't have "bacterial tendancies"; it is a bacterium.
 
Its BGA, More bacterial that algae. Its a photosynthetic bacteria, or something like that.

I had it covering 1/2 of my 125.
Its pretty easy to remove just by peeling it off, but it comes back.
many people swear by a 3 day Black out, but that didnt work at all for me. I treated my tank with 1/2 dose of maracyn for 3 days ,and it was gone.
