Wait, could someone explain the ammonia spike issue? Would this be because of bacteria depletion?
from post # 487 ...
if the numbers were high enough, then ammonia levels could rise, just like what takes place in tanks when there is a bacterial bloom. But one should only experience this if they have a very large amount of organics in the tank, and they add a very large amount of bacteria all at once.
@thefredpit mentioned this happening in another discussion, when he added an undetermined amount of Rid-X to his tank when there was a significant build up of organics, that had accumulated when I believe he had not been using Rid-X for a while.
The idea is to do this process gradually, not shock the aquarium with a shovel full of probiotic bacteria, added to a tank that is already choked off with sludge. I'm exaggerating of course, but a little goes a long ways, and one shouldn't expect bacteria to replace general maintenance of ones tank, including filter media and regular siphoning of substrate etc.
Used on a regular basis, in a limited controlled amount, these heterotrophic bacteria will convert excess organics to carbon dioxide, ash, mineral, gas, and water, which are then removed further via aeration, plants, and regular water changes.
Another real risk to overdosing with massive amounts, especially in a sludge filled tank, is 02 depletion.
People need to be sensible when using these products. If not, then operator error could prove to be fatal in extreme situations.
