I used to have the same problem that you have and , I did a lot of water changes, built a 100 gallon box to create extra water volume, and create a real tsunami inside my tank:lol: I have four pumps, in each side!!
I dont know about the white things but you should try to get away, even though I love the cucumbers and sea apples (I have 2 pink/green cucumbers and two sea apples) they need to be feeded everyday and need to stay away from waterpumps and that stuff.
If you could post some pics from the white...
thanks for the suggestion but I couldnt get him out from his bag (He died in there like in 3 minutes!!!) I was waiting for the temperature in the tank to get at the same temp, that the bag :(
Today my watanable angelfish finally arrive, in fact he is in the aclimatation progress but he is infected with ick, I just reallize it when he was under the light in his bag, I dont have any qt tank, what can I do:confused:
I have 4 hippos, a yellow tang, 3 green chromis, and two clownfish!!
I was worried about the bioload so I built a 100 galon box only for add more water volume to my system:D . I dont know if that was a good idea:doubt:
Then you have to pick the stuff out w/o popping the bubbles. Don't let any of the stuff stay in the tank, or you'll never get rid of them...this is how I've gotten rid ofmine.
