Its a 3weeks old 30L tank with hamiantus calitrichoides foreground and stem plants on the back and about 15 small fish among them only 6-7 oto's no other cleaners.
since day 4-5 i have this nightmare. it wont leave me even after 40-50% w/c every other day and 3 days dark period.
cant use UV light there as it is too small.
is there any other solution, maybe chemicals ?

no3 - 10
ph - 6.4
co2 every 1 sec
amano aquasoil and 18w sylvania gro-lux+18w philips aquarelle

nop!
ill give it a try - why aeration during lights out could help?

by the way it a "water fall" kind filter - dont know its name but it hangs on the side glass , sucking water from the tank to its body and they are falling back to the tank.

thanks tom
from all the above i can only try copper or h2os - dont have diatom (realy expensive here in israel), my UV is too big and ive tried to darken the tank. could u give me dosage and tips how to kill it with h2o2 in a small tank"?
in case nothing is working - how do i start all over with out getting it again? how do i clean the substrate (aquasoil) ? should i recycle it again?

ok problem solved - yesterday i could see the fish and now i can c my downey growing slowly... just had to b patience and 50% W/C every other day + a few drops of ferts + K from kcl on a daily basis. full of fast growing plants+floating plants (riccia+duckweed and more) . the plants looks a bit weak but they will survive.
not sure if it had any efffect but i dosed a few drops of h2o2 in the last few days with every w/c

hi tom, what do u mean?
if i dont c it at the moment and the water look clear - why should i care ?
im sure i have a few other kinds of algae . if they dont bother the plants (look and growth) and if i dont c them - i dont care they are still in the tank.

u r right, but a day or two after the water was crystal clear.
well not crystal due to the aquasoil, but clear
