Despite doing just about everything that i've read to address this, i'm persistently getting staghorn algae and some GBA.
The staghorn is mainly affecting Juncus Repens, and to a lesser extent the Weeping Moss. It is not touching the Rotala or Hydocolyte or Crypts. Trying to pick it off with tweezers is a pain in the blahblahblahblah!
The GBA is only affecting the Juncus Repens.
Tank specifications - 15l
Lighting - Azoo Flexi-mini LED, on from 5pm to 10pm, tank sits on an east facing window ledge so gets some light all day, but not direct sun.
CO2 - Pressurised, from 7am to 8pm
Filtration - internal, claimed 100lph, cleaned weekly, spray bar
Fertilisation routine - EI
Water change - 2 x 75% a week
Fauna - 6 cherry shrimp, 3 amano, numerous juvenile Ramshorn snails (i think, they just appeared).
This http://www.theaquaticplantsociety.org/flexi-mini-nano-led-follow-up/ reckons the Flexi mini puts out 203 PAR at 2inches (presumably below water surface). In practice the light sits one inch above the surface of the water and the Juncus Repens and Rotala touch the surface, so i presume the PAR is even higher than 203. I've read George Farmer on here calling 250 PAR "insane" for a planted tank.
So for all that it's a pretty simple question:
Do i have too much light?
I cannot dim the unit. So options would be to raise it (which will require some DIY) or cover some of the LEDs, my guess would be that raising it would be preferable to get an even spread of light?
Sorry this is no doubt an old chesnut.
