It hasn't affected much yet in almost 2 weeks but I have some concerns about my water. The surface of the water isn't clear...its like a dust or film has settled on top. The rest of the water is fine but I can't do anything about the surface.
My biggest concern with it is that it is definately impacting the amount of light my plants are getting. For a week I pointed my Cascade 700's output at the surface to try and stir it up but it had little effect (it did help some but not entirely) Now that I'm adding CO2
I don't want to do that anymore.
I've done water changes but since its on the surface of the water that doesn't do anything to get rid of it since its almost impossible to skim the surface. Its probably dust from the substrate I added a couple weeks ago.
