    Hi all,
    So this is probably a very silly question but I was watching my fish today and to me it seems my fish are and always swim at a low level. I have two circulators on one side of the tank and one at the other end (pictures below).

    # 1. Are my fish annoyed because these fans too strong for them?

    #2. If I don’t have them on will there be enough oxygen for them?

    I have two large sponge filters and I also have a wet/dry sump in my basement right below the tank. I have no idea if this matters when it comes to oxygen! Lol I really have no clue.

    A lot of my tanks have just a filter and maybe a sponge filter, none have a powerhead or anything. Definitely not necessary. Lol those Severums hahaha.

    Alrighty, Thank you very much! I am going to leave them off. When I bought the tank and the whole set up for the tank they told me I had to have these fans because of the size of the tank. I wasn't sure if it was just for dead spots or for surface agitation.

    Is there a sump on it? Honestly as long as you have good filtration you’re getting oxygenation.
