Help please!
I Agree except the for the fact that Your Benificial Bacteria Need a Large Supply of Fresh water and OXYGEN flowing past them in order to grow or survive as they are oxidizing bacteria.. depending on your filter if like mine when turned off mostly drains back into the aquarium thus drying out my filter media the filter and potetionally killing your bacteria if prolonged.. or if it does not dry out their no longer being supplied with oxygen they need?.. couldn't find studies that said how long bacteria can live with out fresh oxygen supply Caliban07 if you had that article i would be interested in reading it.. but if you were to have a power failure like you did for six to 7 hours in a newly establishing aquarium i would think it could be enough to through off the nitrogen cycle..?
from what i found online
"All species of nitrifying bacteria have limited tolerance ranges and are individually sensitive to pH, dissolved oxygen levels, salt, temperature, and inhibitory chemicals. Unlike species of heterotrophic bacteria, they cannot survive any drying process without killing the organism. In water, they can survive short periods of adverse conditions by utilizing stored materials within the cell. When these materials are depleted, the bacteria die." and nitrosomonas tend to be more sensitive thus with no flow through filter i would think they would use their stored materials and possibly die i guess depending on the length of time required to deplete their stores which i couldn't find?

Guys, i noticed my water is cloudy since yesterday and i can see something in the inside of the tank. Seems to be white-ish... What is this???
Is it algae growing? Fungus?
My goldfish are sick... Wonder if this has anything to do with it, or its an issue with water temp...
Bacterial blooms usually occur when a tank is at the beginning of its cycle (like a new tank) or if the balance in the tank as far as the bacteria are concerned has been disturbed.
Throwing filter sponges or other medias away and replacing with new or washing filter media or ornaments in tap water will cause this.
Also changing the substrate or doing a very big water change (>50%)
Can you please explain how doing a 50% or greater water change is going to affect an established tank's cycle?
If this were the case, the majority of the members of this forum would have constant tank issues, including myself. Considering I do 75-100% often, if not daily on fry tanks, perhaps your theory is lacking substantiation.
