As for my sis tank....
After many hours of staring into the tank I found the green water problem and its now fixed.
The whisper filter that she has (like all whisper filters) has a spot for 2 suckioncups (yes I can't spell). Well she only had one on it. So I asked her where the other one was and she told me that it only came with 1. I am guessing that someone stole it out of the box at walmart. What I had thought was the hole where the cup should be was pushing water out of it, and thats where the problem lies. The water that was comin gout of the back of the filter was not getting cleaned and it was just putting the gunk back into the tank. I made a temp-fix with a peice of plastic and now the tank is little milky but lots better.
Today at the LPS I got some fix a tank stuff for cracks and all that. I used it to seal the hole on the back of the whisper filter. So in 24 hours I will put it back in that tank and we should be good.
