crazy green film

[sharn]

on the top of my planted tank. its like the protein films you get but green its obviously some sort of algae related thing but i dont have a clue what it is :lol: the only thing i can put it down to was using plain flourish, i recently started using that and since then its popped up. i can lay a paper towel on the surface, remove half and have it back completly within an hour! spray bar faced at the top does nothing to break it up either

any ideas?

That's what mine was ages ago. Get more surface agitation and it should go away. Worked with me anyway.

Could be an attack of blue-green algae Sharn.

I get that often on my tanks if there is not much surface movement, some say its caused by the oil in human skin (if you have your hands in the tank), but I tend to think it come off the flakes/pellets fed and for some reason doesn't go up through the filter system. I find that if I put an airline it or move the filter so that there is surface movement it disappears.

another possibility is the in-balance of the ingrediant in your water.

could be excessive:

light - too near to the sun light 9or too near to the window with direct sunlight) for too long

fertliser - cut down

water change - not enough

it can also be too many or too little fishes and plants

Balance is the key.

i adjusted the spray bar to give it more agitation but the water moves under the film so it isnt really getting airated :lol: the only clear patch on the surface is right above the spray bar. ive done everything i would have to fix a protein film but it wont budge! it even has green bubbles on the top too

light is three 6500K bulbs (two three footers, one four footer) on a 144L tank (before substrate etc). those lights have been running a long time and this hasnt happened. the plants were all pearling before this came along. tank is across from a window but i have never experienced algae problems before. running a 1200lph canister.

ferts- im thinking this is it, i have stopped using flourish altogether now and havent renewed my nutrafin co2 kit.

water change- normally weekly, but sometimes i slack to bi-weekly. the plants seemed to be on top of things so i could do two weeks easily.

fish are stocked lightly. one angel, one aggassizi, three cories, two bristlenose, 8 rummies.

alan- that is not what i want to hear :lol: i like black beard and hair algae in low amounts (makes it look natural) but blue green is U G L Y!!

for now im gonna up the w/c's, might do a couple small ones a week and see if that makes any difference.

Get a surface skimmer and/or treat for BGA.
