got white film kind of stuff floating on water donno wat it is ,,,any idea???

could just be a film from breaK down of food waste.

what sort of surface agitation do you have?

i dont over feed the fish ,,just feed them blood worms n make sure no wastage happens.. also i did water change but it still there ..

its kind of white colour n wen stirred it turns fine dust nd sink

Blood worms aren't good as a staple food - they're not that nutritious. They are more of a treat :spop:

How much ripple do you have on the surface? Try increasing it, but keep an eye on your nitrate/nitrate/ammonia. If it's an organic film, it could raise N/N/A as it decomposes in the water column.

Is it a new set up? You can get a bit a film initially until you do a couple of water changes and your tank's bio system reaches an equilibrium and settles down.

its not that thick ..and i m doin regular weekly water change so as to reduce ammonia and nitrate

it is kind of new setup coz i changed whole lot things and started as new ...but this film just appeared recently

don't panic about it, it's normal as far as i can tell. My "less aerated" tanks have it but i have never had an issue.

You never answered the first question in your thread. If you want results, read what's given to you.

surface agitation? could u please explain it for me wat he really mean ..sorry my bad english

Surface movement of your tank

oh thanks guys .. i thnk it s very less in my tank coz its a fighter tank they don like it much >>

you could try putting your filter return just above / close to the water level, or use an airpump

I find you normally get a bit of a film build up if you dont break the surface tension

k ll try to do somethng for the surface tension..

skim a paper towel across the surface

got a airpump installed now got it on controll:) thanks a lot people
