Looks like a wildfire of algae devouring everything in it's path.
I think the green algae that is easily dispersed cover the plants thus causing damage.
Melting plant matter has brought on some but not much hair algae.
Quick dip of affected plant with an algaefix solution kills the hair algae.
The problem algae still remains though..
Hey MG, I don't think it was mentioned but does light reduction slow it down?
I reduced the right side from 115 to 85 PAR.
Think this stuff grows during moon light too.
Fascinating problem. I wonder if a level 1 UVS would tamp down enough algae spores to help in eradication.
Same UV I have used for green water doesn't touch this.
Buying another UV of some other type is not in the cards right now.
Damn dude that's awful! Yeah thats the stuff I was talking about, and wow you got it bad. Gonna be interesting how this turns out. I cant think of anything to help that you arent already doing.
Oh, it's the stuff alright, downright sinful, the spawn of Satan himself!
If I move species to my capped soil 33G this algae does not propagate.
It just dies off after a few days never to be seen again.
Both tanks are identical in parameters other than capped soil in the 33G.
Tomorrow I will have the media for the Diatom filter, lots of square feet of decking took up the day, so I didn't make the trip.
Going to trim in the 33G this eve and see if I can move salvageable plants to it.
33G is tight, almost completely filled, no visible substrate now.
Cleaning this tank and Poret foam is my concern right now.
I have peracetic acid, sulphuric acid, and HCl available but I am hoping bleach @ the right ppm will kill it.
Don't think citric and phosphoric acid will "kill" since they are very weak.
I'll pull algae samples from the next diatom filter change out and test in beakers with each.
By the way my phish are doing very well!
Rasboras & corys are loving life these days.
Till Another Eve:
