what is this and how can i get rid of it?

this keeps happening. i have a spray bar, but it's face downward some. i'm pretty sure this is from no current on top of the water, but if i turn the spraybar upward some, then my co2 floats to the surface. i don't want to use a powerhead because i'm trying to keep a clean look to the tank. any advice, suggestions?

Yep, surface scum, get a skimmer.

When was the last time that you vacuumed the substrate, I get that when I dont do at least a light vacuum every few months

i think it's the co2. i did a vacuum last night, so that can't be it. i've always fed this foor and never had a problem. it's been ever since i added the spraybar. i'm pretty sure it's from lack of surface movement and a lot of co2.

I used to get that when I had DIY co2. But not since I went to pressurized co2.

Do you have Gouramis or Bettas? They make bubble nests. When I had Gouramis I would see foam like that on the surface surrounding my plant cover.

But..it is really hard to tell what it is from the photos.

It's a layer of protiens and bacteria, surface scum, and yes the lack of surface movent has something to do with it. Before your spraybar you had greater surface movement and that kept this material suspended and didn't allow it to collect at the surface. What you need to do is introduce some surface movement, either adjust your spraybar or add a skimmer. This will cause some loss of CO2 but it may not be that significant.

i adjusted the spraybar a tiny bit just enough to give a little movement, and today, there is nothing. all gone. thanks for the replies everyone!

I've made this same statement many times over... Lift the spraybar or lily pipe to break the surface during offlight hours the reasons are twofold:

1) Aeration of the water is an advantage to plants and fish.

2) Clean surface.

Lots of tanks go through this phase at some point or another, easy fix.

Yes it will go away by itself as long as you have a ripple on the suface. Pretty much a new tank type syndrome.Like Craig said...Easy fix.

Ya really dont need a surface skimmer...

Just get some movement on the surface...
