    Pretty much self explanatory, i noticed it right now when i was getting ready for a water change. Its at the top part where the water doesn't touch it. should i be worried or is this just good bacteria?

    If you use StressCoat it could be aloe vera residue.

    I only use Prime and i only put it on the new water containers, not directly to it. Can this be harmful or i shouldnt worry?

    Unless it is a soap or detergent residue, I wouldn't worry too much about it. I've read other threads in the past about white foam, and I can't remember what the responses were, but I seem to remember it not being a problem.

    Ok then i can relax, i'll keep a close eye on the fish to see if any stress is shown.

    Thanks jdhef

    Oh i have another question, is there such thing as too much Prime? i use Prime in every water change.

    If you are using the correct dosage with every water change, it is fine.
