Folks,
Since I brought my new 120g tank on-line, I've been dealing with an odd problem not encountered in my previous 54g tank. I seem to have a fair amount of fine particles floating around in the tank...
The tank has been up and running for about a month now...
At first I thought my Tunze's might be kicking up some sand, so I shut them down to see what happens, but the problem persists. In addition, I get fine bubbles rising to the top of the tank, almost like my water is very slightly carbonated. The bubbles mostly rise off the sand bed, but it does occur from the rocks occasionally too. In addition, I see a fine "slick" of this particulate at the top of the water. If I stir it it will break up, but not dissipate. I don't think it's microbubbles, but really have no idea... I have tried large water changes to see if that helps, but it doesn't. With the powerheads on, it is somewhat noticeable. I have shut down just about everything (skimmer, carbon, etc) thinking something was pumping air into the tank, but doing any of those things doesn't alleviate the problem. Any ideas what's going on? Is this some sort of precipitate? I'm dosing Kalk...
All the fish and inverts are doing great, so that isn't a factor, but this issue is making me nuts!
Any ideas on what to look for would be greatly appreciated!
Thanks!
