I just installed my ASM g-1 skimmer up in my sump. but i dont know if its working right. I get large bubbles that just go straight up. It was my thought that they should be very fine bubbles that spiral up. I also thought it should be so full of smal bubbles that you would not be able to see threw it but its ever clear with large bubbles. The tank is only filled with RO water right now. NO livestock at all or salt.
