for some time now i get like a crust on the top of my water. like it drying up. what is that? what should i do?

 

[chrisaggie]

do you use kalk?

 

[esc.nuk3r]

nope

Could also simply be an organic build up if the surface water isn't being effectively skimmed.

 

[chrisaggie]

Can you get a picture? Do you run a sump? Do you have a skimmer?

Is the film in the sump or in the display tank?

 

[esc.nuk3r]

display tank

 

[coralfragger101]

Sounds to me like an organic film. How is your overflow set up?
You need to get some surface action going pushing that film through your overflow.

This film will decrease the gas exchange between the air and your water so this problem really should be resolved.

could it be from not having good flow in the tank

Very possibly. You should easily be able to fix this problem by creating different water movement which will cause the surface water to be skimmed by the overflow.

 

[coralfragger101]

Yes. You need to get some flow going that pushes that surface water towards your overflow box.

i just did that . that should do it right . problem is that i have i penguin power head and another sweeper and i have a return from a mag5 from the sump but when i start moving them around i dnt get the flow i need around the tank. any advice?

Use the deflector on the penguin and point it up towards the surface.

 

[esc.nuk3r]

i lost it

 

[coralfragger101]

LOL. If it's the same deflector as on the maxi's I'm sure I have a spare laying around. If you are a die hard DIY'er then you could cut a small notch out of the top portion of the outlet tube and then heat it up a bit and bend what's left up a bit. That would probably work as well.

i think its working the way i put it
