    Hi guys. I need help with these. I noticed loads of these tiny sponges growing all over the glass in my sump and a few in the DT. Is it good or bad? If bad how do i get rid of them?

    as far as i understand they are harmless, actually good as they filter water, more than that i unfortunately do not know.

    I do know that bit but they seem to be spreading quite rapidly.

    Have you increased your feeding recently? Done a big harvest on any macros? Anything that's letting them grow?

    I have one in my DT under a piece of LR thats +- 2cm and it grew to that size within a month. I'll try and get a pic later. its in an awkward corner though.

    They did come on a piece of LR. I didnt know what it was at the time. Hope they don't take over the tank though.

    Do you have a light in your sump?

    Yes I do. its a 150W halogen floodlight. Its on for like 3 hours a day. These sponges do not grow in light. Maybe I should leave it on for longer if these sponges get out of control. I'll need to install some PC fans in that case because of the heat from the halogen lamp.

    I would leave them in the sump, they are feeding and that means they are cleaning.

    Yeah, i was going to say - i don't think you have to worry about them growing in your DT, as they avoid the light. Lots of guys incorporate a "Cryptic zone" into their tanks to encourage these sort of things. They're great for your tank :)
