I doubt it's from my hands, I wash them about 100 times a day. Could it be from left over food? Had problems with a few fish not eating and I couldn't get all of it out
Should I do like a 20 percent water change? Will fhat help
I highly highly doubt it was from your natural oils in your skin. I put my hands in my tanks multiple times a day and have never had this happen, it is something else. Just do a water change and feed a little less and see if that works. You could also get a bubbler, and only turn it on when the lights are off(since you have plants).
i generally only use soap in the shower, i just wash my hands a lot out of habit without soap. I also don't use lotion very often. But, i will keep my hands out of the tank as much as i can
Reading through the thread I think it may be your food. What do you feed? I sometimes notice this after I feed flakes. And I rotate flakes/pellets/bottom feeder tablets ect. Read the ingredence list, most foods have some sort of oil.
